A morning half-marathon loop through volcanic ash trails and alerce forest above Lago Todos Los Santos
The Half Marathon 21K (real distance 20.5km) offers an accessible entry into Vulcano's volcanic terrain. An easy flat opening on volcanic ash crosses three lava aluviones before the course climbs a shorter section of the Quebrada Jurásica, gaining 600m. The descent returns via Sendero Desolación, then winds through old-growth alerce forest to finish along the shore of Lago Todos Los Santos.
