Cave Stream Scenic Reserve, New Zealand
Cave Stream
Just down the road from Arthur's Pass lies a discrete little turning into a nature reserve car park. Venture down the path and you enter Cave Stream, a waist deep, freezing cold, underground river which winds its way through the hillside to emerge a kilometre or so upstream. The small plaque casually suggests that a headtorch and shoes might be helpful. A very cool little subterranean adventure.
