The Tongariro Northern Circuit

One of New Zealand’s Great Walks, the Tongariro Northern Circuit leads you into the jaws of the North Island’s most active volcanic landscape. The path passes through stunning mountain scenery dominated by 3 active volcanoes, Tongariro, Raupehu (the highest mountain in the North Island) and Ngauruhoe - the legendary Mount Doom in the Lord of the Rings – welcome to Orc country! 

We set off from Whakapapa village, a ski centre during the winter, but in summer bustling with trampers, day trippers and backpackers. We carried everything with us for our 4 days in the hills, so the packs started out a little heavy with enough food for the trip.

Perfect weather for the start of our trek, the cone of Ngauruhoe our destination

The track climbed gently above the village, undulating through moss ridden forests, weaving in and out of narrow gorges and streams. The narrow path was heavily eroded through the soft ash-laden soil.  We passed charred trees preserved in this soil, remnants of the forests once here, destroyed during the super volcano eruption of Taupo in 26,500 years ago. This enormous eruption reshaped this part of the North Island and lead to the creation of the 616 square kilometre Lake Taupo to the north, New Zealand’s largest lake, which is effectively a huge caldera.

The weather was clear, blue skies and a hot sun that burnt anything that wasn’t covered up or creamed. Despite the popularity of the trail we met only one other walker on that first day until we reached our quarters for the night at the Mangatepopo hut. It was a cosy affair with three small dorms, a tiny kitchen with three gas burners, a few small tables and a large veranda to bathe in the evening sunshine.

23 people squeezed into the hut that night with another 10 camping outside. We opted for an early night and early start the next morning as the next section of the walk is known as the Tongariro crossing, the most popular single day walk in New Zealand with over 1000 people a day attempting it during peak season i.e. right now.

The hut can just be seen nestled under the ridge leading to the summit of Tongariro

We were up at 5.30am and away just after 6am. The track here is well maintained and weaves through and over lava fields under the shadow of Mount Doom. We were one of the first few on the track as we left the scant vegetation behind and the ascent steepened up to the saddle between Ngauruhoe and Tongariro. After the saddle we crossed the south crater floor, an endless white basin half hidden in the clouds. The weather was poor, visibility of around 100 metres and winds gusting over 40mph. But the forecast was good, so we continued upwards and left the main track, twisting and turning along a basalt and scoria ridge to the summit of Tongariro lost in the clag.

We retraced our steps to the main path and now joined the catching crowds passing the red crater, when all of a sudden the clouds began to break and strange vistas began to unravel before our eyes. Ngauruhoe loomed over us, the red crater spewed its steam, the yellow crater stared back at us, its sulphur crystals glinting in the sun and the emerald lakes shimmered like cats eyes on the plateau below us.

We descended the cinder scree run to the dazzling lakes, steam drifting from smaller vents around its shores which were fringed with vibrant oranges and reds.

Here we left the crowds to complete their crossing and headed east toward the Oturere Hut. Pumice crunched and squeaked under foot like freshly fallen snow as we flowed down the lava fields and over the remnants of pyroclastic flows.

The hut was even smaller than the night before, but we had first pick of a bed in the smaller room. We found a waterfall a few hundred yards from the hut hidden in its little gorge and we stripped and showered away the ash that clung to our skin under the freezing spring fed torrent.

Our shower for the evening

We had a lazy start the next morning and after a breakfast of noodles washed down with coffee we cruised our short third day. The route continued east following the dried up rivulets through the ash desert, crossing huge lava ridges, which eventually plummeted down into the valley beyond.

Down in the valley pockets of forest have survived the bombardment from the 12 Tongariro vents nearby. Their cool interiors, moss and lichen rich, provided a refreshing refuge from the scorching sun.

The Waihohonu hut is only a few years old and a palace compared to our previous two nights.  We bathed in the nearby spring, which flowed from a small cave opening at a rather chilly 3 degrees. We also went duck spotting for the very rare Blue Duck or Whio, with Amanda the hut warden. She became very giddy at the sight of it, as it was only the second sighting of one in that area.  It is a rare duck, holding territories on fast flowing mountain rivers. We met a new friend at the hut, Julia a tailor from Germany, who had once done a language course in Llandudno and lived in Chester for a few months – small world!!



We reach the vegetation again

Our final day we cruised back to Whakapapa through ancient lava flows now covered in heather and grasses. The heather was introduced by a former Ranger of the Tongariro National Park, to encourage grouse and pheasant for shooting. Unfortunately this invasive plant out competes many native species of grasses and shrub and is now managed intensively by the Department of Conservation to minimise its spread.

We visited the old Waihohonu hut, one of the first built in the park, used by the victorian hikers and skiers. Their graffiti still remains, adorning walls doors and beds. Carvings have ben produced by those trapped in the hut by bad weather and a collection of old photos and artefacts dating back through to the 19th century are on display, including good old Oxo and Coleman’s mustard. It was a fantastic little time capsule of the Tongariro visitors over the past 150 years.

Crossing the saddle between Ruapehu, with its snow covered peaks, and Ngauruhoe we completed our circuit of Mount Doom, its perfect cinder cone had dominated the four days.

I think the emergency food rations haven't been updated for a while

Uh oh - last sweety!


Back at Whakapapa we celebrated our trek with a well deserved pint or two with Julia. The following day was intended as a rest day, so we climbed Mount Ruapehu, which wasn’t much of a break at 2797m! However, we decided to cheat a little and took a chair lift to 2000m. There are no marked tracks to its summit so we followed a line of best fit and scrambled to an obvious ridge line which we followed to the crater rim and had our lunch in the sun dappled snows of the summit.

Back to ‘The Shire’

Hobbiton is the home of ‘The Shire’, the set for the Lord of the Ring and the Hobbit movies. During the day, whilst the Hobbits are tending to their fields, muggles like us can visit the village and their homes – a real privilege.

We joined the crowds and went for a tour around Hobbiton village. The farmer must have had a real shock when Peter Jackson rang his doorbell and now he’s a millionaire, hosting one of the most popular tourist attractions in New Zealand.

The set had been constructed using temporary materials like Styrofoam and plastic for the Lord of the Rings trilogy, but was rebuilt using permanent materials for the Hobbit prequels. It was laid out with minute details that made it look so realistic, down to the moss and lichen on the picket fences and the peeling paintwork on doors and window frames. All the filming inside the Hobbit holes was undertaken in a studio as it would have been too dark to film in the hill.

It was interesting to learn how the sense of perspective was created to make Gandalf seem much taller than the Hobbits. This was achieved by sizing the background in different ratios, i.e. full height or 100% when the Hobbit character was next to a door (making the door look larger than the Hobbit in comparison) and a 60% scale door when Gandalf was standing next to the door (making the door look smaller than Gandalf in comparison). This approach was used throughout the films.

We toured the lanes, the tiny homes, the water mill and even sampled a stout in the Green Dragon Inn – thankfully at a 100% scale!

Bagend complete with artificial oak tree. The first tree was cut down from nearby and placed on top of the hill. Artificial leaves were then made (in Taiwan) and stuck on to the tree by hand. It was then decided they were the wrong colour and were each spray painted hours before filming began! For the Hobbit trilogy the tree was starting to fall apart so they made a mould of it and made this replica out of concrete. The end twigs however are from the original tree and the leaves were stuck on all over again!


Wahoo - i can see the pub from here!

On Yer Bike

Travelling south from the top of the North Island by bus we overnighted in the volcanic area of Rotorua. During our brief stop we explored by bike the eggy smelling town's mud pools, large crater lake, bubbling vents and steaming ponds.

We pedaled around on a three-hour tour, guided by a very knowledgeable local who told us a little about the history of the place. We discovered more about the Maori culture of this area and the problems faced when developing a spa business in the naturally corrosive waters. As geologists we found it fascinating to see that in an area the size of a tennis court, contrasting springs could occur, some boiling hot, some cold, some acidic, some alkaline. One environmental engineering design taken up in Rotorua, which could be applied worldwide, was the creation of a floating grassland island - the world's largest. This provides a nesting habitat for birds and natural filtration of the lake waters to improve its quality.


The tour was finished off with a game of bowls, which Chris displayed a natural talent for!

Wonderful carvings outside the Marae - Maori meeting house



Notice anything strange? The graves are raised - no burying of bodies at this church as its right over a hot water spring - you don't want to be digging up the place - the corpses would poach!!

One end of this small lake is fed by hot alkaline springs, at the other end it is fed by a cool fresh water spring. The fresh water is less dense so floats on the top allowing these wonderful algae to grow

Fresh meets caustic waters and the algae finishes

 The largest floating man made grassland in the world - its only a few hundred metres long


Warm (40C) lightly alkaline water - good for softening the skin

Sulphur crystals

A cold, fresh water spring, warm alkaline spring and a hot acidic spring all within a few metres of each other - incredible!

Remnants of victorian era baths set in the lake shore - they were intended to be filled by a lightly alkaline spring for softening the skin but unfortunately they chose the wrong spring and instead were filled with acidic water at pH1 - oops!

The old spa hotel and reigning world bowls champions from the UK!
