The Steaming Earth - around Taupo and Rotorua

Waimangu Warbrick Terrace

New Zealand is a volatile country—earthquakes shake us.  In the past volcanoes blasted the landscape and the earth simmers still, spitting boiling mud from bubbling pools and heating the water for those hot pools we love to soak in.  Lake Taupō was formed by a volcano 27,000 years ago.  It last erupted in AD 181, turning the skies red over China and Rome.  The caldera is now New Zealand's largest lake, with a surface area of 616 square kilometres.  Lake Rotorua was formed in another caldera, its volcano erupted 200,000 years ago.  Mount Tarawera last erupted in 1886, altering Lake Tarawera, the Blue and Green Lakes (and other smaller ones) burying the Māori village of Te Wairoa, and destroying the famous pink and white terraces.
            These silica terraces were at the time New Zealand's premier tourist attraction, a series of beautiful pools where people could bathe, the silica looking like frozen waterfalls between one pool and the next.  They look so stunningly beautiful in paintings and photographs from the time that I deeply regret their loss.  The eruption caused the deaths of about 120 people and altered the surrounding landscape, dumping tonnes of ash and debris over the area.  We found out a lot about the eruption at the Buried Village Museum which is on the road from Rotorua to Lake Tarawera.  This is a combination of museum, archaeological site and reconstruction, set in twelve acres of park-like grounds.
Waimangu Volcanic Valley
Waimangu Volcanic Valley, a little further south, was formed by the Tarawera eruption of 1886.  We walked for two hours through this amazing steaming and bubbling wonderland (taking a shuttle bus back to the visitors centre) discovering many features that illustrate the geothermal activity of the area.  There were pools, both hot and cold, coloured shades of blue, green and even red.  Hot springs bubbled up to the surface of Frying Pan Lake, causing strange sounds to echo around, while steam drifted up past the Cathedral Rocks behind.  These were completely changed in shape after the Frying Pan Flat eruption of 1917 which killed two people.  There are silica terraces that must be similar to the pink and white terraces, though on a smaller scale.  Ripple terraces are forming beside the original ones.  At the end of the walk we rested beside the shores of Lake Rotomahana, where boat cruises are available.
St Faith's Church, Rotorua

            Rotorua itself is a city built on geothermal activity.  Kuirau Park near the city centre is an area of thermal springs which can be strolled around in an hour.  On the lakeside itself we always love walking around to Ohinemutu, once the main centre for the Rotorua region.  The village was chosen because of its setting and because of the hot springs which Māori used for cooking and washing.  We first walked there one still evening and were soon shrouded by steam which gave the place an eerie feel.  No one was about but there were two carved meeting houses and a church.  It was as if we had stepped out of time.  The church was St Faith's, built in 1914.  The impressive interior is rich with carving and woven panels while a window is etched with the figure of a Māori Jesus, who appears to walk on the waters of the lake.
We headed to the Polynesian Spa hot pool complex beside Lake Rotorua where we took the waters, as visitors have been doing since 1878.  From the pools we had views over the lake.  Our muscles were relieved by the acidic water from the Priest Spring and we were promised ageless beauty as we relaxed in mineral rich waters of the Rachel Spring.  This complex is one of the more expensive and luxurious we have visited a contrast to places like homely Ngawha Springs in the north and tiny Morere Springs that we would visit later.
Hamurana Springs

            Springs of a different sort are found on Lake Rotorua's northern shores.  We followed the Hamurana Springs track through a forest of towering Redwoods (planted in 1919) before coming to New Zealand's deepest natural fresh water spring.  The crystal clear water that rises up into the pools here has been underwater for 70 years.  The main spring is called Te Puna-a-Hangarua and we saw lots of coins sparkling from the bottom.  Throwing coins into the spring is an old tradition, and back in 1957 divers recovered more than 5,000 pennies which were donated to charity.
            State Highway 30 took us west to Kawerau.  Built in the 1950s as a mill town, the town site was chosen because of its proximity to the Kaingaroa Forest and the readily available geothermal energy.  Now the little town encourages freedom camping in self contained vehicles like ours.  Not only can people park up for seven nights at various places in the town but Prideaux Park, where we stayed, has free power available.  Even better, just over the fence were the free, thermally heated pools where we had a few soaks.  These pools were a million miles from the sophisticated Polynesian Spa experience.  Here local families splashed around and had noisy fun.  It was an honest-to-goodness kiwi experience.   
On the Tarawera falls Track

            We wanted to visit Tarawera Falls near Lake Tarawera.  Described as the most spectacular falls in the Bay of Plenty, the waterfall is formed by a river plunging 65 metres down a sheer cliff face before separating into many smaller cascades.  Accordingly we went to an office in Kawerau for a forest access permit, and then drove Tangaroa along the 27 kilometres of forestry road to the DOC camp on the shores of the lake. 
            The walk started here at the Tarawera Outlet and followed the river through native bush for five kilometres, about one and a half-hours walking.  There were several very pretty rapids and waterfalls, also a tempting shady swimming hole, but the Tarawera Falls themselves were a disappointment.  It had been a dry summer and the cascade we had seen in pictures was not in evidence.  Water gushed from lower down and it was a picturesque scene—just not the dramatic one we had hoped for.  Back at the camp ground we decided the place was too dark and gloomy, so we drove Tangaroa all the way back to Kawerau and parked at the spot we'd left that morning.  In retrospect, we should have gone in the car—especially as the forestry road had been very muddy and Malcolm had to wash the bus and car on our return.  We were glad of those hot pools after the day's exercise.
On the Tarawera Falls Track

            Back in the Rotorua area we walked a circuit around the Blue Lake.  This is so named because it looks a turquoise colour, due to light reflecting off pumice on its bottom.  Two thirds of the walk is through native bush and the track passes the Green Lake which has a shallow sandy bottom making the water looks green.

            Then we took the road to Taupō.  Although it was tempting to stop at the hot pools in the Waikite Valley—we have been there before of course—we continued on and freedom camped beside the lake near Taupō town centre.  From here we went to DeBretts Hot Springs, another of New Zealand's earliest hot pool facilities.  First discovered by Sir William Fox in 1874, the present pool complex was created in 1958 and modernised in 1987.  Now it is part of a holiday resort with accommodation and camping, though the pools themselves, accessed down a steep driveway, feel private and secluded.
DeBretts Hot Springss

            There is a cycle route that goes right around Lake Taupō—we know because we have taken part in the Lake Taupō Cycle Challenge.  One year we did it as part of a four-person team, another year Malcolm cycled it as an individual.  We weren't planning on cycling this time though because we had a walk in mind: the Tongariro Crossing.  We had set out to do this walk before, but when we got as far as Mt Ngauruhoe—famous to Lord of the Rings fans as Mt Doom—decided to climb to the summit.  It was a clear, sunny day and we knew we would have magnificent views, which we did, right across to Mt Egmont Taranaki, 180 kilometres away. 
On the Tongariro Crossing



When, on a previous occasion, Malcolm walked the Tongariro Crossing, he had pulled in an ascent of Ngauruhoe as a side trip.  I'm sure he could have done so this time too.  However I am always slow on steep up-hills, and found the scree slopes very difficult as I kept slithering backwards.  The outcrops of sharp volcanic rock were awkward to get across too so, after enjoying the views and eating our picnic lunch, we descended and walked back along the track to Whakapapa Village.  This had been a seven hour walk in itself, so on the way back to Taupō we stopped for a relaxing soak at the Tokaanu thermal pools—a basic but peaceful place near the southern tip of Lake Taupō.
            I successfully completed the next crossing attempt with Malcolm and  small group of friends.  We met up at Whakapapa and began the crossing, which took around seven hours.  The first section went through the Mangatepopo Valley, scoured out in the ice age and partially  in-filled by lava from Mt Ngauruhoe.  After about one and a half hours the track began to climb steadily and steeply, giving great views back down the valley.  A poled route lead us across South Crater to a ridge, then up to Red Crater, the highest point on the crossing.  From here it was a short walk down to the Emerald Lakes where we ate lunch.  The lakes' colour is derived from minerals seeping into the water from nearby thermal areas.  We looked across at Ngauruhoe, recalling our previous climb, then turned to continue our tramp.
            I had pulled on warm gear and a windproof coat by now as—even though it had been hot work climbing up to the Emerald Lakes—it was very cold here with a blustery wind.  I had been warned that it could get icy at 1,700 metres above sea level and was glad of the warm clothes.  We continued along the next section of the track from Central Crater to the Blue Lake which is a freshwater lake in an old lava vent.  Like the Emerald Lakes, dissolved minerals give the Blue Lake its distinctive colour.  The lake's Māori name is Te Wai-whakaata-o-te-Rangihiroa (Rangihiroa's Mirror) and it is tapu (sacred).  Rangihiroa was said to have explored the volcanic plateau around AD1750.

Amazing views on the walk

            The next section of track skirted the edge of the North Crater, then we began the descent.  We stopped for a coffee break and snack by the Ketetahi Hut, before continuing through podocarp forest to the road end car park.  The Tongariro Crossing is one of New Zealand's greatest day walks and I can see why—it was an unforgettable experience.
            There was only one thing left to do—check out the new hot pools at Taupō's Wairakei Terraces.  The pools here nestle beneath silica terraces—reminiscent of the pink and white terraces.  As we soaked amongst the steam and silica we thought if we couldn't visit the terraces of bygone days, this was probably the next best thing.
