The Arenal resort most identified with the destination — Tabacón, where a volcanic thermal river flows naturally through 12 hectares of tropical gardens at 72–105°F. The only property in the region where the water is a genuine flowing river rather than channeled pools. Carbon-neutral certified. Two restaurants, a swim-up bar inside the thermal river, and an adults-only Shangri-La garden section. Day pass from $80.
Why We Chose It
Tabacón was one of the first hot springs resorts in Arenal and remains the most photographed — the thermal river winding through lush plantings with the volcano framing the view is the image most associated with Arenal globally. Hotel guests have unlimited river access. Day pass visitors book morning or afternoon slots.
What Stands Out
- Only natural thermal river in Arenal — volcanic water flows constantly, not pumped
- Temperatures 72–105°F through 12 hectares of tropical gardens
- Volcano views while soaking — the iconic Arenal photograph
- Carbon-neutral certified
- Day pass from $80 — most popular non-hotel hot springs entry
