Mercer Bay (Te Unuhanga-a-Rangitoto)
A clifftop loop with the whole coast underneath you and no way down to the water at all.

Probably the best hour of walking in Auckland. The loop runs along the cliff edge between Karekare and Piha, two hundred metres above a bay you can see perfectly and never reach. There is a pā site up here and the drops are unfenced in places. Go in clear weather and take the light seriously, because the walk out is exposed.
