Baldi Hot Springs is the largest thermal water complex in the Arenal region — 25 mineral pools fed by natural volcanic springs, ranging from cool refreshing tanks at around 20 °C to intense therapeutic pools above 62 °C, laid out across tropical gardens on the flank of Arenal Volcano. Your day pass gives you full unrestricted access to the pools, waterfalls, thermal slides and swim-up bars from opening to close, so you can pace the day exactly how you want it: sunset soak, post-hike recovery, or a full lazy afternoon between temperatures. Four pass options are available — Hot Springs only, Hot Springs + Lunch, Hot Springs + Dinner, or Hot Springs + Lunch and Dinner — so you can build the day around your itinerary. With meals, please tell us your preferred time when booking; the restaurant allows 60 minutes per meal. The complex is open daily from 9:00 AM to 10:00 PM, and nighttime soaking with volcano views is one of the signature La Fortuna experiences. Lockers, towels for rent, spa services and family-friendly zones with dedicated shallow pools are available on site. Ideal for travelers arriving after a long transfer, families with kids, couples on honeymoon, and anyone recovering from adventure days — a genuinely restorative anchor to the Arenal itinerary.
