Croda da Lago is one of the most distinctive mountain groups surrounding Cortina d’Ampezzo, with a line of jagged peaks rising above the forests and the beautiful Lago Federa.

The full circular trail takes you around the mountain group, crossing high passes and open rocky terrain before reaching Lago Federa and Rifugio Croda da Lago. It looked like one of the best all-round hiking days near Cortina, combining quiet woodland, dramatic viewpoints, a proper mountain circuit and one of the most photogenic lakes in the Dolomites.

That was the route we had planned, but the mountain had other ideas.

We visited at the end of May, when Cortina was enjoying warm sunshine but a considerable amount of snow still covered the higher parts of the trail. We followed the circuit clockwise from Cason de Formin and made it far enough to reach the open ground beneath the peaks, but the snow eventually became too deep and uncertain for us to continue safely.

Rather than force the route, we returned to the junction and followed the alternative path towards Lago Federa. It meant we couldn’t complete the full Croda da Lago circuit, but the day still gave us magnificent mountain views, enchanting forests and a frozen Lago Federa that looked almost too perfect to be real.

It wasn’t the route we had planned, but it became another reminder that hiking in the Dolomites, particularly early in the season, is often about adapting to the conditions and enjoying the experience you are given.

Croda da Lago is one of several memorable hikes close to Cortina d’Ampezzo.

Hike Description

The hike begins at Ponte de Ru Curto, beside the SP638 road between Cortina d’Ampezzo and Passo Giau.

The trailhead sits beside a long roadside parking area and is marked by a large information board. From here, we followed Trail 437 towards Cason de Formin and Rifugio Croda da Lago.

The route initially drops away from the road and crosses two small streams before entering the forest. It is a beautiful beginning, with tall trees surrounding the trail and the sound of running water drifting through the woodland.

The path soon begins to climb, but the gradient initially feels steady rather than severe. We followed well-worn forest tracks, crossed several small bridges and walked over wooden sections built across uneven ground and larger rocks.

Everything felt green, quiet and almost hidden from the mountains above.

As we continued, the trail passed beside a deep gorge carved through the rock. A bridge carries the path across it, and even during our visit it was an impressive feature. Earlier in spring, when snowmelt feeds the streams, I imagine the water rushing through it must be incredibly loud.

Beyond the gorge, the climb continued through the trees until we reached a more open clearing at Cason de Formin. A small wooden building stands near the junction, and we stopped there for a break before deciding which way to continue.

This is an important point on the route.

The left-hand trail provides the more direct approach towards Lago Federa and Rifugio Croda da Lago, while the paths heading right lead towards the higher ground used by the full circuit around Croda da Lago.

Our plan was to complete the circuit, so we initially turned right.

The path climbed through the forest before gradually emerging onto more open terrain. The jagged peaks of Croda da Lago began to appear on our left, and for a while it felt as though the full route might still be possible.

However, as we gained height, the snow became deeper.

We tried to continue, following the line left by previous walkers, but the ground ahead became increasingly difficult to judge. The snow covered the path and concealed the uneven rocky terrain beneath it, while the route was beginning to move into more serious mountain surroundings.

We had reached a position almost level with the peaks and had finally gained the views we had hoped for, but continuing simply did not feel sensible.

Turning around was disappointing, especially after coming so close to the higher section of the circuit, but it was an easy decision once we looked properly at the conditions.

We retraced our steps to Cason de Formin and took the alternative path towards Lago Federa.

The trail climbed steeply through the forest before reaching a viewpoint that stopped all of us in our tracks. The trees opened completely, revealing an enormous panorama across the Dolomites.

From there, we could pick out Cinque Torri, Nuvolau, Tofana di Rozes, the Pomagagnon range and the Sorapis group. We spent a long time standing at the edge of the viewpoint, taking in the scale of the landscape and realising just how much height we had gained since leaving the road.

It was one of the best views of our entire Dolomites trip.

After eventually dragging ourselves away, we returned to the path and continued towards Lago Federa.

The route passed through another wonderful section of forest. There was still deep snow in places, but enough walkers had passed through to create a visible line, and it felt much more manageable than the higher route we had abandoned.

The climb remained steep for a while, but the surroundings made it easy to forget about the effort. Snow-covered trees, shafts of sunlight and occasional glimpses of the peaks gave the woodland an almost storybook atmosphere.

Eventually, the gradient eased, and we passed through a gate and followed the gentler path through Val Negra towards the lake. After the earlier climbing, it was a relief to walk on flatter ground and know that Lago Federa was now close.

The lake appeared beneath the eastern side of Croda da Lago, almost completely frozen and surrounded by snow.

Like Lago di Sorapis, it was not the summer scene we had seen in photographs. There was no clear blue-green water or reflection of the peaks on the surface. Instead, the entire basin was white, silent and remarkably still.

We followed the edge of the lake towards Rifugio Croda da Lago, also known as Rifugio Palmieri, and sat outside the large mountain hut to eat our lunch.

From there, we could look back across the frozen lake and up towards the peaks, trying to work out where the full circuit would have brought us down if the snow had allowed us to continue.

There was naturally some disappointment that we had not completed the planned loop, but sitting beside the frozen lake made it difficult to feel that the day had been wasted. We had still walked through beautiful forests, reached one of the finest viewpoints near Cortina and experienced Lago Federa in conditions that relatively few summer visitors will ever see.

When we were ready to leave, we returned along the same route.

The descent was much quicker, taking us back through Val Negra, past the panoramic viewpoint and down through the forest to Cason de Formin. From there, we retraced Trail 437 past the gorge, over the small bridges and through the final woodland section to Ponte de Ru Curto.

I would love to return in the summer, complete the full circuit and see Lago Federa with clear water and the mountains reflected across its surface. But even without completing the loop, this was still a brilliant mountain day, and the frozen lake, silent forest and enormous views made it one I will remember for a very long time.

Practicalities

Practicalities

• Start early: This is one of the most popular hikes near Cortina d’Ampezzo. During summer the Ponte de Ru Curto parking area fills quickly, so arriving early gives you the best chance of securing a space and enjoying quieter trails.
• Parking: Free roadside parking is available at Ponte de Ru Curto on the SP638 between Cortina d’Ampezzo and Passo Giau. Parking is limited during the busiest months.
• Public transport: Seasonal buses operate between Cortina d’Ampezzo and Passo Giau, stopping close to the trailhead. Always check the latest timetable before travelling.
• Snow conditions: Snow can remain well into late spring and early summer. During our visit at the end of May the higher section of the circuit became impassable, forcing us to return and visit Lago Federa as an out-and-back walk instead.
• Navigation: The trails are well marked using the standard CAI route numbers, but carrying an offline GPX file is still recommended if cloud or snow reduces visibility.
• Difficulty: The complete circuit is a moderate to challenging mountain walk. The climb is steady rather than relentless, but several sections become rocky and more exposed above the tree line.
• Footwear: Hiking boots or shoes with good grip are recommended. Snow, mud and loose rock can all be encountered depending on the season.
• Weather: Mountain weather changes quickly in the Dolomites. Carry waterproofs and warm clothing even if the forecast looks favourable.
• Food and drink: Rifugio Croda da Lago (Rifugio Palmieri) beside Lago Federa usually serves meals, drinks and refreshments during the summer season. Opening dates vary.
• Facilities: Toilet facilities are normally available at Rifugio Croda da Lago when open, but there are no facilities along the rest of the trail.
• Wildlife: Keep an eye out for marmots, alpine birds and wildflowers during the summer months. Early mornings often provide the best chance of spotting wildlife.
• Best time to visit: Late June through September normally offers the best conditions for completing the full Croda da Lago circuit. Earlier in the season snow may still block the higher passes.
