Mountain Biking El Yeso Reservoir to Maipo Valley — Full-Day Tour from Santiago
Ride from El Yeso Reservoir high in the Andes down into the Maipo Valley on a full-day mountain bike tour from Santiago. Expect a 12-mile mixed-gravel descent, a scenic picnic at 2,500 m, and round-trip transfers from the city.
The Experience
Before You Go
Acclimate before the ride
Spend a morning in Santiago or a light afternoon hike nearby to reduce early-altitude effects—start the tour well rested and hydrated.
Tire pressure and punctures
Run slightly lower tire pressure for grip on gravel but carry a spare tube and a mini-pump—roads are remote and repairs take time.
Layer for temperature swings
Bring a lightweight windproof and an insulating mid-layer; mornings at 2,500 m are cold and the valley warms quickly.
Protect your eyes and skin
Sunglasses with UV protection and sunscreen are important—high-altitude sun is stronger and reflected off water and rock.
Local Knowledge
Hidden Gems

Conservation Note
The area is sensitive to erosion and water-quality issues—stick to established roads and trails, pack out waste, and avoid contaminating the reservoir used for city water.
Cajón del Maipo has long been a strategic mountain corridor supplying water and electricity to Santiago; El Yeso reservoir was built to regulate water flow and support the region’s needs.
