Volcano views by day. Warm mineral water by night.
Make it your own
Treat hot springs as the unwind half of an Arenal day: morning trail, hanging bridges, or waterfall; afternoon or evening soak. Resort-style day passes (think Tabacón-area thermal river gardens) feel landscaped and meal-friendly; places like Eco Termales emphasize capped sessions and a quieter spa mood; larger complexes such as Baldi lean family amenities and many pools. Names here are place markers for style—not reviews, star ratings, or price quotes. Pair same-region canopy at costaricacanopy.com and park days at naturacostarica.com.
Before you go
Base in La Fortuna town or along the road toward Lake Arenal / the volcano flanks. Confirm day-pass hours, meal inclusions, age rules, and towel/locker policies with the operator—availability can be limited and advance booking is often recommended at popular properties. Bring water shoes, a dry change of clothes, and reef-safe or gentle products if you use sunscreen before soaking. Do not rely on any static price you see elsewhere; check live offers when you book. Beyond Arenal, Guanacaste’s Río Negro springs near Rincón de la Vieja are a separate trip—see Plan.
