The nearest volcanic hot springs are under an hour from Liberia airport (LIR). Most sit on the slopes of Rincón de la Vieja, the rest around Miravalles near Bagaces, and nearly all of them offer a volcanic mud bath. They range from rustic riverside pools to adventure parks with ziplines and waterslides to quiet eco-lodges. Here they are side by side, with the drive from the airport.

Volcano check (September 2026): Rincón de la Vieja is on alert level 3 ("caution") and has been erupting frequently since July. Communities around the park, including Dos Ríos, Cañas Dulces and Curubandé, are on a precautionary green alert, and the Río Azul, near Blue River Resort, is one of the rivers being watched for mudflows. It isn't a closure, but check our volcano status notes and ask your hot spring whether it's operating normally before you drive up.
Which one should you pick?
- The classic: Río Negro. Natural pools along a river, a real volcanic mud bath and a 1.5-hour visit that fits after a morning at Las Pailas. As of September 2026, official prices are $35 for adults and $30 for children 4 to 12; buy online or at the hacienda in advance, as space is limited.
- A full day with kids: Rincon Thermals & Adventures or Buena Vista del Rincón, where the hot springs come with ziplines, horses and a big waterslide.
- A night at a hot springs resort: Borinquen, or Blue River if you want somewhere remote.
- Adults, nature, quiet: Río Perdido, where the river itself is the hot spring.
- Something different: Las Hornillas, where you walk through the steaming heart of Miravalles before you soak.
Insider tip: If you only have one afternoon, I'd pair the Las Pailas trail at Rincón de la Vieja with a soak and mud bath at Río Negro nearby. Go on a weekday if you can, and remember the national park is closed on Mondays.
What a mud bath is like
At Río Negro, the mud comes straight from the ground where the hot water bubbles up: a soupy gray mud full of volcanic minerals such as sulfur, magnesium and zinc. The routine is the same at most places:
- Shower, then warm up with about 10 minutes in a hot pool.
- Paint it on. Spread a thin layer over your face and body (a partner helps with your back).
- Let it dry, usually 10 to 15 minutes. You'll feel it tighten and crack.
- Rinse it off in the river or the showers.
- Soak. Now move on to the thermal pools.
The whole ritual takes 20 to 30 minutes. Your skin will feel soft and a little tight afterward, so moisturize after your last shower. People believe the minerals are good for your skin; mostly, it's just a lot of fun.
What to bring
- A swimsuit you don't mind staining (dark is best)
- Water shoes or sandals for rocky riverbanks and wet steps
- A dry change of clothes, sunscreen and bug spray
- Drinking water
- A few hundred colones in cash for the private road toll on the way to Río Negro (about 800 colones)
Río Negro has changing rooms, lockers and showers and provides towels. Elsewhere, check whether towels are included.
How long to soak, and staying safe
- Short sessions. Keep each soak to about 15 to 20 minutes, less in the hottest pools, then cool off and drink water. Hot water and Guanacaste sun dehydrate you quickly.
- Skip the alcohol while you soak, even if there's a swim-up bar.
- Pregnant, or have a heart condition? Ask your doctor first. General hot-tub advice is to avoid long, very hot soaks during pregnancy, and hot water lowers blood pressure and raises your heart rate.
- Skip the mud if you have open cuts, sunburn or very sensitive skin.
- Keep your head above the water. The CDC recommends it in any natural hot spring because of a very rare water-borne infection.
- Mind the volcano. In 2026, stay out of riverbeds on Rincón de la Vieja's flanks and follow any closures.
Combine it with your transfer
Río Negro and the other Rincón de la Vieja springs are under an hour from Liberia airport, and the Miravalles springs are north of Bagaces, just off the highway toward Cañas and Arenal. So a soak can fit into your drive from the airport, especially if you're heading to a lodge near the volcano or on to La Fortuna. Every Anywhere private transfer includes up to an hour of stops. A hot springs visit usually takes longer, so ask about adding a stop when you book. See Liberia airport to Rincón de la Vieja, Liberia airport to La Fortuna and all our private transfers from LIR.

Frequently asked questions
Do you wear a bathing suit in a mud bath?
Yes. The mud baths around Rincón de la Vieja and Miravalles are outdoors, next to other bathers, so you wear a swimsuit. Pick an old or dark one, because the minerals can stain light fabric. Bring a dry change of clothes for the ride back; most places have changing rooms and showers.
Are mud baths worth it?
If you're near Rincón de la Vieja or Miravalles anyway, yes. It's a fun, slightly silly hour: you paint each other gray, wait for the mud to dry and crack, rinse in the river and sink into a hot pool. Kids love it. Keep your expectations rustic, though. These are natural pools in the forest, not a luxury spa.
How long should you leave the mud on?
Until it dries, usually 10 to 15 minutes. You'll feel it tighten on your skin. Then rinse it off in the river or the showers before you get into the thermal pools. The whole ritual takes 20 to 30 minutes.
How long should you soak in hot springs?
About 15 to 20 minutes at a time, less in the hottest pools. Then get out, cool off (the cold river is perfect), drink some water and go back in. Hot water dehydrates you faster than you'd think, especially in the Guanacaste heat.
Are mud baths hygienic?
At Río Negro, the mud is dug from the volcanic ground where the hot water bubbles up, and you rinse it off in the river or a shower before you get into the thermal pools. As with any natural hot spring, keep your head above the water; the CDC recommends this because of a very rare water-borne infection.
Is it safe to swim in hot springs in Costa Rica?
Generally yes, with a few precautions. Soak in short sessions, drink water, skip alcohol while soaking, and keep your head above the water. Check with your doctor first if you're pregnant or have a heart condition. In 2026, also check the Rincón de la Vieja volcano status and stay out of the riverbeds on the volcano's flanks.
Which hot springs near Liberia are best for kids?
Río Negro (children's tickets from age 4, under 4 free), Rincon Thermals & Adventures (the Nature Pass is for all ages), Buena Vista del Rincón and Blue River, which both have big waterslides, and Yökö Termales, which has a children's pool. Río Perdido only accepts guests aged 8 and up.
