The hike from Passo Giau to Lago delle Baste typically takes about 1 hour and 15 minutes to 1 hour and 30 minutes one way. This estimate is for the segment itself, not a broader day hike in the area.
The initial stages of the trail from Passo Giau to Forcella di Zonia and Forcella di Col Piombin are largely a level, dirt footpath. It then crosses the slopes of Col Piombin. As you descend towards Lago delle Baste, the path is unmarked but well-trodden, passing through a cluster of fallen boulders. The area around the lake features marshy grasslands. While this segment is generally accessible, sturdy shoes and sure-footedness are recommended due to the Dolomites' rocky and steep terrain.
From Passo Giau, you can enjoy panoramic views of the Tofane Group, Monte Pore, Marmolada, and the Sella Group. The pass itself is known for its dramatic rock formations and wildflowers. As you hike, you'll traverse the Mondeval plateau, offering views of Spiz de Mondeval, Cima Ambrizzola, Ponta Lastoi de Formin, and the formidable Monte Pelmo. Lago delle Baste provides a picturesque foreground for Monte Pelmo and Lastoni di Formin.
This specific segment of the Alta Via 1, from Passo Giau to Lago delle Baste, is generally considered easy to moderate. It's often described as a pleasant walk and is one of the easier sections of the Alta Via 1. However, the overall difficulty of the Alta Via 1 is rated as 'difficult', so while this part is more accessible, hikers should still be prepared for mountain terrain and wear appropriate footwear.
Passo Giau is a well-known mountain pass with ample parking available, making it an accessible starting point for this hike. It's advisable to arrive early during peak season to secure a spot.
Public transport options to Passo Giau are available, typically by bus from nearby towns like Cortina d'Ampezzo. Services can be seasonal and less frequent outside of peak summer months. We recommend checking local bus schedules and routes for the Dolomites region before your trip for the most up-to-date information.
The best time to hike this trail is generally from late spring to early autumn (June to September). During these months, the weather is more stable, the snow has melted, and the meadows are green with wildflowers. Always check the local weather forecast before heading out, as conditions in the Dolomites can change rapidly.
Yes, the trail is generally dog-friendly. However, dogs should be kept on a leash to protect local wildlife and respect other hikers. Always remember to pack out any waste and ensure your dog is accustomed to mountain terrain.
No, you do not need a specific permit or to pay an entrance fee to hike this section of the Alta Via 1. The trail is freely accessible to the public. However, please respect the natural environment and follow any local regulations.
Yes, this route is part of the famous Alta Via n. 1 delle Dolomiti - Dolomiten-Höhenweg Nr. 1. It also overlaps with sections of the Via Alpina Yellow B20. You may also encounter parts of the Via Normale Monte Cernera and Alle pareti di Lastoi Formin trails.
While there are no direct refuges or amenities right at Lago delle Baste, you'll find facilities, including restaurants and accommodation, at Passo Giau, which is the starting point of this hike. It's always a good idea to carry enough water and snacks for your journey.
Given the mountain environment, even for an 'easy to moderate' section, it's essential to wear sturdy hiking boots with good ankle support. Dress in layers, as weather can change quickly. Bring rain gear, sun protection (hat, sunglasses, sunscreen), sufficient water, snacks, a map or GPS device, and a first-aid kit. Trekking poles can also be helpful for stability on uneven terrain.
At this time of year you are alone - next time I would prefer the evening light for taking photos.
Especially in autumn, a fantastic color image forms at sunset. Then the yellow grass shines along with the glow of the mountains. Definitely take flashlights with you for the way back, because the descent is slippery in a few places.
First part of a two-day trek, with a stop on Lago delle Baste, temporary camping in a tent to admire the sunrise and then continue to Croda da Lago.
