Lake Poschiavo

Lake Poschiavo is located at 962m above sea level in the Valposchiavo, the Italian-speaking valley of the Canton of Graubünden, in southeastern Switzerland. The name can be misleading: Poschiavo, the main village and capital of the valley, is not on the shore but a few kilometers to the north. The body of water instead stretches between Le Prese, a village overlooking its northern end, and Miralago, a small hamlet nestled at its southern end.

The presence of villages and infrastructures along the basin distinguishes this lake from an isolated destination at the end of a mountain road; on one bank passes the Bernina Railway, a line operated by the Rhaetian Railway, the railway company of Graubünden. The train allows you to reach the shore, walk around the lake, or follow just a section of it and leave from the opposite stop.

A lake between Le Prese and Miralago

The natural basin is approximately 2,5 km long and 1 km wide; at its deepest point it reaches 80 m. Its geography is also defined by the Poschiavino, the river that flows through the Poschiavo Valley, enters the lake from the north and exits to the south, continuing toward the Italian border. The water is therefore part of the inhabited valley floor, not a scene separate from local life.

At the northern end, The Prese It offers the most immediate reference point to begin the tour and preserves the memory of the sulfur springs that favored the development of spa tourism. On the opposite bank, Miralago It is a much more compact nucleus, but its location becomes important for those who walk: next to the village is in fact the second useful train stop.

Since the village of Poschiavo is located further north, a visit there should be separate from the time spent on the banks: Le Prese and Miralago are the two access points to the path along the water, while the main town, reached separately on the same railway, adds the historic center to the day.

Getting there with the Bernina Railway

Those arriving from the north see the line descending from St Moritz, a town in theEngadine, the Alpine valley beyond the Bernina Pass, the pass between Engadine and Valposchiavo. To the south, the tracks continue to Tirano, an Italian town in Valtellina, the Lombardy valley across the border; the line forms a UNESCO World Heritage site, along with the Albula Railway, the historic link between Thusis, a town in Graubünden, and St. Moritz.

To reach the lake you have to look at the timetables The Prese, to the north, or Miralago, to the south: you don't need to travel all the way to Poschiavo station. The railway line is more important for planning than the Bernina Express, the panoramic service that doesn't automatically identify all trains in circulation; stops, connections, and travel conditions should therefore be checked on the Rhaetian Railway's current channels.

Le Prese or Miralago?

If your goal is to complete the loop, Le Prese coincides with the departure point indicated on the official itinerary. Those who prefer a shorter walk can get off at one of the two stops, walk along one bank to Miralago or Le Prese, and start again from the opposite end. In this case, the train becomes part of the excursion and requires prior confirmation of the return time.

The Le Prese station offers step-free access to the platform, while Miralago is not designated as a barrier-free stop by the Rhaetian Railway. This information only concerns the stations and does not allow for the same assessment to be extended to the path around the lake. PostBus, the Swiss public transport network, also includes these two towns in the Valposchiavo network.

After considering public transport options, those who prefer to drive can use Le Prese as a reference point for road access. A parking area is signposted in the area, but availability should be checked on-site. If you park your vehicle here, a straightforward walk to Miralago will still take you back to the starting point.

Tour of the lake

Il Tour of the lake This is the official route that starts from Le Prese, reaches Miralago and returns along the opposite bank. It is classified as easy and measures 7,3 km, with an indicative time of 1 50 hours and minutes, 26m of ascent and the same amount of descent. The lowest point coincides with the lake's altitude, 962m above sea level, while the highest reaches 988m above sea level.

Between the railway-lined shore and the more secluded, wooded side, the relationship with the landscape changes as the loop continues. The contrast between the banks, along with the passage through two villages, allows you to appreciate the elongated shape of the lake better than simply stopping at the same spot.

The official indication includes the tour among the itineraries suitable for children, but it does not state that it is stroller-friendly or universally accessible. Those organizing hikes with specific needs should carefully consider the hiking difficulty and the characteristics of the terrain, and check the weather and trail conditions before departure.

Stopping on the banks and watching the trains pass by can extend your walk beyond the estimated time indicated on the map. When your return journey depends on a connecting train, it's best to leave some time and check the timetable before setting off.

One bank on foot, return by train

Between the two stops, you can choose a straight walk, from Le Prese to Miralago or in the opposite direction, and return by train without retracing your steps along the same shore. This option fits well into a day on the Bernina Railway and shortens the walk if you don't want to complete the entire loop.

Along the tracks, the relationship between water and railway remains prominent, while the opposite bank offers a more intimate transition between the lake and the mountainside. Traveling only one side shortens the visit and forgoes the contrast of the full loop; however, there's no need to immediately retrace your steps, provided the return train has been checked.

When time is even shorter, you can get off at Le Prese and reach the shore without confusing this stop with a visit to the village of Poschiavo. The main town is a separate location, further north: to stay on the lake, choose Le Prese or Miralago.

Lake and village of Poschiavo

On the same day, the historic center of Poschiavo can be combined with a walk along the shore without being confused with a visit to the lake: the village is the main town of the valley, while Le Prese and Miralago offer direct access to the water. All three are served by the Bernina Railway, so the train allows you to combine them without turning each trip into a return trip to the parking lot.

Those traveling through the region between Engadine and Tirano can choose a train stop and just one shore, while a full day in Valposchiavo leaves room for a complete tour and the village. With more days available, you can dedicate a day to the lake, unconstrained by travel time.

Where to stay in Valposchiavo

Those who wish to reach the water on foot in the morning will find it in The Prese the most direct base: the tour begins from the village without a preliminary transfer and the train stop remains convenient for other trips in the valley.

Choosing I poschiavo Instead, it means focusing on the village and a location distinct from the shore; to reach the lake, you take the train and get off at Le Prese or Miralago. It's a suitable base for a stay that alternates walking with other days in Valposchiavo, rather than focusing on a single hike.

From another location in the valley, Lake Poschiavo becomes a stop on a more itinerant holiday. This choice depends primarily on proximity to transport links and the time you can dedicate to its shores: Le Prese offers the most immediate access, Poschiavo allows you to stay in the capital and use the train, while a different location may be preferable if the rest of your holiday is spent elsewhere in the Poschiavo Valley.
