Lake della Rossa

Highlight • Lake

The Lago della Rossa is located in the municipality of Usseglio and is the largest lake in the Lanzo Valleys. It is a very beautiful lake, one of the most spectacular destinations in the valley.

The Red Lake takes its name from the top of the Red Cross, 3566 meters high, which is reflected in its waters.

It was born as a small natural lake, then the construction of the dam, which took place between 1931 and 1934, made it significantly expand and made it, at the time, the highest artificial lake in Europe.

This is a demanding route, categorized as a "difficult" hike requiring very good fitness, sure-footedness, and sturdy shoes. It involves sustained ascents and potentially rugged sections typical of alpine environments. Hikers should have prior alpine experience.

What are the main points of interest along the route?

The trail offers stunning high-mountain scenery. You'll encounter the beautiful, often turquoise waters of Lake della Rossa, which is the largest lake in the Lanzo Valleys. The route also passes by the Bartolomeo Gastaldi Refuge and crosses the Collarin d'Arnas, providing panoramic views of granite peaks and the Croce Rossa peak reflected in the lake's waters.

Where can I park for the Lago della Rossa Loop Trail?

The trail typically starts from the Vallone d'Arnas area. While specific parking details aren't provided, access points for trails in the Valli di Lanzo often have designated parking areas near trailheads. It's advisable to check local regulations or specific starting points for the most convenient parking options.

Is public transport available to reach the trailhead?

Access to remote alpine trailheads like this one in the Valli di Lanzo can be challenging via public transport. While some bus services might reach nearby villages, reaching the exact trailhead often requires a private vehicle or a local taxi service. Always check regional transport schedules in advance.

What is the best time of year to hike this loop?

Given its high-alpine nature and significant elevation, the best time to hike this trail is typically during the summer months, from late June to early September, when snow has melted and weather conditions are generally more stable. Always check current weather forecasts and trail conditions before you go.

Are dogs allowed on the Lago della Rossa Loop Trail?

Generally, dogs are permitted on trails in the Valli di Lanzo, but they must be kept on a leash, especially in areas with livestock or protected wildlife. Always ensure your dog is well-behaved and capable of handling a long, difficult hike in alpine terrain.

Do I need a permit or is there an entrance fee for the Valli di Lanzo area?

There are typically no specific permits or entrance fees required for hiking the Lago della Rossa Loop Trail itself within the Valli di Lanzo. However, always respect local regulations, especially concerning protected areas or private land. If you plan to stay overnight in a refuge, reservations are usually required.

Are there any facilities or refuges along the way?

Yes, the route passes by the Bartolomeo Gastaldi Refuge, which can provide a place for rest, food, and potentially overnight stays. It's always a good idea to check the refuge's opening hours and make reservations if you plan to rely on their services.

What should I pack for this difficult hike?

For a difficult alpine hike like this, you should pack sturdy hiking boots, appropriate layers of clothing for varying weather conditions, rain gear, plenty of water, high-energy snacks, a map and compass (or GPS device), a first-aid kit, and sun protection. Trekking poles are also highly recommended for stability on ascents and descents.

Is the Lago della Rossa Loop Trail suitable for families or beginners?

No, this trail is not recommended for beginners or young children. Its "difficult" rating, significant elevation gain, and long distance require very good fitness and alpine experience. Families with younger children or those new to hiking should look for easier routes in the Valli di Lanzo.

What makes Lake della Rossa unique?

Lake della Rossa is notable for being the largest lake in the Lanzo Valleys. It's also an artificial lake, constructed between 1931 and 1934, and was once considered the highest artificial lake in Europe. Its beautiful turquoise waters, reflecting the surrounding granite peaks like Croce Rossa, make it a truly striking feature of the landscape.
