Tenerife is the largest of the seven Canary Islands in
the Atlantic Ocean off the coast of Africa. Tenerife
has an area of 2034.38 square kilometers, and 886,033 inhabitants,
which make it the most populated island of the Canary Islands and
Spain.
Tenerife is a rugged and volcanic island sculpted by successive
eruptions throughout its history (the most recent was at Chinyero in
1909).
The coasts of Tenerife are typically rugged and steep, particularly
on the north of the island than in the south. However, the island
has 67.14 kilometers of beaches, surpassed only in this respect by
the island of Fuerteventura. On the northern coast are frequent
pebble beaches with black sand, while on the south and south-west
coast of the island, the beaches are typically much finer and
clearer with lighter tones and quality of sand.

Costa Adeje
In terms of beauty, Costa Adeje is a striking location with much
to offer in the way of black, glittering beaches of volcanic sand
and clear water that seems meant for scuba diving and snorkeling. If
you want to spend most of your holiday outside, Costa Adeje is one
of the best places in the Canary Islands to do so. Take advantage of
the whale-watching tours where you can watch whales and dolphins
swimming in their natural environment. You could spend weeks here
and not run out of outdoors activities. Whether your taste is more
for windsurfing, or you find you'd rather relax on a three hour boat
tour of the coast, you'll find plenty of options.
