The Colibri Casita Is a charming new cottage at our 35 acre Bio Thermales rainforest reserve with natural hot and cool springs pools in the north-central Costa Rican heartland. This is authentic Costa Rica: clean, comfortable and close to nature.
We are three hours north of San Jose (airport), 45 minutes east of Fortuna and Volcano Arenal.
Our hot springs are ancient “deep Earth” sources that bubble up through the rainforest floor, bringing mineral-rich waters that have been in the Earth for at least 10,000 years. Our waters are rich in bicarbonates, calcium and magnesium, low in sulfur, and slightly acidic, qualities shared by many of the world's best hot springs.
Guests enjoy 24 hour access to the hot springs, swimming pools and rainforest trails.
Please note that we do not charge extra for children under 18 years old.

Food/Meals: The casita has a kitchen. There are many restaurants and a good supermarket within a 15 minute drive. Traditional Costa Rican meals can be delivered from a local caterer for very reasonable prices (Costa Rican food is tasty but not spicy). Otherwise, we can call a taxi or synchronize a food shopping trip when we go to town for errands.
Driving from SJO airport:
We highly recommend at least a small 4 wheel drive car. The last 3 kilometers are country roads.
Three hours of daylight are needed to safely drive here from the SJO airport before sunset at 5:30 pm. The drive through mountainous cloud forests is splendid in daylight, but prone to fog and rain, especially at night, creating hazardous visibility conditions after dark. Finding our countryside location will also be far easier if you arrive the first time before sunset. If your plane lands in the morning or mid-day, you can drive here directly from the airport. Otherwise, it is safer to book a room near the airport on your first night or we can help you arrange a private professional driver.
Last night in Costa Rica:
To drive directly to the SJO airport on the same day as your departing flight, you will need an afternoon or evening departing flight. For early morning departing flights, it is necessary to stay your last night near the airport.
Please email us before booking if we are your first and/or last destination in Costa Rica.
Five of our 9 organic form hot springs pools of various temperatures are located in the rainforest, and 4 hot springs pools as well as 2 cool natural spring swimming pools, are located in a meadow, surrounded by rainforest. Casita guests enjoy 24 hour hot springs pools and 35 acres of rainforest access at no charge.
Interaction with Guests
We enjoy interacting with our guests and making suggestions for and even help book activities in the area, as well as options for transportation. For personal interaction, we take our cues from our guests -- if they prefer privacy, we respect that; if they enjoy interaction, we are open to interaction and have met many delightful new friends in this way. If we are away, our Costa Rican manager, Johan, moves into our house with his lovely wife and baby daughter, so there is always a manager onsite.
We are off the beaten tourist track, in a rural community of rainforest, dairy farms and orchards, yet only a 45 minute drive to We are a 45 minute drive from the many activities in Fortuna and Volcano Arenal -- such as ziplines, hanging bridges, white water rafting, slow river floats or kayaking through wildlife sanctuaries -- or an hour drive from the less trodden cloud forest of Juan Castro Blanco National Park, with wonderful bird watching, including the Resplendent Quetzal. To see Quetzals, the best season is Feb to early May.
No smoking inside the casita or in the pools. No glass bottles or dishes at the pools. Children must be supervised at all times in the pools or rainforest, and parents must prevent children from diving or jumping into the pools to avoid injury. Parents must assume responsibility for their children. Guests must be willing to open/shut the gate if they leave the property after 6pm.
We were thrilled when Kathy & Bernie could accommodate us for a second night (see our review below for more details). We highly recommend a stay at BioThermales.
Bio Thermales is truly a special and beautiful place. The Colibri Casita was clean, well equipped, and comfortable. Our gracious hosts, Kathy and Bernie, were friendly and helpful. We enjoyed soaking and swimming in the hot springs and the close proximity to nature made our stay memorable. We will definitely return!
We chose to stay at Biothermales because it was highly recommended by a friend and we were so pleased that instead of staying for 1 night we stayed for two. My parents were visiting from Canada and the hot springs were exactly what the doctor ordered to thaw from the deep freeze of the cold winter in Newfoundland and Labrador. Kathy and Bernie were both very accommodating. We will definitely be going back when we have to make our next exit from the country!
This is one of the best place we went in Costa Rica. We really enjoyed the hot springs and had so much fun.
Kathy and Bernie are a great hosts. Very helpful and caring.
We had great time there!
Wow! What a beautiful place! In the heart of a jungle you can relax in a natural mineral hot spring. Kathy and Bernie are extremely friendly and helpful. Kathy is super thorough and made our trip easier with her suggestions. And they've got a really awesome story too! We loved hanging out here and would definitely come back!
Kathy & Bernie were most gracious hosts.
We were greeted at the top of the VERY steep and adventurous driveway with smiles. Bernie showed us to our casita, showed us around the house, then took us for a walk around the grounds showing us the different pools. We opted not to pre-order food, so Bernie pulled out a map and gave a few suggestions, from expensive steak to local restaurants.
Once the public leaves at night the pools are so very quiet and calming. No one came up to bother us while we sat in the warm and hot pools into the wee hours of the night.
Having rolled in around sunset we didn't get a chance to see the full beauty of the views from the room until the morning. WOW! A balcony connected to the room looks out over the cold pool, a field and tree tops. Pure Costa Rican beauty.
Kathy and Bernie were attentive and very patently. They look out for everyone staying at their casitas; but they give you plenty of space to sit and soak up the serenity.
Highly recommended. Take a few days and it will recharge you. Make sure to sit in the hot pools during the midnight downpours!
Wonderful experience! A group of five of us had the privilege of staying in Colibri at Bio Thermales. While a bit off the beaten path and not located close to restaurants or shops, we enjoyed the serenity and natural surroundings of this location. We loved the different temperatures of the various thermal pools and the unlimited access to the pools. But the absolute best part of this was the personal help from Kathy. She went above and beyond in helping us organize our trip and connected us with Frank who served as our driver and tour guide for three days. Kathy is fabulous at communicating and we were VERY lucky to be introduced to Frank. Thank you thank you thank you! The only downsides, which were minor, is that the wifi is only available at the main house and that we only got one towel per person.
