The Best Hot Springs in Arenal, Honestly Ranked

A straightforward, field-tested ranking of the hot springs around Arenal Volcano, from free river pools to developed resorts, with honest notes on what each offers.

Around Arenal Volcano, soaking in hot springs is not a luxury. It is a natural consequence of living next to an active volcano. Rainwater seeps deep into the ground, gets heated by the volcanic magma, and returns to the surface as warm, mineral-rich water. The result is a range of hot springs that vary from free river spots to polished resort pools.

This ranking comes from years of walking the riverbanks and testing the pools ourselves. We skip the hype and tell you what each place actually feels like. No affiliate links. No sponsored spots. Just honest advice for your visit.

1. Free River Hot Springs (Tabacon River and El Salto)

For the purest experience, head to the Tabacon River, just outside the national park. You can park along the road and walk down to the river. The water is naturally heated, and you can find your own spot among the smooth river rocks. It is free, public, and can get busy on weekends. Bring water shoes and a towel. The temperature varies by spot, so move around until you find your comfort zone.

Nearby, El Salto is a small swimming hole with a rope swing. The water is warm but not hot. It is more of a local hangout than a spa. Both spots are best in the late afternoon when the light softens and the crowd thins.

2. Tabacon Thermal Resort (Day Pass)

Tabacon is the most famous hot springs in the area, and for good reason. The resort channels the river water through a series of beautifully landscaped pools, waterfalls, and grottos. The water is clear, warm, and surrounded by lush jungle. A day pass gives you access to the entire complex from 10 a.m. to 6 p.m. or later. It is well maintained and feels like a tropical bathhouse.

The downside is the price. A day pass costs from $80 per person, indicative, and it can feel crowded during peak hours. If you want a polished experience with locker rooms, bars, and towel service, this is your best bet. If you prefer a quieter, more natural setting, skip it.

3. Baldi Hot Springs (Day Pass)

Baldi is a large complex with multiple pools of varying temperatures, from cool to very hot. It is family friendly, with waterslides and swim-up bars. The grounds are sprawling and can feel a bit theme-park-like. The water comes from the same volcanic source, but the experience is more about entertainment than nature.

A day pass costs from $40 per person, indicative. It is a good option if you are traveling with kids or want a lively afternoon. But if you are seeking quiet relaxation, this is not the place.

4. Los Lagos Hot Springs (Day Pass)

Los Lagos is a resort with a large thermal pool area, plus a lake, waterslides, and a small zoo. The hot springs pools are well maintained and offer good views of the volcano on clear days. The water temperature is consistent, and there are several pools to choose from.

A day pass costs from $35 per person, indicative. It is a solid mid-range option. The grounds are large, so you can find a quieter corner if you walk away from the main pool. The zoo is a minor attraction, not a highlight.

5. Eco Termales Hot Springs (Day Pass, Limited Capacity)

Eco Termales is smaller and more intimate than the big resorts. It has a handful of pools set in a garden, with a restaurant and a bar. The water is warm and clean. The key feature here is the limited capacity. They sell only a set number of day passes, so it never feels overcrowded.

A day pass costs from $50 per person, indicative. It is a good middle ground between the free river and the large resorts. The setting is pleasant but not dramatic. Book in advance, as spots fill up.

Your Next Step

Pick one hot spring that matches your style. If you want free and wild, go to the Tabacon River in the late afternoon. If you want a comfortable soak with amenities, choose Eco Termales for a quieter day or Tabacon for a full experience. Pack a towel, water shoes, and a reusable water bottle. Then go soak. Your muscles will thank you.
