In northern Argentina, El Puente del Diablo in La Poma amazes travelers with its unique natural formation and striking landscapes. This basalt rock tunnel, carved by nature, provides an uncommon experience in the Valles Calchaquíes. Surrounded by mountains and the Calchaquí River, it draws those seeking adventures like spelunking and hikes.
El Puente del Diablo is located in La Poma, a small village in Salta province, along National Route 40, between Cachi and San Antonio de los Cobres. This area, part of the Valles Calchaquíes, stands out for its natural and cultural wealth, featuring broken mountains, pre-puna landscapes, and views of Nevado de Acay. Churches, volcanoes, caves, and archaeological sites enhance the surroundings.
The main attraction is a natural basalt rock tunnel formed in the Calchaquí River bed. Descending to the river, visitors see mineral formations hanging from the ceiling and rising from the floor. Light filtering through openings creates a unique atmosphere, paired with the sound of water, perfect for photography.
Activities include spelunking to explore the tunnel's interior with licensed guides, mindful of humidity and uneven terrain. Nearby trails offer hikes, and visits to volcanic formations round out a full-day circuit.
From Salta, follow Route 40 to Cachi, then ascend to La Poma. The journey mixes gravel, steep curves, and mountains, lasting several hours. Organized tours with transport and guides are advised, or use a personal vehicle, checking weather and road conditions beforehand.
