Fodor's Expert Review La Garganta del Diablo
Tilcara Nature Sight Free
Seven km (4 miles) west of town is La Garganta del Diablo (The Devil's Throat), a red-rock gorge with waterfalls (the number depends on the season). The tourist office in Tilcara can point you in the right direction; ask about the path that knocks about half the distance off the journey. Ask, too, for directions to the wind-eroded caves that are a similar distance east of town.
