This route was planned by komoot.
The ascent to Rifugio Semenza from Pian de le Lastre typically takes about 3.5 to 4 hours. The Komoot tour data estimates the one-way duration at approximately 5 hours and 46 minutes, covering just over 12 kilometers.
No, this trail is rated as 'difficult' and is best suited for experienced hikers with a good level of fitness and alpine experience. The central part of the ascent is steep, and some sections can be exposed and treacherous, occasionally featuring fixed ropes for assistance.
The route begins on a dirt road from Malga Pian delle Lastre, then transitions to a path (trail marker 926) through a magnificent beechwood forest. As you gain elevation, the path becomes steeper, leading to a ridge. The trail then traverses along the mountainside, crossing steep valleys and a gravelly basin, with an artificial ledge before reaching the rifugio. Expect diverse landscapes including forests, pastures, and rocky areas.
You'll encounter several notable features. Highlights include the expansive Foresta del Cansiglio, the charming Casera Palantina, and the unique Sasson della Madonna. As you ascend, you'll reach Forcella Lastè, and near the end, the Carlo and Massimo Semenza Mountain Hut itself. Don't miss the stunning View of Alpago and Lake Santa Croce.
The best time to undertake this hike is generally from May to November. However, July to September are ideal months, as the weather is typically more stable and the refuges, including Rifugio Semenza, are usually open during this period.
The trailhead typically starts from Malga Pian delle Lastre at 1250 meters. Parking is usually available near this area. Public transport options to Pian de le Lastre are limited, so driving is often the most convenient way to reach the starting point.
Regulations regarding dogs on trails in the Dolomites can vary. While many trails permit dogs, it's always advisable to keep them on a leash, especially in protected areas or near livestock. Given the challenging terrain and potential exposure, ensure your dog is fit for such a hike and carry enough water for them.
Generally, hiking permits are not required for accessing trails in the Dolomites, including this section of the Alta Via 7. There are typically no entrance fees for hiking within the Foresta del Cansiglio. However, it's always good practice to check local regulations before your trip, especially if you plan to stay overnight in a refuge, which requires booking.
Yes, this route shares sections with several other official trails. You'll find it intersects with parts of the Alta via n. 6 delle Dolomiti - XI tappa, Sentiero dei cippi della Serenissima, and to a lesser extent, Sulle tracce del cervo, Alta via n. 6 delle Dolomiti - X tappa, Alta via n. 7 delle Dolomiti - IV Tappa, Sentiero Alpago Natura, and Sentiero Gerometta.
Given the challenging nature and the relative scarcity of shelters compared to other Dolomite high routes, careful planning is essential. You should pack sufficient water, as sources may be limited along the trail. Essential gear includes sturdy hiking boots, appropriate layers for changing mountain weather, navigation tools, first-aid supplies, and snacks. If planning an overnight stay, ensure you have a reservation at Rifugio Semenza.
This specific section of the Alta Via 7 is typically hiked as a point-to-point route, leading from Pian de le Lastre to Rifugio Semenza. While it's possible to hike it as an out-and-back, the name suggests it's a segment of a longer traverse. The Komoot tour data indicates equal elevation gain and loss, which could imply an out-and-back if you return the same way.
First group outing with the CAI for the 2025 via ferrata course. No equipped routes, for now, but an introductory outing in which we reached the Rifugio Semenza, in a beautiful circular itinerary in the Prealps, combining walking with various moments of in-depth study on climbing techniques in a snowy environment. This course is exactly what I would have liked to do years ago: study of the mountains, the correct equipment, the techniques. What can I say, better late than never.
