Los Gigantes Marina is the resort's practical centre, squeezed between the cliff-backed beach and the steep streets above. Excursion boats, sailing trips, diving operators, and whale-watching tours all work from here.
Even if you are not taking a boat, it is worth wandering down to the harbour. The scale of the cliffs is easier to grasp from the quay, and the marina cafes make a good low-effort stop after the climb back from the beach.
