Free Hot Spring River (El Chollín)
Soak in the authentic thermal currents flowing directly from the thermal veins of the Arenal Volcano, surrounded by dense tropical jungle.
Experience the Natural Flow of Arenal
El Chollín is the famous local hot spring river where the geothermal warmth of the volcano meets the crisp natural rainforest currents. Unlike artificial resort pools, this river features completely raw, unaltered warm thermal flows where visitors can sit among natural volcanic boulders and enjoy a soothing massage from nature's streams.
Located just a short ride outside La Fortuna center, this local sanctuary represents the true spirit of Costa Rica's natural wonders. The crisp rainforest air combined with the steamy, mineral-rich warm water forms the ultimate sanctuary to recover after a long day of volcanic hiking or zip-lining adventures.
