A relatively new resort on the southwest coast of Tenerife is called Playa Paraiso, and is really a very pleasant and peaceful holiday area. It has been built a lot of new hotels here, and the resort have hotels in relative high standard. The hotel Bahia Principe is a good example of this, a huge hotel with a lot of activities and a great swimming pool.
The old fisherman village Callao Salvaje is located about three kilometers away from Playa Paraiso, and is a nice excursion if you want to enjoy a great meal one evening, in one of the nice restaurants. Here you should eat one of the fishdishes, as they always serve fresh fish from the Atlantic Ocean. This is maybe one of the best areas in Tenerife for eating fish.
One thing to be aware of if you like to swim in the ocean, is that the beach here in Playa Paraiso is not much to talk about. It is a relatively small black lava beach, but there is a large saltwater pool called Lago Lido, where you can enjoy lazy days on Tenerife. Even though the beach is not that great, it's still quite ok for relaxing and getting a tan.
The resort of Playa Paraiso is located almost midway between Playa de San Juan on the west side, and perhaps the more famous resorts of Playa de Las Americas and Los Christianos on the east side. The golf area of Golf Costa Adeje is only minutes away by car, where you'll find both a 18-hole and one 9-hole golf course. From Playa Paraiso you also have a great view of the neighboring island of La Gomera. Enjoy your holiday on Tenerife!
