Embark on a challenging hike along the Fellaria Glacier and Marson Glaciological Trail, a difficult route spanning 8.8 miles (14.1 km). You'll gain 2281 feet (695 metres) in elevation, requiring about 5 hours and 39 minutes to complete. This trail immerses you in dramatic alpine scenery, starting with the impressive Campo Moro and Gera dams. As you progress, the path winds through a unique "lunar landscape" of glacial moraines. The highlight is the spectacular view of the Fellaria Glacier, where you might witness a glacial lagoon dotted with floating icebergs and cascading waterfalls, all framed by the majestic peaks of Mount Bernina. This demanding terrain requires good fitness and sure-footedness.
To best experience the Fellaria Glacier and Marson Glaciological Trail, plan your hike between May and October. This timeframe helps you avoid snowmelt and high water levels, ensuring safer passage. Given its difficult rating, this route is not suitable for beginners; you should have prior alpine experience and be prepared for varied, demanding terrain. Always wear sturdy hiking shoes and carry appropriate gear for changing mountain weather conditions. Start your hike early in the day to allow ample time for completion before dusk.
This glaciological trail offers a unique opportunity to witness the dynamic forces of nature at play. The route guides you through an environment shaped by ancient glaciers, revealing geological formations like moraines that tell the story of the region's icy past. Observing the Fellaria Glacier and its associated features provides a direct connection to the ongoing processes of glacial retreat and landscape evolution. It's a profound experience for anyone interested in alpine geology and the raw beauty of high-mountain environments.

Frequently Asked Questions
What is the best time of year to hike to the Fellaria Glacier and Campo Moro dams?
The ideal time to undertake this hike is from May to October. It's best to avoid winter and early spring due to potential snowmelt, higher water levels, and more challenging conditions.
What is the terrain like on this trail?
The trail offers a varied and often demanding terrain. You'll encounter sections of packed dirt, rocky paths, and coarse-grained scree. There are parts with loose rock and uneven surfaces due to glacial moraines, and some exposed sections require caution. While the initial ascent to the Roberto Bignami Hut is more gradual, the path becomes steeper and more rugged as you approach the glacier.
Is the trail to the Fellaria Glacier and Campo Moro dams suitable for beginners?
No, this trail is generally considered difficult and is not recommended for beginners. It demands good to very good fitness, sure-footedness, sturdy hiking shoes, and some alpine experience. The overall hike to the glacier is challenging, with sections that can be technical or hazardous.
What can I see along the route?
This route offers breathtaking scenery. You'll pass the impressive Campo Moro and Gera dams, leading to expansive reservoirs. As you ascend, the landscape transforms into a 'lunar landscape' of glacial moraines. The highlight is the spectacular Fellaria Glacier, featuring a glacial lagoon with floating icebergs and even ice caves. You'll also see Fellaria Glacier Waterfalls and have panoramic views of the surrounding mountains, including the majestic Mount Bernina. Keep an eye out for ibex!
Where can I park for the Fellaria Glacier and Campo Moro dams hike?
The trail typically starts from the Campo Moro area. Parking is available near the dams. It's advisable to arrive early, especially during peak season, as parking can fill up quickly.
Are dogs allowed on the trail?
Generally, dogs are allowed on trails in the Valmalenco region, but they should always be kept on a leash, especially in alpine environments where wildlife is present and to ensure the safety of other hikers and livestock. Always clean up after your pet.
Do I need a permit or pay an entrance fee for this hike in Valmalenco?
There are no specific permits or entrance fees required to hike this particular trail to the Fellaria Glacier and Campo Moro dams. However, always respect local regulations and alpine etiquette when exploring the Valmalenco region.
Does this route intersect with other well-known paths?
Yes, the route intersects with several other trails. You'll find sections that are part of the Sentiero Italia - Tappa D26N, the Alta Via della Valmalenco - Tappa 7, and the Sentiero glaciologico Luigi Marson C, among others.
Are there any facilities or amenities near the Campo Moro trailhead?
The Roberto Bignami Hut is a notable stop along the way, offering a place to rest and enjoy spectacular views. It's always a good idea to check their operating hours if you plan to rely on their services. Basic amenities might be available in the Campo Moro area, but it's best to be self-sufficient for food and water.
What should I bring for this hike?
Given the trail's difficulty and alpine environment, you should bring sturdy hiking boots with good ankle support, appropriate layers of clothing for varying weather conditions (even in summer), rain gear, plenty of water, high-energy snacks, a map and compass or GPS device, sunscreen, sunglasses, and a first-aid kit. Trekking poles are highly recommended for stability on rocky and uneven terrain.
Is there a specific 'hidden gem' or strategy for hiking this trail?
While not a 'hidden gem' in the traditional sense, a strategic approach is to consider the 'Marson' Glaciological Path. It offers various routes (A, B, and C) that provide deeper insights into the glacier's dynamics and the area's geomorphology. For a true alpine experience, aiming to reach the glacial lagoon with its ice caves and icebergs is a unique reward, especially in late summer when these features are most prominent due to glacial melt.

Trail Reviews
In the video you find here I tell my trek step by step. These 13 km that start from the Campo Moro dam taking the left side of the lake (not the right) to arrive at the Bignami refuge after 3 km. After the Refuge, there is immediately Alpe Fellaria and from there begins the Luigi Marson Glaciological Path which takes you to the glacier in just over an hour (where you take route C and not route A or B). a small wooden bridge before the waterfall is the final km which is a bit physically difficult but then a magnificent scenario opens up. On the way back, take the same route up to the Bignami refuge and then descend on the opposite side of the lake where you will see the waterfall and then arrive at Alpe Gembrè and then return to the dam. This side of the lake should be done in the afternoon when the colors are much more beautiful with the sun. This is the video: Subscribe to the channel if you like it and activate the bell so you don't miss the next ones :) https://youtu.be/1G2Tmnn6LZ4
We parked in the parking lot below the Alpe Gera dam (€6 all day), climbed up to the dam, and headed for the trail that leads to the Poschiavina Valley. We then continued along the trail toward Alpe Gembrè, and from there we reached the waterfalls of Lake Taleccio. Shortly after the small bridge on the right, we took the ridge trail overlooking the lake, which led to the junction with the trail from the Bignami refuge. We turned right and continued toward the Fellaria glacier, on a trail that passes where the glacier once stood, and now, as it retreats, you can see how it has shaped the rocks. Once we reached the Fellaria glacier, we stopped for lunch just above the shore of the lake; it's a natural spectacle, being there so close to the glacier is beautiful. We returned and reached the Bignami refuge, then descended to the dam and returned to the cars. The trail is suitable for everyone. There are no exposed sections, but good fitness is recommended. It's also suitable for dogs. I always recommend bringing them if they're trained and accustomed to the mountains.
Girolago with a (mandatory) stop at the Fellaria glacier, lunch stop at the Bignami refuge. Departure from the right side of the lake in the shade in the morning. The route itself is not particularly demanding, certainly the distance makes itself felt at the end. The most complicated part is the stony path to reach the glacial lake.
Departure from Campo Moro leaving the car at the paid parking of the Poschiavino Refuge (possibility to pay with cards) or shortly after along the road (free) or at the paid parking under the Alpe Gera lake (dam). Climb up to the dam and reach the Bignami refuge either from the direct road or, as in our case, by going around the lake counterclockwise. From Bignami it is possible to follow one or more glaciological paths, all well marked. We decided to reach Lake Fasso (the path requires particular attention and could create problems for non-experts or those suffering from vertigo) and then, from there, the Fellaria glacier. Although it has shrunk in recent years, it is well worth the visit. To reach it, the path is mainly on stones and boulders. From the glacier we returned to Bignami (excellent lunch with generous portions) and to return we completed the tour of the lake.
