About This Listing
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 couldn't be happier with the welcome atmosphere Kathy & Bernie provided!
We were there for 7 days. Two adults, two kids (11 and 10). The casita (separate villa/house). Two separate (website hidden) worked great in both rooms (which helped a LOT)! The rest of the house is not meant to be air-conditioned. The kitchen has all the basic utensils, cookware, etc that you will need. It has a full range of equipment (fridge, stove, oven, microwave, coffee maker).
We all LOVED the hot springs. The kids also loved the spring-water pools/slides.
Kathy was MORE than help with pre-information (maps, tips, recommendations), tips on local activities, and anything we needed while there. It almost felt like we were staying with relatives.
There are PLENTY of pools on-site. Many hot/warm/cool spring pools. Some large, some small. There are 2 sprint-water pools. They are currently building a rather large slide into the big spring pool (which will be great for kids).
Sundays can get quite busy with many local tico families visiting the springs. But it didn't stop or slow us down at all. Plenty of area to cook or barbecue (with coal/wood). Plenty of seating, benches, and picnic tables on the grounds.
The grounds/area is great. Although the small dirt/rock road is similar to many remote Costa Rican roads. It's not "off road", but it's definitely slow-going with many pot-holes and rocks. We made it with NO PROBLEMS in a small 2-wheel drive hatchback car with low-clearance. If anything, this is the only drawback of Bio Thermales. In this small car, it takes 15-20 minutes just to reach the main road. Even driving in the dark (which Kathy/Bernie did not recommend) and while raining, the roads were not muddy or treacherous (even for a 2-wheel drive low-clearance car).
Onsite Wifi is still intermittent/slow, but that's due to the local internet provider & remoteness of the location... but they were working on a better solution in the near future.
I would definitely like to visit again, but we probably wouldn't stay 7 days. 4-5 days would have been better for us, but we'll definitely want to go back.
My only regret is we didn't get a chance to go through the nature hike/trails that are on the property.
Staying with Kathy and Bernie was such a sweet experience. They do really what they can to make you comfortable and welcome. Their rainforest casita was super comfortable, clean and nicely decorated. We loved it there and the hotspring pools are just an other plus!
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!
