The largest freshwater springs in Australasia and reputedly the clearest in the world, ‘Pupū Springs' is a colourful little lake refreshed with around 14,000L of water per second surging from underground vents. From Takaka, head 4km northwest on SH60 and follow the signs inland for 3km from Waitapu Bridge. There are illuminating information panels at the car park and a 30-minute forest loop taking in the waters, which are sacred and therefore off limits.
