Tabacón Thermal Resort & Spa - The River That Fell Out of a Volcano

There's a river running through this resort that no engineer designed. It seeps out of the earth at the base of Arenal Volcano, picks up heat and minerals from somewhere deep underground, and winds through 7,790 sq m (83,880 sq ft) of rainforest garden before you even get to stick a toe in it.

Tabacón Thermal Resort & Spa, about 15 minutes outside La Fortuna in Costa Rica's northern lowlands, has built its entire identity around that fact - and honestly, it has a point. Twenty-three pools and cascading waterfalls, all fed by water that's never been reheated or recycled, ranging from a comfortable 22°C to a serious 38°C (72°F to 100°F). You can float in volcanic water under a tropical downpour while toucans do whatever toucans do nearby.

The food is serious enough that locals from La Fortuna drive out here specifically to eat. The spa operates outdoors, in bungalows open to the forest. And a handful of suites come with private plunge pools fed by the same geothermal source. It's a lot to take in.

Location

Tabacón sits 13 km (8 miles) northwest of La Fortuna, along the road that leads toward Arenal Volcano National Park. The volcano - 1,633 m (5,358 ft), perfectly conical, dormant since 2010 but still radiating a kind of geological authority - sits right there in your sightline from most of the property. The resort protects over 230 hectares (570 acres) of private rainforest reserve surrounding it.

La Fortuna is the main hub for visitors to the Arenal region: a lively small town ringed by waterfalls, rivers, and trails, with a strong reputation for adventure tourism. From here you can access kayaking on Lake Arenal (Costa Rica's largest lake, stretching along the volcano's western base), zip-lining through the canopy, canyoning, wildlife encounters, and the lava fields inside Arenal Volcano National Park itself. The park entrance fees go directly toward the country's system of protected areas, which cover over 25% of Costa Rica's total territory.

Getting here from either of Costa Rica's main international airports - Juan Santamaría (SJO) in San José or Daniel Oduber (LIR) in Liberia - takes roughly 2.5 to 3 hours by road. There's also a daily domestic flight from San José to La Fortuna's local airstrip, which puts you about 30 minutes from the resort.

The Story

The founders discovered this land in the late 1980s, drawn by the thermal springs that were already emerging naturally from the earth. Their concept was straightforward in theory, harder to execute in practice: build something worthy of the landscape without ruining it. Tabacón has been operating for over three decades, which in the context of Costa Rican eco-tourism is a considerable track record.

The architecture is designed to minimize environmental impact. Cuisine is built around locally sourced and seasonal ingredients. There are active reforestation programs on the property. The thermal river is never chemically treated or artificially heated - it flows as it always has, naturally renewed by volcanic activity.

Food & Drinks

Tabacón runs five distinct food and drink venues across the property, ranging from a fine-dining restaurant to a swim-up bar where you order cocktails while sitting in a thermal pool. The culinary program is overseen by Culinary Director Chef Saúl, whose cooking philosophy is rooted in Costa Rican ingredients and heritage while incorporating influences that reflect the country's multicultural history - including Afro-Caribbean and subtle Asian inflections that have been part of Costa Rican cooking for well over a century.

Saúl grew up cooking with his grandmother over a wood-burning stove in Cartago and learned his love of seafood from his uncle, one of the country's early tuna fishermen. He refuses to use imported seafood when local alternatives exist, and the kitchen works with small regional suppliers throughout.

Tucanes Restaurant

This is the resort's flagship, and it's a place that justifies the drive from La Fortuna on its own. Tucanes operates as an open-air fine-dining room under the rainforest canopy, combining Costa Rican ingredients with sophisticated technique.

The menu reads like a serious kitchen taking its sourcing as seriously as its plating: raw preparations include tuna tartare with cured egg yolk and ponzu, and a squash leche de tigre ceviche with avocado emulsion and crispy corn.

From the sea, the catch of the day comes with huancaína potato purée and coconut curry sauce. Land dishes include a lamb rack with blue cheese polenta and a Wagyu burger on brioche with truffle aioli and caramelized onions.

On the heavier end, a Tomahawk arrives with roasted baby potatoes, chimichurri, sweet plantain, and corn on the cob. Desserts are house-made and include a matcha tiramisu, a passion fruit and coconut pavlova, and a house gelato sampler.

Agua Ardiente Pool Bar

The original swim-up bar, positioned directly in the thermal springs. You sit in warm volcanic water and someone hands you a tropical cocktail.

Shangri-La Bar

Nestled within the adults-only Shangri-La section of the property (more on that below), this bar goes well beyond a drinks list. The food menu includes Thai ceviche, spring rolls, fresh tuna salad, wraps, bowls, and burgers - a more casual and globally inflected offering than Tucanes, suited to a long afternoon. The cocktails lean into creative tropical mixology.

Cana Brava Bar

At the center of the resort, Caña Brava operates as a lounge bar serving specialty cocktails alongside tapas and fuller meals. It overlooks the tropical gardens and works at any time of day - whether you're killing time before your spa appointment or settling in for an evening with friends.

Coffee Tasting

Costa Rica is one of the world's serious coffee-producing nations, and Tabacón offers a structured coffee tasting experience that takes you from bean to cup, working through different Costa Rican varieties paired with freshly made pastries. Given the country's agricultural heritage and the quality of what's grown in its highlands, this is worth doing even if you think you already know coffee.

The Rooms

The resort has 105 rooms and suites across several categories, all incorporating natural materials, Costa Rican craftsmanship, and either rainforest or volcano views. Every stay includes unlimited access to the thermal springs.

Rainforest Room

At 62 sq m (667 sq ft), this adults-only room centers on a king bed dressed in quality linens and surrounded by handcrafted Costa Rican furniture. The interior design is sophisticated without being cold - there's a warmth to the use of local materials that keeps it from feeling like a generic luxury hotel room. A 42-inch flat-screen TV, coffee and tea service, and Wi-Fi are included.

A bathtub and a separate glass-enclosed shower. The light and finishes continue the natural material palette from the bedroom. The private terrace is the real draw: panoramic views of the jungle, with enough space to actually use it rather than just look at it.

Tabacón Suite

The largest single-room category on the property at roughly 100 sq m (1,076 sq ft), the Tabacón Suite fits a king bed, a sofa bed, and generous seating and dining areas into a space that still manages to breathe. Expansive windows frame the rainforest views. There's a 42-inch TV in the bedroom and a 26-inch screen in the bathroom - an unusual touch that makes more sense once you've spent a morning soaking in the in-room Jacuzzi.

A private terrace opening onto the rainforest. The glass-enclosed hot spring shower is a distinct feature here - it's essentially bringing the thermal experience into the room itself, with views of the surrounding landscape while you're in it.

Volcano View Suite

At 70 sq m (753 sq ft), this adults-only suite is clearly designed with couples in mind. The king bed and spa-style interiors create an atmosphere of deliberate calm - every detail moves in the same direction. A deep soaking bathtub and dual rain shower in the bathroom give you options, and the suite includes a 50-inch TV, coffee and tea service, and Wi-Fi.

The private balcony delivers what the name promises: direct views of Arenal Volcano and the rainforest. In the mornings, when the clouds that wrap the volcano overnight begin to lift and the light shifts, this is an extraordinary thing to watch with coffee in hand.

The sounds of the forest and flowing water provide what the resort accurately describes as a natural soundtrack. This is the suite for honeymoons, anniversaries, or anyone who wants their physical surroundings to do some emotional heavy lifting.

Private Pool Suite

Also 70 sq m (753 sq ft), adults-only, with a king bed in fine linens and a design that balances contemporary elegance with distinctly Costa Rican character. Dual rain shower in the bathroom. The 50-inch TV, coffee and tea service, and Wi-Fi are standard inclusions. The design is quieter and more private-feeling than some of the other categories.

Here is where this suite separates itself: a private plunge pool on the terrace, fed by Tabacón's mineral-rich thermal waters. The same geothermal source that supplies the main hot springs complex feeds your private pool. Garden and rainforest views frame the space.

You can start your morning with a dip before the rest of the property wakes up, or stay in until late evening watching the Arenal landscape shift in the fading light.

The Spa

The spa uses volcanic clay, tropical fruits, and native Costa Rican botanicals - cacao, aloe, pineapple - alongside mineral-rich thermal mud. Treatments are developed specifically for the resort under the label "Autograph Treatments," drawing on the volcanic energy and local ingredient tradition of the region.

The spa also maintains an open-air yoga deck where certified instructors lead sessions. Complementary yoga sessions are included for hotel guests, subject to availability. The setting - a raised platform surrounded by rainforest - turns a standard practice into something considerably more atmospheric.

When you arrive at the spa, you're welcomed with herbal infusions and tropical fruits before treatment.

The treatment bungalows are open-air structures, so the sounds of the rainforest, the warmth of the air, and the ambient presence of the thermal river are all part of the experience rather than something you escape from.

Shangri-La Gardens

Shangri-La Gardens is the adults-only section of the thermal experience, reserved exclusively for hotel guests aged 18 and over. It opens at 8:00 am, which means during the first two hours of the day, before day visitors are admitted to the main property, you have access to this private area while the rest of the resort is still quiet.

There's a bar with a full food menu, lounge seating within the lush gardens, and a level of privacy and calm that's hard to find once the property gets busy. If you're a hotel guest, the Shangri-La access combined with that early-morning window is one of the clearest practical advantages of staying on-site.

The Thermal Pools

The main thermal complex covers 7,790 sq m (83,880 sq ft) of tropical garden and includes 23 distinct pools fed by the natural hot springs river flowing from Arenal Volcano. The water is never reheated or recycled - it flows continuously, carrying volcanic minerals from the source.

Temperatures across the pools range from 22°C to 38°C (72°F to 100°F), and the variation in depth, temperature, and surrounding vegetation means each pool has its own character. Some are open and social; others are quieter, tucked into dense foliage.

Hotel guests have unlimited access throughout their stay, including exclusive entry from 8:00 am to 10:00 am before day visitors arrive. If you visit during one of the region's warm tropical rains - common in the green season from May to November - the experience of cool rain meeting volcanic heat is one of those things that's difficult to explain in advance but easy to understand the moment it's happening.

Wooden bridges span the thermal river at various points throughout the complex, and the trails that connect the pools invite exploration rather than efficient movement from one place to the next. The bridges are particularly good vantage points for watching the river - the way the warm water moves through the garden, the steam that rises in the cooler early mornings, the light that filters through the canopy overhead.

The Surroundings

The surrounding region is one of the most biodiverse areas in Central America, and Arenal Volcano National Park sits directly adjacent to the resort. Within the park, you can walk lava trails that trace the flow from the 1968 eruption - still visibly volcanic, still raw in places - and pass a centuries-old ceiba tree that serves as a marker of how long this forest has been undisturbed.

Wildlife encounters along the trails are common: howler monkeys, toucans, coatis, and raccoons are regular presences in and around the park and the resort's own private reserve.

The resort's 230-hectare (570-acre) private rainforest reserve offers its own pathways, and the transition from the thermal gardens into the deeper forest is seamless. Beyond the park, Lake Arenal's shoreline provides hiking with expansive views of the water and the volcano reflected in it.

The broader La Fortuna area - with its waterfalls, river systems, and interconnected trail networks - means that however many days you spend here, there is almost always another trail worth following.
