More ways to explore the area's outdoor wonders
A misty trail opens onto blue so vivid it seems painted: Rio Celeste cuts through old-growth forest beneath the slopes of Tenorio Volcano, the water daring you to follow its curve. Guides lead small groups along root-laced paths and wooden walkways, the air humid and punctuated by bird calls. Sunlight filters through broadleaf canopy as insects and distant howler monkeys claim the silence.
