How to get to the Casiri lagoons by car?

The drive begins in the remote village of Caquena. From the village, the road stretches for 16.1 km, climbing steadily toward the high plateau. The route involves an elevation gain of 540 meters, ending at the shores of the lakes: Casiri Hembra (4,825m) and Casiri Macho (4,856m).

What are the road conditions in this volcanic area?

The surface is entirely unpaved, consisting of gravel and loose volcanic rocks. The track is described as "tippy" and bumpy, with several steep sections that require technical driving. Due to the loose surface and the high gradients, a 4x4 vehicle is strictly required. This is a trail designed for experienced off-roaders; avoid this route if unpaved mountain tracks are not your strong point.

Weather and altitude hazards

At nearly 4,900 meters above sea level, the effects of altitude (hypoxia) are noticeable for both drivers and engines. The road is usually impassable during the winter months due to snow. Additionally, sudden summer thunderstorms can rapidly transform the dry gravel into a muddy trap, making the road dangerous or completely impassable in minutes.

A landscape of volcanoes and algae gardens

The journey is well worth the effort for the stunning surrounding landscape of volcanoes and sharp rocky peaks. Laguna Casiri Macho is particularly unique for its underwater algae garden visible in the southern area. Despite the harsh conditions, mosquitoes are abundant along the edges of the lagoons, which are framed by ancient volcanic rock formations.

Driving safety and preparation

Given the extreme isolation near the Bolivian border, travelers must be fully self-sufficient. Ensure your vehicle is in top mechanical condition and carry extra supplies. The road is narrow and winding, with sharp curves that demand constant focus, especially when navigating the rocky embankments at such extreme elevations.
