Surrounded by forested mountains, this idyllic lake fills a volcanic crater that's over 100m deep and 2km in diameter. You can walk around the lake and in the surrounding mountains, climb to an abandoned gold mine, cycle, swim, kayak, fish and bird-watch (some 250 species) here. By bus, catch a ‘Santa MarÃa del Oro’ colectivo (M$35, 45 minutes) on Avenida México in Tepic, then change to a colectivo marked ‘Laguna’ at Santa MarÃa’s town square or take a taxi.
Incredibly photogenic, the clean water takes on colors ranging from turquoise to slate. A number of restaurants serve fresh lake fish.
If driving, take the Santa MarÃa del Oro turnoff about 40km from Tepic along the Guadalajara road. From the turnoff it’s about 9km to Santa MarÃa del Oro village, then another 8km to the lake.
