Cachi
A scenic artificial reservoir located in the Ujarrás Valley of Cartago Province
Lago Cachí is a tranquil artificial reservoir cradled in the Ujarrás Valley, its glassy surface reflecting the verdant mountains and agricultural terraces that rise from its shores. Created by the Cachí Hydroelectric Dam across the Reventazón River, this engineering landmark has become one of Costa Rica's most serene water-based destinations, offering crystalline views of the surrounding Orosí Valley. The lake sits at 970 meters elevation, providing a temperate climate ideal for leisurely exploration throughout the year. Best visited during dry seasons (December-April, July-August) when mountain vistas are clearest, the area invites both contemplative moments and active recreation along its scenic periphery.
Kayak or paddle on glassy water surrounded by steep hillsides and agricultural terraces, with the Cachí Arch Dam visible across the reservoir. Photograph sunrise reflections, misty mountain landscapes, and the Ujarrás Valley from scenic viewpoints along the lake's periphery; best light and clarity occur during dry seasons (December–April, July–August). Plan a scenic drive connecting Cartago, Paraíso, Cachí, and Orosí through countryside, and pair the lake visit with nearby Ruinas de Ujarrás and Orosí Valley exploration.
Best Time to Visit
December through April (dry season) offers the clearest views of the lake and surrounding volcanic landscape, with mornings before 10am typically providing the best visibility before afternoon clouds roll in. May through November (green season) brings lush vegetation and fewer tourists, though afternoon rain is common; mornings are still usually clear and the lake is more vibrant. Visit on weekdays to avoid San José day-trippers who concentrate here on weekends.
What Changes Through The Year
Dry Season (Dec–Apr)
Mountain vistas are clearest and photography conditions are optimal; easier road travel to viewpoints.
Green Season (May–Nov)
Hillsides are lush and green with dramatic clouds and mist; higher water levels create excellent landscape photography opportunities.
Getting There
From Cartago city center, head southeast toward Paraíso and continue toward the Orosí Valley. The lake is accessible via the main road through Cachi/Orosí. From San José, take the Pan-American Highway south toward Cartago, then follow signs to Orosí Valley.
What to Bring
Safety Considerations
Who This Is For
“The best viewpoint of the lake and dam is from the Cachí Dam overlook area near the power plant entrance, which offers clearer vistas than most lakeside spots and requires minimal walking. Visit early morning (before 9 AM) when tour groups from nearby towns haven't yet arrived, ensuring quieter conditions and better mountain reflections.”
