Leverogne - La Ravoire - Baise Pierre - Baulin (Avise)

One of Valgrisenche's most demanding valley-floor-to-alp routes, this 6.2 km trail climbs over 1000 metres from Leverogne (767 m) to Baulin (1763 m). Passing through the partly abandoned hamlet of La Ravoire — with its stone ruins still standing among encroaching vegetation — the path ascends through chestnut and oak woodland before opening into larch forest and high pasture. Rated E; solid fitness required. The long descent back to the valley floor should be factored into planning.
