Just bumping this up, it doesn't look very promising so far!!

Arkwright

Last time we were in Tenerife (a little over 2 years ago) we bought a hiking map of the island and there was a short walk north from La Caleta to El Puertito which we undertook. This is a pleasant footpath walk along the clifftop and following the coast; about 3km in total each way with a little bar/restaurant at El Puertito where we had lunch. The first beach you encounter north from El Caleta is not much more than a rocky cove and was marked on our map as "Hippy Valley". However further on from this is a nice sandy beach (not named on the map) which you can scramble down to from the footpath. We stopped there on the return journey and there was a good mix of naturists and textiles. We will definitely go again next time we are on Tenerife.
