From the lake onwards, the fun is over for mountain bikers; from there it's a steep uphill climb over huge boulders, requiring carrying, climbing, and lifting the bike. It's only for hardcore bikers, but it's a great area and a beautiful refuge.

The Vallanta refuge is located at 2,450 meters above sea level, under the west face of Monviso. It is an excellent stopover for those who travel the Giro del Monviso, but also for those who love mountaineering and reaching the peaks above. The refuge is open from mid-June to mid-September, during the closing period a spacious winter bivouac is available. In summer, reservations are required to stay overnight.

The lakes around Ostana are primarily glacial alpine lakes set against the dramatic backdrop of the Monviso mountain, often called the 'King of Stone.' They are known for their stunning reflections of the peaks, clear waters, and unique natural features like the striking turquoise color of Lake Chiaretto.
Lake Chiaretto is particularly famous for its striking turquoise color, attributed to the smaragdite mineral in the Monviso ophiolites. Lake Lestio is also a small, beautiful turquoise blue glacial lake.
Many of the lakes, including Lake Fiorenza, are easily reachable from Pian del Re, which serves as a common starting point for hikes. While some paths can be intense, the initial sections to these popular lakes are generally manageable for those with basic hiking experience, making them suitable for families.
The lakes are integral to various hiking trails, including the popular 'Giro dei Laghi' (Lake Tour) and the longer 'Giro del Monviso.' You can find diverse routes, from moderate walks to challenging alpine treks. For more hiking options, explore the Hiking around Ostana guide.
Pian del Re is the most common starting point for accessing many of the alpine lakes, including Lake Fiorenza and Lake Chiaretto. It's also the location of the Pian del Re Hut, which offers services.
Yes, there are mountain huts (rifugi) near some of the lakes that offer accommodation. For example, the Vallanta Hut is located near Lago Grande di Viso and is an excellent stopover for those on the Giro del Monviso. The Pian del Re Hut also offers beds and services.
The best time to visit is generally from early June to late September when the snow has melted, and the trails are clear. During this period, mountain huts are typically open, and the weather is most favorable for hiking. Winter offers opportunities for snowshoeing, but access to some lakes may be limited.
While specific permits for general hiking are not typically required for day trips to the lakes, it's always advisable to check local regulations, especially if you plan to undertake more challenging routes or stay overnight in protected areas. The Monviso area is part of a natural park, so respecting environmental rules is crucial.
Generally, dogs are allowed on trails in the Monviso area, but they should be kept on a leash, especially in protected areas or where wildlife is present. Always ensure you clean up after your pet and respect other hikers and the natural environment.
The alpine environment around the lakes is home to various wildlife. Near Lake Fiorenza, it's possible to spot the rare black salamander. Other common sightings include marmots, chamois, ibex, and various bird species.
While direct facilities at every lake are limited, mountain huts like the Pian del Re Hut and the Vallanta Hut offer bar and restaurant services, as well as accommodation. These are typically located along popular hiking routes to the lakes.
The 'Giro del Monviso' is a multi-day, challenging alpine route that passes by several lakes, including Lago Grande di Viso. Some sections of the trails, especially those leading to higher elevation lakes like Lago Superiore di Viso, can be steep and require good physical condition and appropriate gear.
Public transport options to Ostana itself might be limited. From Ostana, access to the lakes is primarily via hiking trails, often starting from Pian del Re. It's recommended to check local bus schedules to Crissolo or other nearby towns, and then plan for a taxi or a longer hike to reach trailheads like Pian del Re.
