The Story Behind Arenal’s Hot Springs
Costa Rica sits along the Pacific Ring of Fire, home to more than 200 volcanic formations, and Arenal Volcano is one of the youngest and most geothermally active. Although Arenal has been in a resting phase since its last major eruption in 2010, the magma underneath the mountain still sits close enough to the surface to heat groundwater as it rises. Rainwater enters the earth through fissures, meets hot rock, absorbs minerals like silica, bicarbonate, and sulfur, then emerges at the surface anywhere from warm (around 27°C / 81°F) to very hot (over 40°C / 105°F).
The first commercial hot spring in the area was Tabacón, built on the path of the mountain-fed thermal river of the same name. Tabacón was the resort that put Arenal on the international wellness map in the 1990s. Once that happened, other developers followed, and over the next two decades the area turned into the densest concentration of hot spring resorts in Central America.
What makes Arenal’s springs different from many thermal destinations around the world is the setting. You’re not soaking in a spa basement. You’re soaking in the rainforest, often under a volcano view, surrounded by flowering heliconias, kingfishers, and (more often than people expect) the occasional coati wandering past.
What to See & Do at Arenal’s Hot Springs
Most visitors pick one or two resorts that match their budget and style. Here’s how the main options break down.
- Luxury and romance: Tabacón Thermal Resort & Spa. The original, and still the most atmospheric. Five cascading pools fed by a real thermal river (the only one of its kind in Arenal), impeccable tropical landscaping, and an adults-only section. Day passes run roughly $85–$105.
- Luxury with a view: The Springs Resort & Spa. A sprawling hillside property with dozens of pools at different temperatures, swim-up bars, waterfalls, and the most dramatic volcano views of any resort. Day passes are valid for two consecutive days, around $124–$141 per person.
- Boutique and intimate: Ecotermales La Fortuna. The smallest of the serious resorts, with five pools and a strict cap of 100 visitors per time slot. This is the option for travelers who want quiet. Around $49 per adult, or about $81 with a meal.
- Classic mid-range: Paradise Hot Springs. Beautifully designed mineral pools, hydro-massage stations, and a calmer vibe than Baldi. A solid middle option.
- Family and energy: Baldi Hot Springs. 25+ pools, waterslides, swim-up bars, sauna, and a kids’ play zone. The busiest property in Arenal, and the most fun if you’re traveling with children or a group of friends. Day passes start around $40.
- Free soak: Río Chollín. A short walk from a small bridge on Route 142, just past Tabacón, where the same thermal river flows through a public stretch of riverbed. No facilities, no fee, water shoes recommended because the stones are slippery. The worst-kept secret in La Fortuna.
- Budget option: Termales Los Laureles. The cheapest official hot spring in the area, popular with Costa Rican families. Four simple pools, one slide, and a killer volcano view. Bring your own food and drinks.
Most travelers pair a hot spring soak with a morning of hiking or a waterfall visit. That sequence (active day → hot soak → dinner) is the classic Arenal rhythm, and it’s popular for a reason.
