Tabacón Thermal Resort & Spa: The Crown Jewel (Website)

One of the most famous hot springs near Lake Arenal is found at Tabacón Thermal Resort & Spa, located just a short drive from the lake on the road toward La Fortuna. Often considered the gold standard of thermal experiences in Costa Rica, Tabacón is a sprawling oasis where nature and luxury intertwine. The resort features a series of cascading pools fed by the Tabacón River, which flows naturally from the volcano’s base. Temperatures range from a mild 77°F to a steamy 102°F, allowing visitors to find their perfect level of warmth.

What sets Tabacón apart is its commitment to preserving the natural environment. The pools are surrounded by lush gardens filled with tropical flora, and the water is 100% natural, free from artificial heating or pumping. The resort’s design mimics the flow of the river, with hidden nooks, waterfalls, and even a swim-up bar for those who fancy a cocktail while soaking. A half-day pass, including a meal, starts at around $70 per person, though booking in advance is wise during peak seasons like December to April. While it’s a bit pricier than other options, the serene ambiance and stunning views of Arenal Volcano make it worth every penny.

Baldi Hot Springs: Family Fun Meets Relaxation (Website)

For those traveling with family or seeking a livelier atmosphere, Baldi Hot Springs is another excellent choice near Lake Arenal.

Baldi’s affordability—entry starts at $35 per person, or $57 with a meal—makes it accessible to a wide range of travelers. The sprawling grounds are dotted with tropical plants, and the pools offer unobstructed views of the volcano on clear days. While it can get busy, especially during high season, the sheer variety of pools ensures there’s always a spot to unwind. It’s less intimate than some alternatives, but if you’re after a blend of relaxation and excitement, Baldi delivers.

If tranquility is your goal, Eco Termales offers a more intimate experience. Situated a short drive from Lake Arenal near La Fortuna, this family-owned gem limits visitors to 100 at a time, ensuring a peaceful soak surrounded by nature. The five thermal pools here range from 99°F to 106°F, with waterfalls connecting them amid a rainforest setting that feels like a secret hideaway.

Eco Termales emphasizes simplicity and authenticity. There are no flashy amenities—just warm, mineral-rich waters, a cozy restaurant serving traditional Costa Rican fare, and trails winding through the lush grounds. Entry starts at $40, or $62 with a meal, making it a mid-range option that feels exclusive without breaking the bank. The limited capacity means reservations are a must, but the reward is a serene escape where you can hear the rustle of leaves and the calls of tropical birds as you soak.

Río Chollín: Nature’s Free Gift (Website)

For budget-conscious travelers or those craving a raw, natural experience, Río Chollín (also known as Tabaconcito) is a hidden treasure near Lake Arenal. Located just steps from Tabacón, this free, public hot spring is a natural river pool where geothermal waters mix with cooler currents, creating a range of temperatures up to 104°F. It’s a favorite among locals and adventurous visitors alike, with shallow areas for wading and deeper pools for soaking.

There’s no entry fee, though parking on the roadside might involve a small tip to locals who watch your car. The setting is unpolished—think rocks, trees, and the sound of flowing water rather than manicured gardens—but that’s part of its charm. Water shoes are recommended due to the rocky terrain, and it’s wise to visit during daylight for safety. Río Chollín offers a no-frills way to enjoy the region’s geothermal wonders, with Lake Arenal just a short drive away for a post-soak cool-off.
