Dolomites in May: Weather, Trail Access & Early-Season Expectations

May in the Dolomites is beautiful but different from the summer hiking season most people imagine. High-altitude trails remain snow-covered, mountain rifugios are mostly closed, and weather is unpredictable. But that doesn't mean May is off-limits—it just requires different expectations.

If you're thinking about visiting the Dolomites in May, here's what you need to know: focus on lower-elevation valley hikes, expect spring conditions rather than summer weather, and plan for inn-to-inn hiking instead of high rifugio treks. For those willing to embrace early season, May offers peaceful trails, spring landscapes awakening, and virtually no crowds.

Weather in the Dolomites in May

• Temperature ranges: Valley floors (1,200-1,500m elevation) see daytime highs of 10-18°C (50-64°F), with nights dropping near or below freezing. Higher elevations remain significantly colder—anywhere above 2,000m still experiences winter conditions with frequent snow.

• Weather patterns: May is genuinely unpredictable. You might get three sunny days followed by two days of rain and snow. Multi-day storm systems still roll through regularly, and weather windows are less reliable than June-September. Early May feels more like late winter; late May begins transitioning toward summer.

• What you'll see: Spring awakening in the valleys—fresh green grass, early wildflowers emerging, and snowmelt feeding streams and waterfalls to their maximum flow. The landscape feels alive with water. Higher elevations remain white and wintry, creating striking contrasts when viewed from accessible valley trails.

• Daylight hours: May offers 13-14 hours of daylight, shorter than peak summer (15+ hours in June-July) but still plenty for full hiking days.

• The reality: May is a transition month—not quite winter, not quite summer. High-altitude Dolomites hiking as most people imagine it isn't really accessible yet, but lower-elevation routes offer beautiful spring hiking for those with the right expectations.

Trail Conditions & What's Open in May

Rifugio status: Most mountain rifugios remain closed throughout May. A few valley-level huts might open in the final week of the month, but the vast majority don't open until early-to-mid June. This means traditional hut-to-hut trekking isn't possible.

However, valley-level accommodations—guesthouses, hotels, inns—are open and fully operational. For details on when specific rifugios open, see our complete rifugios guide.

Trail Accessibility Breakdown:

1. Accessible

Lower valley trails between 1,200-1,800m elevation are usually snow-free by mid-to-late May. These include valley floor walks, forested trails, and routes around plateau areas like Alpe di Siusi (Seiser Alm).

2. Difficult or dangerous

High passes, exposed ridges, and anything above 2,000m remain snow-covered and require winter mountaineering skills, equipment, and avalanche awareness. Don't attempt these without proper experience and gear.

3. Impassable

Classic high-altitude routes like Alta Via 1, Alta Via 2, and passes above 2,500m are buried under meters of snow and completely inaccessible for normal hiking.

Snow conditions: Expect significant, consolidated snow above 2,000m. What looks like a well-marked trail on summer maps is often invisible beneath deep snowpack in May. Navigation becomes difficult and potentially dangerous.

Avalanche risk: Real and present on steep slopes where snowpack is actively melting and destabilizing. This isn't theoretical—May avalanches happen regularly in the Dolomites.

Bottom line: May works for lower-elevation inn-to-inn hiking where you stay in valley guesthouses rather than high mountain rifugios. Adjust your expectations accordingly, and you'll have a wonderful early-season experience.

Best Tours for the Dolomites in May

While high-altitude rifugio treks aren't accessible in May, several lower-elevation tours work beautifully during the early season. These routes focus on valley-level trails, use comfortable guesthouse accommodations, and showcase spring landscapes without requiring access to snow-covered high passes.

1. Dolomites Inn-to-Inn Hiking Tour (7 days)

Perfect for May because this tour focuses on valley-level trails between 1,200-1,600m elevation with comfortable guesthouse accommodations rather than high mountain rifugios. You'll hike through awakening spring landscapes, see waterfalls at their most powerful from snowmelt, and experience the Dolomites without summer crowds.

The route explores classic Dolomite valleys—Seiser Alm plateau, Val Gardena, and surrounding areas—staying below the snowline while still delivering spectacular mountain views. Daily stages range from 4-6 hours of hiking, and you'll stay in family-run guesthouses and small hotels with hot showers, real beds, and excellent food.

• Duration: 7 days

• Technical: 3/5 | Fitness: 3/5

• Why it works in May: Stays below snowline, uses valley accommodations that are open year-round, flexible routing if weather turns challenging

2. Alpe di Siusi Inn to Inn Hiking Dolomites (7 days)

Europe's largest high-alpine meadow (Seiser Alm / Alpe di Siusi) at approximately 1,800m elevation is usually accessible by late May. This tour focuses on gentle, rolling plateau terrain with spectacular views of surrounding peaks—the Sassolungo (Langkofel), Sasso Piatto, and Sciliar massifs rise dramatically from the meadow edges.

What makes Alpe di Siusi ideal for May is its relatively moderate elevation and gentle terrain. While higher passes remain snow-covered, the plateau itself clears earlier in the season and offers expansive, easy hiking. You'll stay in traditional mountain inns and guesthouses around the plateau perimeter, enjoying South Tyrolean hospitality and cuisine.

• Duration: 7 days

• Technical: 2/5 | Fitness: 2/5

• Why it works in May: Lower elevation plateau terrain, gradual hiking without steep passes, village accommodations, stunning spring meadows

What to Pack for May in the Dolomites

May requires full shoulder-season gear—think early spring mountain conditions, not summer hiking.

Essential Clothing Layers

• Warm insulating layers (fleece or lightweight down jacket—you'll need this)

• Waterproof, breathable rain jacket and rain pants (rain and snow are likely)

• Warm hat and gloves (yes, even in May—mornings are cold, high elevations are very cold)

• Base layers that wick moisture effectively

• Long hiking pants (shorts are optimistic in May)

Footwear

• Sturdy, waterproof hiking boots with good ankle support (trails can be muddy, wet, partially snow-covered)

• Gaiters helpful for keeping boots dry on wet trails

• Comfortable shoes for evenings at guesthouses

Gear

• Trekking poles (highly recommended for muddy, slippery, or uneven trails)

• Sunglasses and sunscreen (UV is strong at altitude even in May)

• Headlamp with extra batteries

• Lightweight backpack for carrying layers as temperatures fluctuate

What to Leave Behind

• Summer-weight clothing (you'll be cold)

• Expectations of hot weather hiking (this is spring, not summer)
