The water flows warm between the rocks covered in moss, reaching temperatures that can exceed 40 degrees Celsius. This is not an artificial facility, but rather natural hot springs fed by the geothermal heat of the Arenal Volcano, one of the most active volcanoes in Central America, which rises about 1,670 meters above sea level in the province of Alajuela. The Tabacón Grand Spa Thermal Resort is located at the foot of this mountain, immersed in a rainforest that is part of the Arenal biological corridor.
The resort is situated along National Route 142, just a few kilometers from the center of La Fortuna, the main populated area of the region. The Tabacón hot springs are not just simple heated pools: the thermal water flows along channels and natural waterfalls that traverse the tropical vegetation, creating a system of pools with varying temperatures, some cooler for relaxation, others warmer for therapeutic benefits. Along the paths, one can observe heliconias, bromeliads, and wild orchids, while the local fauna — toucans, hummingbirds, and colorful frogs — moves among the vegetation.
The thermal water system
The Tabacón springs are fed by the hydrothermal activity of the Arenal Volcano, which naturally heats the underground waters before they emerge to the surface. The complex includes several levels of pools and baths connected by an artificially channeled thermal river but fed by geologically natural water. The temperatures vary depending on the point: in the pools closest to the source, the water is warmer, while descending along the path, it progressively cools down.
The internal Grand Spa offers treatments that integrate local ingredients such as Costa Rican cocoa and volcanic mud, considered rich in minerals. The available treatments include massages with tropical oils and body scrubs. The outdoor thermal experience, however, remains the focal point of the visit: the sound of water flowing between the rocks and the view of the rainforest extending towards the volcano create a setting that is hard to replicate in artificial facilities.
What to Observe in the Natural Landscape
Walking along the resort's trails, visitors can notice how the vegetation changes near the hottest springs: some species of plants adapted to humidity and heat grow particularly lush. The artificially constructed thermal waterfalls within the complex channel the hot water in a scenic way, but the source remains genuinely volcanic. In the evening, when the rainforest mist descends, the atmosphere becomes particularly evocative.
The Arenal Volcano, visible from most areas of the resort on clear days, was in continuous eruption from 1968 to 2010. It is currently in a phase of lower activity but remains classified as an active volcano. Its conical and symmetrical silhouette dominates the landscape and serves as the constant backdrop for the thermal experience. In the early hours of the morning, before the clouds envelop the cone, the view is particularly clear.
Therapeutic Experience and Wellness
The volcanic thermal waters contain minerals such as calcium, magnesium, and silica, which according to local tradition have beneficial properties for the skin and muscles. Prolonged immersion in warm waters promotes muscle relaxation and improves peripheral circulation, effects also recognized by conventional medicine. The thermal path at Tabacón is structured to allow stops in pools at different temperatures, alternating intense heat with cooler areas.
The resort's restaurant, Restaurante Altamira, serves Costa Rican and international cuisine with local ingredients. Some guests choose to dine after the thermal session, when the body is still relaxed from the warm water. The service also includes a bar with direct access to the thermal areas, allowing guests to sip refreshing drinks without leaving the pools.
Practical tips for the visit
The daily entrance to the Tabacón hot springs for external visitors (non-hotel guests) has an indicative cost that ranges around 80-100 US dollars per adult, an amount that includes access to all the hot springs and the buffet restaurant. It is strongly recommended to book in advance, especially during the high season months from December to April, when attendance is higher. The resort accepts a limited number of daily visitors to maintain a quality level of experience.
The ideal time for the visit is late afternoon, starting around 4:00 PM, when sunlight filters obliquely through the forest and external temperatures drop, making the contrast with the warm water more pleasant. Wearing water shoes or footwear with non-slip soles is practical for moving between the wet rocks. The road from La Fortuna is paved and accessible with any vehicle; taxi transfers or local shuttle services are available from the city center.
