Thermal River

Rio Perdido, which means “lost river”, is the centerpiece of the 600-acre private reserve. This mile long thermo-mineral gorge has dozens of hot pools wich draw their energy from deep magma flows, and is a completely natural and inspiring setting, unlike any other place on the planet.

Along the riverbed, there are 8 registered springs, which emanate over 4000 gallons of hot water every minute.  At these points, the water is a bit too hot for more than a dip of the foot, but as a result of the spring water mixing into the river’s flow, there are dozens of soothing pools of varying temperatures, which are absolutely perfect for prolonged bathing; and just upstream from the spring, you can actually swim in cool water.

Rio Perdido's Medicinal Water Spring

This spring was historically used by residents of Cañas, the county that is located directly south of Bagaces. It appears that they had been using the water for its curative properties for many generations and it is probable that they had picked this up from the Cabecar natives that had once thrived in the area (we have found many ancient artifacts scattered around these springs and CR’s museum authorities have dated them to at least 400 years ago). So, we know that these medicinal waters were used as a complement to bathing in the thermal springs, located in the canyon below.

Our consistent and comprehensive testing of the water's properties has revealed a rich and unique mineral balance that supports the historical claims of its health benefits. While there are many unproven theories derived from the physical composition of these waters, both, prominent scientists of international origins, as well as habitual drinkers, insist that this water can lower cholesterol and LDL levels. Consequently, this results in improved blood circulation and cardiovascular health, in general.

The water from the Medicinal Spring has a very distinctive taste, due to the presence of sodium ions (approx 1g/L), bicarbonates (over 2g/L), magnesium (7 mg/L), potassium (51mg/L), calcium (32 mg/L), chlorides (500 mg/L), Sulfates (47 mg/L), a high concentration of Silica (77 mg/L), and other essential salts and minerals. Nitrate levels were insignificant / nil. It is a naturally sparkling, volcanic mineral water.

The springs originate at a depth of 200-300ft where the spring water acquires most of its mineral-salts composition, as well as several beneficial biological elements. As the water ascends, thanks to natural, geological pressurization, the flow passes through various layers of rock and mineral-deposits which fortify and purify the water. The Medicinal Spring sources at 75 to 82 degrees Fahrenheit.

Aside from the scientific data, locals assure that the water also helps reduce stress levels and significantly wanes most abdominal aches. The townsfolk add that drinking two or three glasses of mineral water prior to breakfast and complementing this with a good walk, will help soothe practically any ailment.
The unique "wellness trifecta”, consisting of drinking this medicinally potent water, soaking in the canyon's therapeutic hot springs, and applying the chemically active volcanic mud offers us a one-of-a-kind procedure that is 100% natural and highly effective.
