The best hot springs in Arenal: where to soak in volcanic bliss
If you’re heading to La Fortuna and the majestic Arenal Volcano, you're entering the epicenter of Costa Rica’s hot springs scene. These thermal waters are naturally heated by the Arenal Volcano and infused with minerals that locals swear by. Whether you're into luxury spas or low-key river dips, Arenal has a steamy spot for every type of traveler.
Tabacón Thermal Resort & Spa
Price: $80+ for a day pass with lunch or dinner
Why go: It's the OG of Costa Rican hot springs. Picture lush tropical gardens, cascading thermal waterfalls, and dreamy pools that feel like they belong in a movie set.
Tip: It's fancy (and gets booked fast), so reserve in advance and go early if you want some peace before the crowds roll in.
Baldi Hot Springs
Price: Around $40 day pass
Why go: Family-friendly and full of energy. With over 25 pools, water slides, a swim-up bar, and neon-lit areas at night, it’s kind of like the Vegas of thermal baths
Micro-experience: I went on a Friday night and ended up doing cannonballs into a steamy pool under the stars. Would I do it again? Absolutely.
Ecotermales
Price: Around $45 with limited entry per day
Why go: Quieter, more intimate, and surrounded by dense jungle. No kids, fewer people, just peaceful mineral-rich water and bird songs.
Best for: Couples or solo travelers who want the spa vibe without the crowd.
Free option: Río Chollin
Price: Free!
Why go: This one’s for the adventurers. Located just outside the Tabacón resort, locals and backpackers love this spot. You’ll find thermal waters flowing through the jungle with rock pools built by bathers over the years.
Tip: Bring water shoes (it’s slippery), don’t leave anything in your car, and go during the day. There's no lighting, and it gets sketchy after dark.
Guanacaste's volcanic wonders: mud, steam, and jungle thrills
While Arenal gets most of the spotlight, Guanacaste is where hot springs meet adventure park vibes. Think bubbling volcanic mud, natural saunas in the forest, and thermal pools tucked into the landscape. It's rustic, wild, and surprisingly family-friendly.
Río Negro Hot Springs (Hacienda Guachipelín)
Price: ~$35 for hot springs access + mud bath, more if bundled with ziplining or horseback riding
Why go: You're soaking in river-fed pools surrounded by dense forest and volcanic rock. Before entering, slather yourself in warm volcanic mud, let it dry, then rinse off before dipping in.
Twist of tone: It’s like a spa treatment... if your spa was run by jungle elves.
Pro tip: Combine it with the Llanos de Cortés waterfall or a guided hike through Rincón de la Vieja National Park.
Las Hornillas
Price: ~$20 for entrance
What to expect: This spot near the Miravalles Volcano lets you wander through active geothermal terrain. There are bubbling mud pots, steam vents, a natural sauna, and of course, thermal pools.
Perfect for: Families with curious kids (science class meets spa day) or couples looking for a lesser-known spot to chill.
Thermomania (Bagaces)
Price: ~$25 day pass
Why go: A quirky, budget-friendly place with thermal pools, waterslides, mud baths, and even a small zoo.
Best for: Families or friend groups who want a mix of fun and relaxation on the cheap.
Hidden gems: hot springs beyond the usual trail
If you're the type who enjoys avoiding the crowds (or you just like finding cool places before they hit Instagram), Costa Rica has a few lesser-known hot springs that are totally worth the detour.
Eco Termales La Cangreja (Rincón de la Vieja area)
This one flies under the radar. It's a rustic set of thermal pools inside the jungle, sometimes only reachable via a short hike. No water slides. No crowds. Just pure nature and mineral-rich water.
Orosi Valley hot springs (Cartago Province)
While technically outside the usual Guanacaste or Arenal routes, these springs sit quietly in the lush central highlands. The scenery here is serene, with mountain views, and they’re often overlooked by foreign tourists.
Local tip: If you’re renting a car, don’t hesitate to stop at roadside signs that read “aguas termales”, some lead to family-owned springs on private land for a few bucks. It’s hit or miss, but sometimes you’ll get lucky with a thermal soak all to yourself.
When to visit Costa Rica’s hot springs
Best months: November to April (dry season). You’ll get better access to roads and won’t have to worry about muddy trails. Bonus: evening dips under clear skies are unforgettable.
Rainy season perk: From May to October, it might rain during the day, but that just makes the hot water feel that much better. Plus, it’s quieter.
Time of day: Go early morning for peace and birdsong. Or late afternoon for sunset colors and that jungle-night soundscape.
