The main hotel building and spa, housed in a white granite-covered block, sit alongside an iconic circular annex — nicknamed “the UFO” by locals for its spacecraft-like form — all with eclectic interiors designed by Italian designer Paola Navone. COMO’s great advantage is its location, set on a plateau between Sassolungo and other Alpe di Siusi peaks, with a vast expanse where guests can catch the sun rising over one toothy mountain and setting behind another.

Adler getaways are known for their generous, full-board stays and the excellent food and drink guests enjoy in abundance, but the spas deserve their plaudits, too. At Adler Lodge Ritten, saunas on stilts are tucked among the treetops, immersing visitors in the spectacle of the sweeping Alpine landscape. Add to that a cold plunge outside and an indoor-outdoor pool in the main structure, as well as cozy pinewood cottages clustered on the hillside around a lake.

A 1912 Habsburg sanatorium designed by Austrian architect Otto Wagner anchors the three newly built towers that host the hotel suites at Forestis Dolomites. Their angled geometry is a mirror to the mountain and endless pine forest setting of this uber-chic VIP getaway in the Dolomites. Accommodations celebrate larch timber and other essential elements of Alpine construction, while saunas with nature views and a steaming outdoor pool are designed for contemplating the landscape.

Designed by the onetime fashion designer Ilse Meister and inspired by Tyrolean tradition, the San Luis is a masterpiece of minimalist contemporary architecture. Inside the main lodge lies the spa complex — a soaring, candlelit pavilion of glass with an indoor heated pool that flows seamlessly into its outdoor extension. Outside, a clear pond centers the property and makes for great cold dips or ice skating, depending on the temperature.

The long-loved Rosa Alpina has been newly reimagined as an Aman hotel and a contemporary Alpine retreat by one of the world’s premier hotel architects, Jean-Michel Gathy. The structure incorporates pale wood, Dolomite rock and floor-to-ceiling glass walls to draw in the mountain panorama — and the resort is now open to families for the first time, but with a Zen simplicity designed to calm all comers.

Designed by Italian architects NOA in a daringly contemporary style, Hotel Hubertus is not afraid of heights. A 25-meter (82-foot) cantilevered Sky Pool extends out from the structure, suspended several stories above the grassy slope, with spectacular views from its heated waters. A sauna and whirlpool complex juts out from the hotel to hang midair like a bee’s nest, giving guests the sensation of floating free from the everyday world.

Made for mountain views, Milla Montis earned the DNA Paris Design Award for the architects of Milan’s Peter Pichler studio. Traditional Alpine pitched roofs top a structure in blackened wood opening to ultramodern terraces and big bubble-shaped windows — including in the sauna, which gazes out over mountain peaks. The spa’s hay room bathes visitors in the soothing scent of dried hay, and a creek on the property serves as a natural cold dip.

Another arresting contemporary project by the Peter Pichler studio, Schgaguler Hotel, set in the center of Castelrotto, transforms traditional Alpine lodge construction into a gleaming vision of glass and geometry, with unbroken views of the Dolomites and clean-lined interiors of chestnut wood and pale resin floors. The light-filled interiors are home to two heated pools and a pair of saunas, with a whirlpool on the outdoor terrace.

Overlooking the Dolomites from a mountainside above Merano, Castel Fragsburg sits beyond the UNESCO-protected range of cliffs. Architecturally, the small distance from the mountains manifests in the nostalgically romantic interiors of this former hunting lodge: It follows the elegant heritage of Merano more than the contemporary minimalism of the Dolomites, but the charm of the flower-patterned rooms and antique-framed beds makes it an irresistible base for exploring the area.
