Back in late 90s/early 2000 I went to Tenerife and found a small beach/bay which I am trying to find on a map again for my visit in December 2008.
It was on the North coast (North West I believe). It had black sand (as many in Tenerife do). It was not commercialised at all , no sunbeds on the beach (it just had a couple of little cafes).
The main thing I remember is that it had a lerge rock in the sea with a pathway around it which I walked around. The pathway was linked to the promanade.
If anybody has any ideas what the name of this beach is/any photographs I would love to hear from you as I have spent many weeks trying to find out myself (unsuccesfully).
