25 thermal water pools filled by waterfalls and heated by Volcán Arenal all for your enjoyment. A day pass to Baldi gives you access to the oasis-like resort including the thermal pools, swim-up bars, waterslides, and cold plunges. There’s a little bit of everything for everyone here. Daypasses are available upon arrival and pricing varies depending on if you want lunch/dinner (outside food and drinks aren’t allowed). Towels + lockers are available for rent for an extra fee.
