Masca is a small village in the Teno massif in northwestern Tenerife, perched on a narrow ridge at 650 metres with ravines dropping away on both sides. The approach road from Buenavista del Norte is genuinely spectacular — a sequence of tight hairpin bends cut into vertical cliffs, with views of the Atlantic and the island of La Gomera. The village itself has a small museum, a few houses, and several restaurants.
Below Masca, the Barranco de Masca is one of the most dramatic gorge walks in the Canaries: a two-to-three hour descent through a narrow volcanic ravine to a small beach where a boat picks up walkers and takes them back to Los Gigantes. The walk requires good footwear, a head for heights, and a reservation for the boat. The gorge is periodically closed after heavy rain due to rockfall. The Los Gigantes cliffs visible from the coast — dark basalt walls dropping 600 metres to the sea — are best seen from the boat returning from the gorge.
