Glacial lakes, lush beech forest and snow-capped mountains have endowed Nelson Lakes National Park with a reputation for supreme beauty. Few, however, venture a short way over the St Arnaud Range, crossing the Rainbow Road into the Rainbow and Leatham conservation areas. These seldom-visited places hide beautiful bush-clad valleys with names like Hellfire and Misery, the valleys themselves being surrounded by the alpine wonderland of the Raglan Range. It’s a spectacular playground for adventure beyond the well-trodden trails over the hill.
The trip over the Rainbow began with waves washing over the bow of the Awatere, part of a ritual familiar to North Island trampers crossing Cook Strait to Te Waipounamu.
Our van bounced through the fords and potholes of the Rainbow Road towards the Wairau Swingbridge. By the time we’d parked and crossed the swingbridge, it was well and truly dark. Legions of stars marched across the sky and the moon illuminated our path down the river. It took about an hour to our campsite, near the confluence of Hellfire Stream.
The following morning, the stars had been replaced by dark clouds and the first order was crossing Hellfire Stream, before following the track that clings to the side of the valley. We were careful on the thin ribbon of trail, aware of the steep slide to the stream below. When the path wasn’t high above the stream, it was practically in it; requiring us to scale wet moss-covered boulders to continue. The cold bite of the water in our boots did little to dampen our spirits though: we were all pleased to have escaped Wellington for this primeval landscape.
The stream relaxed to a slow-moving lull and the dense forest gave way to clearings of stumpy tussock. After pushing through one final steep section to the bush edge, we stopped for lunch and were treated to spectacular views of the head of the valley. We all agreed there were much worse places to have lunch.
