Operated by Green Line Costa Rica · La Fortuna, Alajuela
Steam rises in slow, silvery ribbons from a ribbon of water that never cools — a thermal river cutting a warm line through tropical forest. Palms and ferns lean toward the current as if to taste the heat; the river answers by pushing gently, inviting guests into pockets of mineral-rich flow that have run from the volcanic bedrock for centuries.
moderate.
4 hours.
Best for people with good baseline fitness who can manage short hikes, uneven steps and standing in warm water for extended periods
The operator lists the activity at about four hours total, including arrival, a short rainforest walk, and time to soak in the thermal pools.
The river flows naturally from geothermal sources; many sites use built edges and steps to create shallow pools while keeping much of the experience in free-flowing channels.
Children can usually join but must be supervised at all times; check the operator’s age rules and be aware of very hot water in some spots.
This activity is not recommended for pregnant guests, people with serious heart conditions, or those with recent back/spinal injuries.
Thermal waters in the La Fortuna valley are a direct result of Arenal’s volcanic system; local communities have long used these springs for bathing and relaxation.
Avoid soaps, sunscreens and lotions in the water, pack out all trash, and follow marked paths to protect fragile riverside vegetation and water quality.
