What to see
Los Bolillos
Before reaching the natural area, 20 km away from Varvarco along Provincial Route 43 in La Matancilla, there is an attraction known as "Los Bolillos" that brings together extraordinary and capricious rock formations with reddish and yellow tones that contrast with the Varvarco river ravine. You can take a 7 km detour to get there from Provincial Route 43. Check the condition in advance, as the road has just a vehicle track mark in some sections.
Atreuco and Covunco ravines
Continuing along Provincial Route 43 to the north, you will reach two impressive canyons: Cajón del Atreuco, gateway to the protected natural area, and Cajón del Covunco, which hosts a natural viewpoint with beautiful views. These sectors can be explored inside only with an authorized guide in the months of January, February and March. The rest of the year there is a closed season for the preservation of the fauna of the place.
Ascent to Domuyo
The Domuyo summit is the highest in Patagonia, with 4,709 m.a.s.l. and is considered a preparation for the most important peaks of the Andes. Climbing the Domuyo takes 4 to 5 days and given its complexity, it requires a specific ascent plan. It is advisable to do it with a qualified guide if you do not have experience in high mountains. The ascent begins from Punta de Camino, a detour of about 14 km from the park ranger station.
Geysers
"Los Tachos", with hot springs and geysers, is another place you can go to when you take the detour. Also, “El Humazo”, which harbours underground thermal springs with high temperatures on the ground and on the rock walls. To get to the latter, check accessibility with the park rangers.
Hot waters and thermal baths
Villa Aguas Calientes is a small valley crossed by a stream with thermal water pools and cabins. Continuing along Provincial Route 43 to the north, you will find “Las Olletas” and “Rincón de las Papas”, which harbour small geysers. Check accessibility at the moment with park rangers or the Varvarco information office.
Warning
Geysers and steam-water outcrops rise at temperatures above 90°C. It is important to respect the distances and the places where you can move around. The area has few services.
