Hiking activities in Quebrada De Humahuaca
Based in the Posada de Luz, Caravana de Llamas is a recommended llama-trekking operator running half-day excursions (AR$140) around Tilcara, day trips in the Salinas Grandes (AR$180) and multiday excursions, including a five-day marathon from Las Yungas lowlands to Tilcara (AR$1750 to AR$2600). The guide is personable and well informed about the area. Llamas are pack animals: you walk, they carry the bags.
Of several interesting walks around Tilcara, the most popular is the two-hour hike to Garganta del Diablo, a pretty canyon and waterfall. Head toward the pucará, but turn left along the river before crossing the bridge. The path to the Garganta leaves this road to the left just after a sign that says 'Cuide la flora y fauna'. Swimming is best in the morning, when the sun is on the pool.
