Highlights

What to see

Tre Cime di Lavaredo

Three towering peaks that define the range, ringed by trails and mountain rifugi in every direction.

Lago di Braies

An emerald lake cradled by sheer dolomite walls, among the range's most photographed corners.

Sella Massif & Passes

The Sella group anchors legendary circuits like the Sella Ronda and the high passes around it.

Hours

The mountains are always open; cable cars and rifugi keep seasonal hours, typically spring through early autumn

Entry Fee

Entry to the mountain areas is free; lifts, cable cars, and mountain passes charge per ride or toll

Best Time

June through September for hiking, and December through March for skiing at resorts like Cortina

Nearby Sites

Cortina d'Ampezzo, Sella Ronda, Lago di Braies, Val Gardena, Marmolada Glacier

Conservation

Preserving the site

Erosion, climate change, and visitor pressure along the busiest trails strain the fragile alpine landscape. Park management, trail maintenance, and careful zoning help balance tourism with protection. Italy's natural sites all remain off the List in Danger.

Make the most of your visit

  • Book rifugio beds months ahead for popular routes like the Tre Cime circuit

  • Rent a car to tackle the Dolomite passes at your own pace, or join a guided tour

  • Pack layers — weather shifts quickly at altitude, even in summer

  • Try the Sella Ronda, a lift-served loop that suits skiers and cyclists alike

Protect your trip

Mountain trips carry real risk — weather changes fast, lifts get canceled, and hiking injuries happen far from help. Travel insurance with coverage for altitude and outdoor activities can make all the difference.
