Llanganates National Park, National park in Cotopaxi, Napo, Pastaza, and Tungurahua provinces, Ecuador

Llanganates National Park is a nature reserve in Cotopaxi, Napo, Pastaza, and Tungurahua provinces, Ecuador, covering more than two hundred thousand hectares. The terrain ranges from lowland forests just above one thousand meters to high Andean páramo above four thousand five hundred meters in elevation.

The protected area was created in 1996 and received its legal status through official decree. Inca-era legends link the region to General Rumiñahui, who is said to have hidden a treasure in the mountains.

The park's name comes from a Quechua word meaning 'beautiful mountain', and its highest peak, Cerro Hermoso, carries the same name. The park is known for the Treasure of the Llanganatis, a legendary Inca hoard that still draws treasure seekers. Visitors usually enter through Salcedo, Patate, Píllaro, Baños or Rio Verde.

Access is available through several entry points near Salcedo, Patate, Pillaro, Baños, and Rio Verde, with many trails requiring several hours of walking. Because of the considerable elevation changes, plan to adjust gradually to the thin air and bring clothing for shifting weather.

In 2013, explorers from Ecuador, France, the United Kingdom and the United States unearthed a structure 260 feet tall and 260 feet wide, built of hundreds of two-ton stone blocks, in cloud forest at 8,500 feet above sea level. The site lies 20 miles from Baños, about an eight-hour trek through swampy, mountainous jungle, and similar constructions may cover roughly a square mile.
