Cobb & Co. Part 1: Fenella Hut

 Overview: I start a trip to Kahurangi National Park's Cobb Valley area with an overnight tramp up the Cobb River to Fenella Hut.

After an early morning flight from Wellington and a 2.5 hour drive from Nelson it was with some relief that I eventually reached the parking area by Trilobite Hut at the end of the dramatic Cobb Dam Road. A thick, soupy cloud surrounded the valley and a light but persistent rain was falling. I had half a mind to set up shop at Trilobite and spend the afternoon with my feet up in front a warm fire, but nevertheless I got ready for the tramp in to Fenella. It was now that the first a few faux pas was revealed: I'd taken the insoles out of my boots to dry them out after cleaning them in preparation for this tramp. I had not put them back. Sighing as I pictured where they were sitting in my house, I plucked the insoles out of the sneakers I'd been wearing and stuffed them into my boots in the hopes they'd suffice.

The track begins in beech forest, and moves in and out of forest and open flats up the Cobb Valley. There is minimal change in altitude, the track is about as flat as a tramping track in the mountains can be. The track itself is also generally well maintained and makes for an easy walk.

 

 

The drizzle was constant, but never heavy. After a quick 6 km, I reach the historic Chaffey Hut. Originally built by Forest Service rangers in the early '50s, and authentically restored in 2012. It was a welcome shelter from the rain to take a short break, as well as being a really cool, rustic piece of history. Alas this was not my destination and there was still many more kilometres to go.

As the track heads further up the valley, the grassy open areas transition to tussock. In places the the tussock encroaches significantly onto the track. It was thoroughly sodden, so walking through it soon had my legs saturated. It is times like this that lend credence to the superiority of shorts over hiking trousers - wet skin is far less uncomfortable than wet pants sticking to your legs. Shortly after Chaffey, a footbridges crosses the Chaffey stream and the track begins a very mild ascent through some stunted beech forest for a short time before entering a prolonged section of open tussock. Eventually, another historic site is reached - a restored tent camp from Forest Service deer culling days.

 

Chaffey Stream

A rotund weka was milling idly about the tent camp, outwardly indifferent to my presence but no doubt waiting for the opportune moment to engage in a spot of backcountry larceny, as is their wont. The tent camp looks surprisingly cosy inside but onwards I must go.

Thankfully the rain had temporarily abated, making the continued walk through to the head of the valley more pleasant. The track passes through more beech forest, often rocky, the stunted trees at times draped in robes of lichen. Shortly, Cobb Hut is reached.

 

The basic Cobb Hut has a certain rustic charm, nestled among the trees on the edge of open tussock, and it provides a great shelter before the final thrust up to Fenella. After leaving the hut, a signposted junction indicated tracks to Lake Cobb and Fenella Hut. The track to Fenella now climbs through the only noticeable elevation change, but even then it's only modest. It's a damp and rocky ascent. Close to the hut, the track is whimsically paved with an assembly of foraged schist. After passing through a final tussocky area the hut is finally reached tucked into a clearing in a hilly patch of forest. 

I arrived to find two other trampers already in residence, with the fire already going and the hut toasty warm.
The hut is kitted out with an oddly residential looking gas hob and a weirdly shaped back room that I imagine may have once been rangers quarters. Up to 14 people can be accommodated on the platform bunks. The dunny is perched on a steep hillside below the hut (a steep, slippery walk in the wet conditions) and features a stained glass window in the door. The second of my series of faux pas became apparent here: I'd completely forgot to bring toilet paper. Luckily a previous visitor had left half a roll that I gleefully annexed. the alternatives do not bear thinking about.

The next morning, yet another weka stalked around the decking while a sipped coffee. Robins and tomtits flit between nearby trees. There's a light rain falling, but brief openings in the cloud offer tantalising glimpses of blue clear skies. The forecast is for the weather to clear. I'm hopeful. 
The pair of trampers leave early, heading out close to 8 am into what was probably the heaviest rain that morning, whilst I'm barely contemplating breakfast.
About 2 hours later the rain has stopped and I'm making my way back down to Cobb Hut. Once there, I elect to take advantage of the now much improved weather so I dropped my pack and made to short side trip up to Lake Cobb. It's bit of a slog, but short and well worth the effort.







Lake Cobb sits in a steep-sided mountainous bowl, typical of areas shaped by ancient glacial erosion. The distinct rocky edifice of Xenicus peak dominates. From here, a track crosses the outlet stream and continues on to Round Lake. I later heard from a volunteer checking traps that this track meets traplines that can be followed in a loop to Fenella Hut - apparently a worthwhile exploration I wouldn't mind doing myself one day. This time though I did not continue, instead heading back to Cobb Hut to reunite with my pack and walk back out to Trilobite Hut.

I passed a big group heading in on my way out and ruefully considered how much better their timing was vis-a-vis weather. By the time I'd reached the tent camp, the sun had well and truly burnt off the worst of the cloud and conditions were dry and pleasant. The improved weather seemed to have bought out plenty of birdlife - I heard and saw plenty of robins/toutouwai, tomtits/miromiro, riflemen/titipounamu, bellbirds/korimako and of course the ubiquitous weka.

 

 
The picnic table outside Chaffey Hut made for a brilliant spot for a late lunch in the sun. A few weka materialised from nowhere the moment I sat down, one particularly gormless one made the interesting choice to climb, and then jump out of, a nearby shrub - something I found far funnier than it was.

The rest of the tramp passed in a pleasant sunlit placidity. 6 km from Chaffey I was back at my rented Hyundai, and preparing to settle for a night at Trilobite Hut with its ideal location at the roadend. I had a robin perch on a log and watch me chop firewood and weka keeping me company while I drank a well-deserved beer in the setting sun. A great end to a great day and a great tramp.
I later found out that it was almost 30 years to the day that Kahurangi National Park was officially established (5th April 1996), a serendipitous coincidence. So in hindsight it was also a great way to celebrate the 30th birthday of New Zealand's 2nd-largest national park too.

 

Unfortunately, dinner time at Trilobite revealed my final faux pas: I'd left my favourite spork at Fenella Hut.

Routeburn Track

Overview: three days crossing the mountains between Mt Aspiring and Fiordland National Parks on one of the classic great walks.

Hopping off the shuttle at the Glenorchy end the Routeburn Track, it's hard not to be impressed by the towering peaks surrounding the valley. The track begins with a footbridge over the Route Burn, before rambling upstream on the river's true left through lush beech forest. After 2.5 km, a footbridge over a small waterfall is reached. From here the valley narrows considerably and the track begins a sidle along the steep hillside above the river. 

 

 

  

The track climbs steadily but gently up the valley, becoming fairly high above the narrow river gorge. The gorge section extends from ~2.8 km up the track to the ~4 km mark. Through the trees, impressive rock formations and the startlingly glacial blue water of the river can be seen.
About 4.1 km in, a short diversion off the main track leads to a riverside area called Forge Flat - a great place to stop for a quick rest.


  



Route Burn at Forge Flat

From Forge Flat, the valley opens up and the track continues winding through the forest for another kilometre before crossing to the true right of Route Burn via a disorientingly swingy suspension bridge. The track is nice and flat so it's an easy walk to reach the turn off to Routeburn Flats hut, located on the edge of grassy flats at the confluence of the directionally inconsistent Left and North branches of the Route Burn. It's a quick 5 minutes from the main track to reach the hut.
Routeburn Flats is the smallest of the three huts on the track and is often skipped by trampers who more often stay at nearby Routeburn Falls Hut. 

Curiously dry stream bed.


Routeburn Flats Hut


Sadly, Routeburn Falls sits on the edge of the mountainside overlooking the valley, so back at the main track the climb begins immediately and never really lets up. It's not especially steep, roughly 250 m of altitude is gained over 2.5 km, but it is constant. 



The first building to appear is the private Routeburn Falls Lodge, which looks down of the Routeburn Falls DOC Hut, its lights shining ostentatiously and generator humming in the background. Though being a Great Walk hut, Routeburn Falls Hut is hardly slumming it. The hut sits right on the edge the mountain with fantastic views over the Route Burn valley. It consists of two connected buildings, one housing the common areas and the other two large bunkrooms. The bunks are all individual rather than the usual platforms found in most backcountry huts, which is a nice feature. Between that and the earplugs, I managed a pretty decent sleep.



A light rain had built up over the day and was well and truly settled in the next morning, along with a heavy mist. On day two, the track now heads further into the mountains, an area known as the Harris Basin - a tussock covered bowl surrounded by high peaks looming the mist. It's at once enchanting and slightly eery. The cloud seems to muffle all sound beyond the patter of rain on my jacket hood. Though I know I'm on a great walk track and there's at least one group of trampers 5 minutes behind me, I could be completely alone in the deepest reaches of the southern alps.








The track climbs through the Harris basin and a wide variety of alpine flora and rock formations. The altitude tops out close to 1300 m as it sidles around Lake Harris, almost 3 km from the hut. Chances are if you've seen only one Routeburn promo image in your life, it's probably one of the track cut into the steep hillside above a lake - Lake Harris. No chance of getting such a photo today though, as the lake was almost entirely hidden in the soupy fog. The briefest of glimpses were available when small pockets of cloud were blown around.




A hint of Harris

This is not Lake Harris, this is only a tribute

After Lake Harris, the track passes a tarn and the Harris Saddle is reached. There's a shelter here, though I took my break standing on the decking under the eaves that I deemed to be more inviting than the loud, damp and honestly pretty ripe crowd inside. From here there is the option to take a side trip to the summit of Conical Hill, apparently 1.5-2 hours return. Given the likelihood of finding only more cloud up there, I decided I couldn't be bothered and instead continued straight on to Lake MacKenzie Hut after a couple of exceptionally dry cheese and marmite sandwiches. Quite why Vogel's bread is so revered I will never understand.
From Harris Saddle, the track turns south and begins to descend across the Hollyford Face. Far below is the Hollyford Valley, across which lies the dark silhouette of the Darran Mountains among the mist.





Spot the Kea...

The track here undulates a bit but is generally shedding altitude. The surface is often rocky and gives the ankles a good workout. There are some impressive views down into the Hollyford, and Kea whirl overhead. 8.3 km into todays walk, the track turns sharply around the spur below Pt 1310 to begin the descent to Lake MacKenzie. There's a nice little plateau at this prominent corner (which I think might have a name that I can't remember) that would make a good place for a rest, though given the weather I was more interested in continuing on.
Cresting the corner opens up views down to the lake and, tauntingly, the hut beside it. It's a quintessential case of so close but so far as there's still ~2.5 km of walking remaining, despite how close the hut appears.
The track zigs and zags down the steep mountainside, eventually descending into gnarled, mossy beech forest, amongst which is strewn huge jagged boulders.

Lake MacKenzie does not extend quite as close to the track skirting its end as maps might suggest, the shoreline rather sits close to what appears on the map as an island. There's a field of boulders and scrub, and a sign the points to a flood diversion track. Presumably the lake can inundate this area in the right (or wrong?) conditions. 
I'd had a goal in mind of reaching the hut by 3 pm. There was no real reason for this beyond the vague forecast of rain increasing through the afternoon. I pretty much met this goal, and a good thing too because I'd not long claimed a bunk, changed into dry clothes, and put some water on to boil that the rain really began to settle in.
Lake MacKenzie Hut consists of a series of buildings - the main hut, toilet block, additional bunk house, DOC ranger cabin, and at least one other small building of indeterminate purpose. The main hut building consists of common areas on the ground floor, and an upstairs bunk room. Curiously, accessing the upstairs is via a separate external door that requires a brief exposure to the elements to reach.
I'd heard talk over dinner of a so-called "split rock" nearby, so the next morning I moseyed off along the track around the lake, following the sign for split rock track and the MacKenzie camp site. 
The campsite and shelter are an easy 10 minute walk from the hut. From there, the track becomes a more traditional backcountry track but it's still an easy 10-15 minutes to reach split rock, which is located pretty much where the track marked on topo maps ends. The name is self-explanatory but understates the scale and bizarreness of the reality. 
After the short walk back to the hut, it was time to saddle up for the final day on the track.
The track initially passes through low shrubs adjacent to the private MacKenzie Lodge before entering the bush and beginning to ascend toward the bushline. The section of track between lakes MacKenzie and Howden is frequently rocky and has suffered substantial storm which has largely been repaired though there is one particularly steep and slippery diversion around a significant washout.
The heavy overnight had brought out many small waterfalls that would otherwise be less impressive trickles or even non-existent.





The track levels out somewhat after reaching the bushline, and spends the next 3.5 km meandering around the 1000 m contour before descending again after Earland Falls. Shortly after reaching the bushline, an area know as The Orchard is reached - a clearing dotted with mountain ribbonwood trees which have a marked resemblance to pome fruit trees. The ribbonwoods first started making a prominent appearance on the descent to Lake MacKenzie, where they struck me as looking particularly exotic (i.e., not native). The large stand outside Lake MacKenzie hut prompted me to whip out the Aotearoa Species Classifier app which informed me that they were in fact the native mountain ribbonwood.
After around 3 km of scooting along the bushline, the spectacular Earland Falls is reached. I was peripherally aware of the falls as a point of interest on the track, but I lacked any real awareness of exactly how phenomenal they are.
Plummeting over an edge some 174 m above the track, the torrent of water rushes and crashes down, the force of it creating a tangible gale and a localised rainstorm. All no doubt amplified dramatically by the overnight rain. Emerging out of the forest onto the base of the falls was like entering a maelstrom, and I was thoroughly sodden by the time I back in the shelter of the trees. There is also a flood diversion track that diverts down from the falls but where's the fun in that.
Distant falls

Now I'm always a fan of even halfway decent waterfalls so suffice it to say that Earland Falls blew me away (almost literally) and were undoubtedly one of the highlights of the trip.
The track now winds down toward Lake Howden, once the location of Howden Hut before it was terminally damaged by a landslide in 2020. 
The landslide is still visible, and in fact forms the basis of the track away from Lake Howden. In what I also suspect to be a consequence of the landslide are some semi-submerged trees at the outlet of the lake. At the Howden shelter, which was once again full of clueless guided goons (including a woman who whipped out and inflated a mini sleeping mat type thing seemingly to avoid having to sit on the bare wood of the bench seat), I had the pleasure of a visit from some weka while I snacked.
 
Robin in a spooky tree

From Lake Howden, there is yet another hill to climb up yet more rocky track to eventually reach The Divide. Less than a kilometre from Howden, there is a side track to Key Summit. It's apparently 1 hour return but with the heavy low cloud once again promising to hide any potential views, and lacking the mojo required to choose more optional uphill walking, I continue on the Routeburn Track proper.
From here it is a constant descent through more picturesque beech forest, glistening in the drizzle with something the DOC ranger at MacKenzie called "liquid sunshine."
A loud motorbike tearing up the Milford road drives home the reality that the track is almost over, and soon enough I'd arrived at The Divide to await the Tracknet shuttle to Te Anau, where a hot shower, real bed, and (most importantly) a pub were calling.
Without doubt a walk worthy of the "Great" moniker, a great experience all around, and one of the best tramps I've ever done.
