  • Rio Perdido Hotel & Thermal River Activites:
  • Hotel Rio Perdido Mountain Bike Park

  • Eco-adventure lovers will be absolutely delighted with the activities in and around Rio Perdido. There is so much to do in this gloriously undiscovered area – from exhilarating zip-line tours through the canyon to thrill-inducing mountain bike rides and scenic white water tubing excursions and picturesque hikes to soothing hot springs.

    Should you wish to venture slightly further afield, our hotel is just a short drive from attractions including the majestic Miravalles Volcano and the Llanos del Cortés Waterfalls.

  • Thermal River
    Rio Perdido, which means “lost river”, is the centerpiece of the 600-acre private reserve. This 45-meter, thermo-mineral gorge draws 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, from which over 4000 gallons of hot water emanate 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 with 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.

  • Zipline Tours
    While there are hundreds of zip-line tours throughout the country, our Canyon Adventure is truly innovative. Under the guidance of renowned adventure designers, we have created a sequence that will please and surprise. Our inspiring Rio Blanco canyon is the main stage for the awesome cable-based adventure.

  • Scenic Hiking Points

    Yurro Waterfall - This short hike is approximately 1 kilometer out and back. It is a relatively flat, yet attractive trail that takes you across the main hanging bridge. The destination is the top of a waterfall. Note that the Yurro's slate base may be dry from January to May, but it is always beautiful. Please do not walk on the rocks, as there are steep and slippery sections.

    The Medicinal Spring - This hike is 2.5 kilometers out and back. It’s a relatively flat trail that takes you beyond the Yurro Waterfall, through the Miravalles dry forest and then to a denser and taller forest where the spring and streams are located. Old-time residents of the Montano and Santa Fe areas consider this water to have healing properties. It actually tastes a bit like Alka-Seltzer – which, according to our lab testing, is due to the high concentrations of diluted magnesium.

    Mesa Norte - Panoramic Lookout - The total distance of this hike is 3.5 kilometers out and back. The walk begins with a soft ascent through the woods, leading to an uncovered trail and then to a steeper climb for the last 250 meters before arriving at a small, flat mesa.

    From the top, you can see all of the Guanacaste volcanoes, including the Miravalles, the Rincon de la Vieja and the Tenorio. Because of the complete absence of artificial illumination, this is an amazing place to stargaze, to see the lit domes that mark the distant urban centers and to appreciate 360 degrees of undisturbed nature under the moonlight.

    Las Tumbas - Panoramic Lookout - The shorter version of this walk is 5 kilometers out and back, with the option of an 8-10 kilometer loop for those desiring a more challenging hike.

    The views are comparable if not more impressive than those you can appreciate from Mesa Norte. The eroded volcanic rock formations in this area are amazing. We strongly recommend that you request one of our well-trained guides and plan accordingly so as to not be caught in the dark.

  • The Bike Park At Rio Perdido
    Our permanently evolving MTB circuit attracts riders from far and wide; it offers solid rock segments, sand, raw earth, bridges, ramps, banks and even a few downhills in the advanced circuit. Of course, the circuit’s more advanced segments can be foregone by amateur riders or those who simply want a less challenging ride without the rocky climbs and heart-stopping plunges.

    Riders can opt for different routes, ranging in distance from 8 kilometers to over 20 kilometers, without having to repeat single-track segments. While many MTB fanatics would not consider this to be "long distance," most riders are content to finish the circuit and then opt for a rest in the hot springs.

    For those not running a time-trial, the route offers amazing stops that include short treks to several panoramic lookouts, two waterfalls, a cave, the remains of a home that dates back to Costa Rica’s colonial period and a naturally carbonated water spring historically lauded for its medicinal qualities.

    Unlike most activities at Rio Perdido, the Bike Park is designed for a focused rider and is not recommended for beginners. Those visiting the BPRP for the first time may want to consider riding with one of our guides.

  • White Water Tubing At Rio Perdido
    White water tubing at Rio Perdido is awesome. We use modern equipment to help you safely traverse the river and get a real sense of the canyon and its magic.

    There are parts of the canyon where the rock walls narrow and daylight is scarce. Echoes grow louder and if you remain quiet for a bit, you will find that you are not alone; birds, monkeys and, occasionally, some larger mammals will announce their presence. Look for the hot water spouts along the eastern rock walls.

    Please take note that this activity is not suitable for everyone. While a slow float will take you through most of the trajectory, there are several intense rapids along the way.

    There is always a chance of making contact with some of the exposed rocks, which can result in bruising and even minor cuts. This is more likely to occur in the dry season, when the current slows and the water level drops, as more rocks become exposed.
