2026 Guide to the Best Hot Springs in Guanacaste: Why Rincon’s Natural Thermal Pools Stand Out

- Chemically treated
- High visitor density
- Less connection to nature
Rincon’s Natural Thermal Experience
- True geothermal water; not heated artificially
- Flow-through system (fresh water constantly replaces old water)
- Natural landscaping: volcanic stone, river sounds, forest canopy
- Temperature variety for contrast therapy

How to Do the Volcanic Mud Bath (How-To Schema Compatible)
- Apply warm volcanic clay to skin
- Let it dry 15–20 minutes in the sun
