About This Route
The Tre Cime di Lavaredo Circuit, also known as Sentiero 105, circles the iconic three peaks in the Sexten Dolomites. This 10 km loop starts at Rifugio Auronzo, reachable by shuttle from Lago di Misurina, and offers prime birdwatching for golden eagles soaring over sheer cliffs, black redstarts nesting in rocky crevices, and alpine swifts darting through the air. Expect 4-6 hours round trip with 400m elevation gain, passing rifugios like Lavaredo and Locatelli for panoramic views and bird perches. Spring and summer bring breeding pairs of peregrine falcons; follow Leave No Trace principles by staying on trails to avoid disturbing nests protected under EU Birds Directive.
Safety Considerations
Weather shifts rapidly above 2,300m; afternoon thunderstorms are common June through August, per CAI (Club Alpino Italiano) reports. Exposed sections risk rockfall from cliff faces; watch for chamois dislodging stones. Altitude sickness hits unprepared hikers; hydrate and ascend gradually. Crowds peak mid-summer, increasing slip hazards on gravel paths. Ticks thrive in meadows, carrying Lyme disease; check gear post-hike. Wildlife encounters include protective capercaillie during mating season (April-May); maintain 50m distance as advised by Parco Naturale delle Tre Cime. No cell service in valleys; refugios have satellite phones.
Essential Gear
Pack REI Co-op binoculars (8x42 for low-light eagle spotting), a lightweight spotting scope like Vortex Razor HD, layered clothing (merino base, Gore-Tex shell), sturdy boots (Salomon X Ultra for grip), trekking poles, and a first-aid kit with blister pads, tweezers for ticks, and altitude meds like ibuprofen. Include a whistle, headlamp, and offline maps via Gaia GPS app pre-loaded with Sentiero 105 GPX.
