EcoTermales Hot Springs in Arenal: Our Favorite for Pure, Natural Thermal Relaxation Without the Crowds

When our guests want to step away from high-octane adventure and truly unwind in pure, mineral-rich thermal waters, we always point them toward Ecotermales Fortuna.

Unlike the massive, sprawling waterpark-style resorts in the area, Ecotermales offers a completely different vibe. It is a family-owned, boutique property nestled right in the jungle, designed to feel intimate, natural, and deeply relaxing. With completely natural hot springs heated directly by the Arenal Volcano, it is our absolute top recommendation for wellness and pure peace.

What to Know Before You Go

• Who is it for?: Perfect for couples, honeymooners, adults, and anyone looking for a tranquil, upscale, and uncrowded soaking experience surrounded by lush rainforest.
• The main highlight: The thermal pools themselves. The water flows naturally through different temperature pools ranging from warm to hot, surrounded by dense tropical foliage. Because they strictly limit daily visitor capacity, you never have to fight for a spot or feel like you're in a crowded public pool.
• What others won't tell you (And we will): Because Ecotermales prioritizes a peaceful, relaxing environment, they have strict rules to maintain that tranquility (for instance, they don't allow loud groups or boisterous parties). Also, because visitor caps are enforced to keep the experience exclusive, booking ahead is a must—they frequently sell out.

Tour Details

• Duration: Flexible pass options (typically day passes or evening passes, often paired with lunch or dinner at their on-site traditional restaurant).
• What's included: Access to the natural thermal pools, changing rooms, and secure facilities (with dining options available depending on the pass you choose).
• What we suggest bringing: Swimwear, sandals or water shoes, a change of clothes, a towel, and casual clothing for dining if you stay for a meal.

How to Fit This Into Your Trip

Because an afternoon or evening soak at Ecotermales is the ultimate way to melt away fatigue, our guests love scheduling this right after a big adventure day (like hiking the volcano or walking the hanging bridges) to completely reset their bodies.
