You arrive in Ortisei in the second week of May expecting green meadows, open huts, and a clear path to Seceda. Instead, the valley is warm, the peaks still carry heavy snow, and a trail sign sends you toward a closed lift. This is normal for the Dolomites in late spring.
May is a valley-hiking month first and a high-alpine hiking month only when conditions allow. Lower forest paths, lakeside circuits, and sunny plateaus can offer excellent walking. High passes, exposed ridges, cable-car routes, and mountain huts often remain limited. The best plan uses a flexible route list and checks the final conditions locally.
Which Dolomites trails are usually open in May?
The most reliable May walks sit below the lingering snow line or start directly from a village. A trail can appear on an official map and still have snow, ice, fallen branches, or a closed hut. Treat the word open as a starting point, not a safety guarantee.
Best early-season areas
| Area or trail | May outlook | What to check |
|---|---|---|
| Lago di Braies circuit | Usually one of the safer scenic choices from May | Ice on shaded sections, wind, boat-house and café hours |
| Val Gardena valley paths | Many lower paths work well, especially around Ortisei and Santa Cristina | Mud, snow patches above the villages, local closures |
| Alpe di Siusi lower walks | Often accessible, with the broad plateau opening earlier than steep peaks | Lift or road access, snow on north-facing tracks |
| Adolf Munkel Trail | Possible in May, but conditions can change quickly near 2,000 metres | Trail status, snow depth, open huts, return transport |
| Tre Cime loop | Conditional rather than dependable | Road to Rifugio Auronzo, snow, wind, parking, refuge opening |
Lift dates change the route list
For 2026, Val Gardena publishes several useful early openings. The Ortisei–Alpe di Siusi gondola and Marinzen lift are listed from May 1. The Resciesa funicular is listed from May 16, while the Ortisei–Furnes, Furnes–Seceda, and Col Raiser lifts are listed from May 22. The Forcella Sassolungo lift begins later, on May 30. Alta Badia’s main summer lift network starts in June, so May visitors should not build a plan around lift access there.
My clear pick for a first May hiking base is Val Gardena, because it offers more early-season lift options and several valley routes when the upper mountains remain snowy. Lago di Braies is the better choice for a short scenic trip with less elevation gain.
Why high Dolomite trails stay snowy in late spring
May weather feels like spring in the villages but can still resemble winter above 2,000 metres. The Dolomites rise sharply from valley floors, so a sunny breakfast in Canazei does not tell you much about the trail around a high mountain pass. Snow collects on north-facing slopes, in gullies, beneath rock walls, and on narrow ledges where wind packs it hard.
Elevation matters more than the calendar
Many popular viewpoints sit between 2,000 and 2,500 metres. In May, the final kilometre can change from dry gravel to hard snow. A snowfield may look short from a distance but cross a steep slope above rocks. Without traction and route-finding skills, that section can turn a simple walk into a slip hazard.
Use the tree line as a practical dividing mark. Forest trails and sunny meadows often dry first. Open plateaus follow. High passes and shaded cirques come last. A route that gains 700 metres from a village may also move through three different seasons.
Huts and lifts are part of trail access
Mountain huts do more than provide lunch. They supply water, toilets, shelter, local information, and a reliable point where hikers can turn around. In May, many do not open until late May or June. A route described as a four-hour hut walk can become a six-hour outing when you carry all food and descend on foot because the lift has stopped running.
Check three separate items before leaving: the trail condition, the lift or road operating date, and the hut opening date. None of these guarantees the others. The official Val Gardena route database lists the Adolf Munkel route as open and gives it as 11.9 kilometres, about 3 hours 36 minutes, with 280 metres of ascent and a high point of 2,165 metres. That information still needs a same-day snow and transport check.
The safest May rule is simple: choose the lowest route that still gives you the view you want. You lose some summit altitude but gain better footing, more daylight margin, and a stronger backup plan.
How to choose a May hike by week and weather
Do not create one perfect itinerary. Create three route tiers and select from them after checking the forecast and local trail reports. This approach gives you a real answer when a high trail closes overnight.
Use this three-tier decision system
- Tier one: valley and lake walks. Choose these for the first half of May, after rain, or when overnight temperatures fall below freezing. Good examples include the Lago di Braies circuit, village-to-village paths around Val Gardena, and lower walks near Castelrotto.
- Tier two: open plateaus. Move to Alpe di Siusi or similar broad alpine pastures when the trail report is good and the snow looks firm. Start early, carry a warm layer, and avoid isolated tracks that cross steep shaded slopes.
- Tier three: high routes. Attempt Adolf Munkel, Seceda approaches, Tre Cime, or high-pass walks only after checking snow, transport, and refuge conditions. A clear webcam does not prove that the trail is safe around every bend.
Match the route to the day
After a warm, dry week, a south-facing route may be excellent by late May. After a cold storm, the same path may need winter equipment. Morning starts help with firm snow, but hard snow can become slippery before it softens. Afternoon starts offer warmer ground but leave less time for a slow descent.
Keep one low route ready
My strongest planning recommendation is to reserve one complete backup near your accommodation. Do not choose a backup that still requires a closed gondola or mountain road. If the weather turns, a marked forest or lakeside route lets you hike instead of spending the day driving between closed trailheads.
What to pack for May hiking in the Dolomites
My gear verdict: use waterproof mid-height shoes, poles, a real rain shell, and a navigation backup. Lightweight summer trainers make sense on dry valley paths, but they leave little margin on wet stone, mud, and old snow.
Footwear and traction
Neither shoe replaces crampons or mountain boots on steep frozen snow. If your route crosses hard snow, ask a local guide or outdoor shop about traction before setting out.
Rain, wind, and temperature changes
Add a fleece or light insulated jacket, gloves, and a hat. May mornings can feel cold at the lift station even when the valley forecast shows mild temperatures. Pack sunglasses and sunscreen too; snow reflection can burn exposed skin quickly.
Navigation and walking support
Download offline maps before leaving your accommodation, save the last lift time, and carry enough food to stay out longer than planned.
Skip specialist high-alpine gear when you will walk only paved lakeside paths. Spend that money on transport flexibility instead. The best May kit matches the route you will actually hike, not the most dramatic route shown in a brochure.
May Dolomites hiking questions answered
Can you hike Seceda in May?
Yes, but access changes through the month. The Seceda lifts are listed to open on May 22, 2026, while the trail itself may hold snow above the tree line. Before the lifts open, reaching Seceda on foot creates a much longer and harder day. Use a current lift timetable, check the trail report, and confirm hut openings before choosing the route.
Is the Tre Cime loop open in May?
It can be, but it is not a dependable early-May plan. The road to Rifugio Auronzo, parking arrangements, snow, wind, and refuge services all affect the outing. Ask the local tourist office or mountain operator for the current access position before driving there. If the road or loop remains closed, choose Lago di Braies or a lower Val Gardena route instead.
Are mountain huts open in May?
Some lower huts and restaurants open during the transition into summer, while many high huts wait until late May or June. Never plan a full-day hike around an assumed lunch stop. Carry food and water, check the exact opening date, and keep enough time to return without relying on a final lift.
May rewards hikers who leave room for change. As the season moves forward, more lifts, huts, and high routes will open, but the Dolomites will still favor careful local checks over a fixed online itinerary.
