El Tromen Provincial Park


With its arid landscapes and the impressive Tromen volcano, surrounded by lava flows and slag heaps, this park is an ideal place to discover the surprising nature of northern Neuquén. 

The best time to visit is from November to April.

What to see
Trekking and mountaineering amid birds

The park is ideal for trekking, mountaineering and bird watching, as it protects the Tromen lagoon and the Los Barros marshland, two wetlands chosen by many water and migratory birds (it has been a Ramsar site since 2006).

A trekking path surrounds the lagoon (approximately 4 hours long) and another trail surrounds the marshland (approximately 2 hours).

Ascent to Tromen

It is the second highest peak in Patagonia. The tours usually last 3 days and are carried out with qualified guides. It is about a 5-hour walk to the high camp at approximately 3,100 m.a.s.l., and the next day, the ascent to the summit at 4,114 m.a.s.l.

Trekking and mountain bike 

In addition to the ascent to the volcano, you can trek and bike to the Yesera del Tromen lagoon from the town of Buta Ranquil, going through a landscape of gypsum, limestone, anhydrite and asphaltite. Check for authorized guides.

Transhumance culture

A great cultural attraction is the presence of rural residents who practise transhumance cattle breeding of goats, sheep, cows, horses and mules, following the ancestral trails of ancient muleteers.

How to get there and move around

The park is located north of Neuquén. The main access is from La Salada area on National Route 40, 8 km north of Chos Malal. From there, it is about 24 km of gravel road through Provincial Routes 2 and 37 to the access to the park.

Access is also available from Buta Ranquil and from the town of Barrancas, but it is convenient to check the condition of the roads beforehand.
