Stays with Heated Pools in Tenerife, Open All Winter

Four outdoor pools wind through palms and dark volcanic rock here, and the one to head for is the main infinity pool: saltwater, heated and open all year, its edge running out towards the Atlantic. It has a shallow end, a pool bar within reach and pool toys for younger swimmers. Around it sit a kids' pool with a plunge pool, a third pool for all ages, a fourth with set opening times and a water slide.

Expect loungers, umbrellas and towels at no charge, plus a sauna, a hammam and massages. The kids' club and playground make this an easy family pick. One thing worth knowing for winter: heating is confirmed for the infinity pool, the kids' pool and the two pools of the slide and play area (24°C in winter), but not stated for the third pool, so check before you promise everyone a January swim.

Palm trees and a Thai-style pavilion frame the main pool at the Botánico, set in large gardens with views of the Atlantic and Mount Teide. It's outdoors, heated to 26°C and open all year, ringed with red parasols and loungers, and it's the pool everyone can use. A kids' pool with a plunge pool sits nearby, and a third outdoor pool is kept for adults, with set opening times.

Inside, the 3,500 m² spa has its own heated pool under a timber roof, along with Turkish baths and a Japanese sauna, and access is free for guests aged 16 and over. Towels, loungers and umbrellas come with the outdoor pools at no charge. Children of any age are welcome at the hotel, so the main pool is where families swim, while the spa stays a grown-up space.

From high up in Torviscas Alto, the main pool looks down over the rooftops of Costa Adeje to the Atlantic, its curved edge set into a pale stone terrace with palms and canopied daybeds around it. It's outdoors, heated and open all year, with a shallow end, a plunge pool and a separate kids' pool alongside.

Loungers, parasols and pool towels are free to use, so a day here can run from a morning swim to sunset over the lights of the coast. Children of all ages are welcome, and the complex keeps quiet hours from 22:00 to 09:00. With a kitchen in every apartment, it suits families and longer self-catering stays through the winter.

The Atlantic fills the view from the rooftop infinity pool at Royal Hideaway, its edge lining up with the sea, with daybeds set on platforms in the water and a timber deck all around. Below, in front of the white terraced facade, the main outdoor pool sits among lawns. Both outdoor pools are saltwater, heated and open all year, with loungers, umbrellas, and pool and beach towels.

No children stay here, so there are no kids' pools, and the rhythm is set by adults. Away from the outdoor water, the spa adds a third heated pool, a hydrotherapy circuit with jets and waterfalls, a steam bath and a sauna.

On Abama's clifftop, three heated pools are open to every guest all year, out of seven spread through the gardens. The Lagoon Pool, the largest, curves between palms at the heart of the Citadel. The Persian Garden Pool sits among the terracotta, Moorish-style buildings looking over Abama bay, and the Serenity Pool, for ages 13 and up, faces the golf course.

Loungers, umbrellas and towels are set out at each, with lifeguards on duty and the pools open from morning until 18:00. Children are welcome at the Lagoon and the Persian Garden; Serenity keeps its afternoons quieter for 13 and over. Here's the thing: the Del Mar infinity pool and the villa-area pools are kept for Retreat guests, so book the Retreat if a sunset swim over the bay is the point of your trip.

A broad, many-sided outdoor pool fills the middle of RIU Garoé's 2,800 m² tropical garden, with the hotel's wings wrapped around it. It's open all year and heated in winter, and a fenced kids' pool sits alongside it.

Loungers, parasols and pool towels are included, and the pool bar is a few steps from your lounger. For cooler evenings, the spa has a sauna, steam room and hot tub, plus massages and beauty treatments. Children of any age are welcome, with a playground and mini golf in the grounds, so this one suits families as much as couples looking for winter sun on the north coast.

At the centre of Flamingo Suites, the pool sits on a pale tiled sun terrace, with curved white buildings and tall windows facing in on it from every side. It's outdoors, heated and open all year, with a plunge pool and a kids' pool alongside, and La Pinta Beach is only 100 metres away when you fancy the sea instead.

Pool access is free within set opening times, with loungers, umbrellas and towels provided, and the spa has a hot tub, a sauna and a steam room for slower afternoons. Children of any age are welcome, so expect families around the main pool. The 1- and 2-Bedroom Suites with Private Pool have their own heated pool on the terrace, so a winter dip works there too.

White hotel blocks wrap around a curving pool at Coral Suites, with terracotta paving, palms at the edges and a poolside bar close at hand. It's outdoors, heated and open all year, with a shallow end for easing in, and the Nuevo restaurant looks straight over the water.

Because the whole hotel is adults only, with a minimum check-in age of 18, the pool stays a grown-up place from breakfast to the last cocktail. Loungers, umbrellas, and pool and beach towels are all provided, and swimming is free. When you want a change of view, head up to the rooftop terrace for the Atlantic, or into the spa. A good pick for winter sun without children.
