Piz Blaisun, Mountain summit in Grisons, Switzerland
Piz Blaisun is a mountain peak in Grisons standing at 3,200 meters where three valleys meet: Val Tuors, Val d'Alvra, and Val d'Es-cha. The summit displays typical Alpine morphology with steep slopes and ridges that define the terrain between these valleys.
The mountain has served for centuries as a marking point for travelers crossing the Albula Pass and nearby mountain routes through the Alps. Its position along this important transit route made it a well-known landmark in Alpine navigation.
The name Piz Blaisun comes from Romansh, the local Alpine language still spoken in this region and tied to the identity of its communities. This mountain serves as a geographical reference point that locals use when describing their connection to the surrounding valleys and their shared landscape.
Hikers reach the summit by following a trail from Albula Pass toward Fuorcla Gualdauna, with the easiest conditions occurring during summer months. The terrain demands good fitness and mountain experience, especially on the exposed sections.
The location where three valleys meet creates special wind patterns that affect local weather throughout the year. These meteorological conditions make the mountain a subject of local weather observation and climbers report unexpected wind shifts during ascent.
