What else can you find in an island that has almost 365 days of sunshine and mild temperatures, besides the museums and the "normal" places of interest? The beaches of course!
Tenerife has created some high quality, man made beaches, most of a fine black shingle or sand. These are mainly around the major tourist resorts. Most have good access, meet stringent European standards of cleanliness and most offer shower facilities, sun beds, shades and water-sports.
