Quick answer: Arenal has 14 hot springs properties ranging from $12 to $140 per person. For luxury couples, Tabacon (~$110) delivers the best overall ambiance. Families should look at Kalambu (waterslides, ~$40) or Baldi (variety). Budget travelers can visit the free Chollin river pools. For a quiet, intimate soak, Ecotermales (~$49) caps visitor numbers. Most travelers only need one hot springs visit of 2 to 3 hours, ideally scheduled for the evening after a day of hiking or adventure.
Choosing between 14 hot springs is the kind of decision that eats an hour of your trip planning and shouldn’t. We have visited every hot springs property in the Arenal area, most of them multiple times with different clients. This guide cuts through the noise and tells you exactly which one fits your trip.

How Do Arenal Hot Springs Work?
Quick answer: Arenal Volcano sits above a massive underground aquifer roughly half a mile wide and 0.6 miles deep. Geothermal activity heats this water, which then flows naturally or is pumped to 14 hot springs properties in the area. Pool temperatures range from 28 to 41 degrees Celsius (83 to 104 degrees Fahrenheit). The mineral content is high in bicarbonate and chlorides, low in sulfur, which means therapeutic skin benefits without the rotten-egg smell.
Most hot springs properties offer multiple pools at different temperatures, so you can move between warm and cool water throughout your visit. Some include swim-up bars, in-pool waterfalls, and poolside dining. Day passes typically cover 4 to 6 hours of access, though evening passes (5 PM to 9 or 10 PM) are also available at many properties.
What to Bring
Swimsuit, water shoes (rocky bottoms in some pools), a waterproof phone case, sunscreen if visiting during the day, and a towel (some properties provide towels, others charge $2 to rent). Leave valuables in your hotel safe. Most properties have lockers.
Best Time to Visit
Evening, without question. The heat of the day makes hot water less appealing. Between 5 and 9 PM, the ambient lighting at properties like Tabacon and Baldi transforms the experience. Fewer crowds on weekdays. If you are combining hot springs with a daytime activity, schedule your adventure in the morning and hot springs after 4 PM.
The Luxury Hot Springs
Tabacon Thermal Resort (~$110/person)
Tabacon is the most famous hot springs in Costa Rica for a reason. The landscaping is immaculate, the thermal river flowing through the property feels completely natural, and the Shangri-La Gardens section is adults-only. Five pools at varying temperatures, a cold river plunge option, and a waterfall you can sit under. Day passes include access from 10 AM to 10 PM, and meal packages are available for an additional cost. Reservations are essential. In high season, Tabacon sells out 2 to 3 weeks in advance. Located 13 km from La Fortuna town on the road toward the national park.
Dallas’s tip: If you are going to Tabacon, go in the evening. The ambient lighting after sunset is what makes this place special. The dinner combo package sounds good on paper but it is a lot of food served late. We usually tell clients to skip the meal package, eat a late lunch in La Fortuna, then just enjoy the pools and order a drink at the swim-up bar.
The Springs Resort & Spa (~$75 to $140/person)
The Springs has the best volcano views of any hot springs in Arenal. 18 thermal pools cascading down a hillside, multiple restaurants (including a sushi bar), and a full spa. Day pass availability is limited because hotel guests get priority. Book 2 to 3 weeks ahead and confirm availability on their website. The property is enormous, so even on busy days it does not feel crowded. The two-day pass option is good value if you are staying in the area for multiple nights.
The Mid-Range Hot Springs
Baldi Hot Springs (~$40 to $65/person)
Baldi is the largest hot springs complex in Arenal with 25 thermal pools across a sprawling property. Good variety: some pools are quiet and secluded, others have waterslides and swim-up bars. Volcano views from several pools. This is the most versatile option if your group has mixed preferences. Day pass is valid all day (10 AM to 10 PM), which gives you flexibility. The trade-off is that Baldi can feel commercial and crowded during peak season.
Ecotermales (~$49/person)
This is the hot springs we recommend most often for travelers who want something peaceful. Ecotermales is family-owned and caps the number of visitors at any given time, so it never feels packed. Four pools at different temperatures in a natural setting. No waterslides, no swim-up bars, no loud music. Just warm water, tropical plants, and quiet. Day pass runs 10 AM to 4 PM. Night pass runs 5 PM to 9:30 PM. Nine-minute drive from La Fortuna.
Paradise Hot Springs (~$40/person)
Paradise is our pick for best value in the mid-range category. Seven thermal pools ranging from 35 to 41 degrees Celsius, all fed by natural mineral water. The property uses the pools for hydrotherapy, so you will find water jets and waterfalls designed for different body areas. Numbers are restricted to maintain a peaceful atmosphere. Towels and lockers included. A cold pool provides contrast therapy. Less well-known than Baldi or Tabacon, which keeps it quieter.
Los Lagos Hot Springs (~$52/person with meal)
Los Lagos is part of a larger hotel and resort complex that also includes waterslides, a lake, and walking trails. The volcano views from the property are excellent. A solid option for families who want hot springs plus other activities in one location. The day pass includes a meal, which adds value. Waterslide access is part of the package. Open 10 AM to 10 PM.
Titoku Hot Springs (~$33 to $52/person)
The smallest hot springs in Arenal with just 8 pools and a maximum capacity of 80 guests. If you are staying at Arenal Kioro hotel, access to Titoku is free. For day pass visitors, the intimate size means you often have pools to yourself, especially on weekdays. Reservations required by phone. Eight-minute drive from La Fortuna.
Budget and Free Hot Springs
Chollin River (Free)
Also known as El Choyin, this is a natural thermal river just steps from Tabacon’s parking lot. No facilities, no changing rooms, no lifeguards. You park on the roadside, walk down a steep, sometimes muddy trail for 5 to 10 minutes, and reach a riverbed where hot volcanic water mixes with cold river water. The temperature varies by spot. Bring water shoes, watch your footing, and be comfortable with a completely unmanaged environment. Free and authentic, but not for everyone.
Hot Springs Pura Vida (~$10 to $15/person)
An official section of the Tabacon river downstream from the resort, on the other side of the bridge. Same thermal water, much lower price. Basic facilities. A good compromise between free river pools and a commercial property.
Los Laureles (~$12/person)
The most affordable commercial hot springs in the area. You are welcome to bring your own food, which keeps the total cost very low. Popular with locals, which is always a good sign. Relaxed atmosphere, basic facilities, genuine thermal water.
Hot Springs and Kids: What Parents Need to Know
Quick answer: Kalambu is the best hot springs for families with young children (waterslides, shallow pools, water cannons). Baldi also works well with its 25 pools including kid-friendly options. Tabacon allows children but has strict rules about noise and splashing. The Springs Resort has a good balance of family pools and quiet adult areas. Avoid the free river pools with small children due to uneven terrain and lack of safety infrastructure.
Most commercial hot springs have changing rooms, showers, and lockers suitable for families. Water shoes are recommended for all children. Bring plenty of water to drink as thermal pools cause dehydration faster than regular swimming. Set a time limit of 2 hours maximum for kids in hot water, and make sure they alternate between warm and cool pools.
Can You Visit More Than One Hot Springs in a Day?
Quick answer: Physically possible, but we do not recommend it. Extended thermal exposure causes dehydration and diminishing returns on relaxation. Pick one property, enjoy 2 to 3 hours there, and spend the rest of your day on other Arenal activities. One well-chosen hot springs visit beats two rushed ones every time.
How to Book Arenal Hot Springs
Most properties accept walk-ins during low season (May to November). In high season (December to April), book in advance. Tabacon sells out 2 to 3 weeks ahead. The Springs Resort day passes are limited and should be checked on their website. Ecotermales has fixed time slots (day and night) that fill up.
When we plan Arenal trips for our clients, we include hot springs in the itinerary and handle the booking. We match the right property to your traveler type so you don’t have to sort through 14 options yourself.
Frequently Asked Questions
Are Arenal hot springs natural?
The thermal water is natural, heated by geothermal activity beneath Arenal Volcano. Some properties use pools fed directly by natural thermal rivers (Tabacon, Chollin). Others pump heated water from the underground aquifer into constructed pools. Both deliver the same mineral-rich water with therapeutic benefits.
Do hot springs smell like sulfur?
Arenal’s thermal water is high in bicarbonate and chlorides but low in sulfur, so there is minimal to no sulfur smell. This is different from hot springs in places like Iceland or Yellowstone where sulfur content is much higher.
Can you visit hot springs if you are pregnant?
Most medical guidelines recommend pregnant women avoid water above 38 degrees Celsius (100 degrees Fahrenheit). Several Arenal hot springs have cooler pools (28 to 35 degrees Celsius) that may be suitable, but consult your doctor before visiting. Tabacon and Baldi both have cooler pool options.
Which hot springs have the best food?
Tabacon’s restaurant is the best on-site dining of any hot springs property. The Springs Resort has multiple restaurants including a sushi bar. Baldi offers a buffet dinner option. For the best food in the area overall, eat in La Fortuna town and keep your hot springs visit focused on the water.
Are hot springs open when it rains?
Yes. All commercial hot springs operate rain or shine. Rain actually enhances the experience. Sitting in warm thermal water while tropical rain falls around you is one of the most memorable sensory experiences in Costa Rica. Evening rain visits are particularly atmospheric.
