Stays with Heated Pools in the Dolomites, Open All Winter

From the adults-only rooftop infinity pool at the Majestic, the water runs out towards green fields, the Puster Valley and the mountains beyond. Below it are four more pools: a heated outdoor pool, an indoor pool with a water slide, an indoor kids' pool, and the main indoor pool among stone columns, which is heated, free, open all year and open to all ages.

Around them stretch 1,200 m² of wellness space, with a wide range of saunas and steam baths, and heated water beds in the relaxation area, where fruit juices and herbal teas are set out. The outdoor pool is kept at 32°C all year and the indoor pool at 30°C, both open daily from 8:00 to 20:00, so a January swim works either way. The kids' pool and slide are indoors; the 25 m roof pool is for grown-ups.

Kolfuschgerhof has two pools. The indoor pool is 14 m long and kept between 26 and 30°C, with a ledge to rest on, and the rooftop infinity pool outside, 12 x 5 m and heated, looks out over snow-laden trees, timber chalet walls and the rock faces of the Dolomites. Both are free to use, open all year and open to all ages, and in summer the same water sits between green lawns and grey peaks.

Wellness here goes well beyond the pools: sauna, steam room, hammam, hot tubs, an open-air bath, a foot bath, light therapy and a relaxation lounge, with yoga classes too, and some suites have their own hot tub and sauna. For a January swim, the heated indoor pool is the sure thing, with the rooftop pool for a steaming dip in the cold air.

Up on the roof of La Cort's spa, the infinity pool's glass edge drops away to the meadows and villages of Val Gardena, with the valley town below and peaks lined up beyond. It's outdoors, heated and open all year, so the view swaps green summer slopes for snow while the swim stays the same.

The Rooftop SPA around the pool has three saunas, a steam room, a hammam and an open-air bath, with loungers and towels ready on the deck and free swimming within set opening times. With adults only and a minimum check-in age of 18, it's a pool for grown-ups: a swim before breakfast, then the saunas after a day on the Ortisei cable cars.

Arched windows and white columns line Kastel's indoor pool, with a painted mural running the length of one wall. The water is kept at about 30°C, there's a water jet and a whirlpool at the edge, and the pool is open all year. Children get two adventure pools of their own, with pool toys and a water slide.

Around it, the spa adds a Finnish sauna, a bio sauna, an aroma steam room and a rock grotto with a small saltwater pool, all free for guests and open through the day. It suits families best: after a winter day on the Alpe di Siusi slopes, this is warm water at 1,100 m that small children can enjoy as much as you do.

In Valdaora, this family-run aparthotel has four pools to choose from. The everyday one is indoors: heated, open all year and free, with a raised stone surround, a shallow end and a round lit panel in the ceiling above. Children have their own indoor pool with toys, there's a fourth indoor pool, and outside, behind a fence, an infinity pool kept for adults looks across the lawn to the mountains.

The spa wraps around them with a hot tub, a sauna, a steam room, a hammam, a foot bath and a relaxation area, and the pools keep set opening times. Families do best on the indoor side, where all ages are welcome. For a January swim, count on the indoor pool: the outdoor infinity pool isn't confirmed as heated or open in winter.
