The 2800 average hours of yearly sunshine mean that the beaches are the star turn here, but if you just can peel yourself away from your sunbed, you'll find there are bundles of other energetic options.
The volcanic coast here makes for some superb diving, and calm waters mean that even a first-timer can have a thrilling ‘try dive’ in the ocean (and take it from there). A standard dive runs upwards of €35; per-dive rates drop if you’re planning several days of diving. There are several outfits to choose from.
You won’t have to sail far from shore before the hotel jungle of Tenerife’s largest resorts are dwarfed by the vast volcanic bulk of the island. Hire a boat, take an excursion or sign up for a whale-watching trip and cruise the waters between Tenerife and La Gomera with the beautiful outline of El Teide behind you. The tourist office in Los Cristianos has a list of companies that organise all manner of boat trips.
Chartering boats is also a popular choice, especially for groups; contact Tenerife Sailing Charters, based in Costa Adeje.
Note that although there are several places that offer horse riding, not all are accredited and safe.
Constant mild weather means that Tenerife is a place where golfers can play year-round. It’s not the most ecologically sound activity on the island (water is a constant problem, and golf courses are very thirsty), but that hasn’t stopped sprawling courses from emerging all around Playa de las Américas.
Companies offering two-, three- and five-hour boat cruises to view whales and dolphins operate from the end of Playa de Los Cristianos, near the port, and in Puerto Colón in Costa Adeje. Most trips include food, drink and a quick swim. There are several such companies but all are basically the same, with a two-hour trip costing upwards of €18.
Deep-sea-fishing jaunts for tuna, swordfish and other species of fish start at about €49 for a three-hour trip. Get information from the kiosks set up at the western end of Playa de Los Cristianos or from tourist offices.
The best-known surf spot in town is the creatively named La Izquierda (Spanish for 'Left'), which is found just west of Playa de Troyo. A long and easy left with some hollow sections, it’s one of the most localised spots in Europe.
