Tenerife is really two islands — the volcano and laurel forest in the north, the water parks and whale boats in the south — with about an hour's drive between them, so either base reaches both.
Teide National Park and the cable car
Spain's highest mountain at 3,718 m, reached by road across the caldera and then by cable car; online cable-car tickets start around €24. The last stretch to the actual summit is a separate permitted path booked well in advance, and since January 2026 some time slots on it carry a fee. The crater rim is cold and exposed year-round — bring layers whatever the coast is doing.
Siam Park
Water park at Costa Adeje, open daily 10:00–18:00 from 1 May to 29 October and 10:00–17:00 the rest of the year. Tickets are sold through the park's own online system, and it is the most expensive single day out on the island.
Whale and dolphin watching off the south coast
Short-finned pilot whales and bottlenose dolphins live year-round in the channel between Tenerife and La Gomera, so two- to three-hour boat trips from Los Cristianos, Puerto Colón and Los Gigantes have a high hit rate. Choose an operator carrying the whale-watching authorisation required by the Canary Islands government, and take the morning sailing before the wind gets up.
Anaga Rural Park and Playa de Benijo
Laurel forest on the ridge above Santa Cruz, a UNESCO biosphere reserve, with marked trails and roads that take far longer than the map suggests. The walk down to the black-sand beaches at Benijo and Almáciga is the standard half-day; the Cabildo's own nature portal holds the trail descriptions and any closures.
San Cristóbal de La Laguna old town
A UNESCO World Heritage site for its unwalled grid plan, the template the Spanish then used for colonial cities in the Americas. It is a working university town rather than a preserved one, flat and walkable in an afternoon, and the tram from Santa Cruz drops you at the edge of it.
