The Tree House, as well as two charming new cottages, is on the grounds of the 35 acre Bio Thermales private rainforest with natural hot springs in the north-central Costa Rican heartland of rural farms and orchards near Aguas Zarcas and San Carlos (Quesada). This is authentic Costa Rica: clean, comfortable and close to nature. Three hours north of San Jose (airport), 45 minutes east of Fortuna and Volcano Arenal.
Guests enjoy 24/day access to our hot springs at no extra charge. We do not charge for children 17 and under.
Our hot springs are ancient “deep Earth” sources that bubble up through the rainforest floor, laden with 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. Four of our 8 organic form hot springs pools are located in the rainforest, and 4 hot springs pools as well as a large cool spring swimming pool are located in a meadow, surrounded by rainforest (see below for more information).
Parents of young children should evaluate whether the height of the Tree House is safe and appropriate for their children.There are railings around the balcony and stairs but a determined child could climb over them and fall or a very small child could crawl through the spaces in the railing. Every child is individual and their parents must use their best judgment and assume any risk.
The Tree House is built to strict Costa Rican building codes, but as with all tree houses, there is some movement when the wind blows, and this could be uncomfortable for people very sensitive to motion sickness.

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 20 minutes from the less trodden cloud forest of Juan Castro Blanco National Park.
Bio Thermales Hot Springs is open to the public for day use of the hot springs, and most of our day visitors are Costa Ricans, so you may also meet new Tico friends. Bio Thermales is generally not crowded, however, except on major holidays and Sundays.
Food/Meals: The Tree House 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, for those without cars, we can call a taxi or synchronize a food shopping trip when we go to town for errands.
Driving from SJO airport: Please message us before booking if we are your first and/or last destination in Costa Rica.
We 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 to noon, you can drive here directly from the airport. Otherwise, it is safer to book a room near the airport on your first night, or book a private driver ($130) and have a rental car delivered at no extra charge.
Last night in Costa Rica:
Driving directly to the SJO airport on the same day is possible if you book a flight in the afternoon. Please be aware that you must be at the airport 2.5 hours before departure. If you have an early morning departing flight it is basically necessary to stayi near the airport on the night before.

Two days like a dream !
The nest into the trees is perfect to stay in phase with the nature !
Kathy and Bernie had been perfect hosts !
Thank you again.
We had the great pleasure and the real treat of spending 3 nights at Bio Thermales last week. Our hosts Kathy and Bernie were wonderful, immensely knowledgeable and responsive to all of our needs.They have built a truly marvelous and unique property situated conveniently between Muelles and Aguas Zarcas, an hour from the chaos of La Fortuna and Arenal.The Cabinas are comfy and fully equipped with all the kitchen wares and appliances you'd need (be sure to bring all your food and supplies). We stayed in the treehouse - 31 steps up to the most amazing views of the property out front and the jungle out back from the 360 degree balcony. It is capped by a loft wrapped in the most amazing windows I've ever seen! The centerpiece of the place of course are the stone crafted natural hot springs and pools which beckon you all day and all night long. Springing right out of the mountains behind the Cabinas, the mineral waters are just perfect with a range of temperatures to satisfy anyone's preference. We are definitely going to stay there again!
The Treehouse, the hot spring pool in the rainforest are really great. In the morning i saw 8 monkeys "working" in the big tree, while i was relaxing in the hot nature pool. Its an extraordinary place, but dont go there on weekends. Biothermales is also a popular place for Tico families and its very crowded (more than 200 people around the threehouse having a barbecue and spending a good time there).
From Monday to Friday its a wonderful quiet place.
We stayed at the tree house. Had a great experience there. Kathy and Bernie address incredible hosts. Kathy went the extra mile, and then some. She helped me arrange most of my itinerary while at Costa Rica. She even called me before traveling to give me some tips on my stay.
My advice to travelers, which Kathy also gives, is try to come on weekdays. More availability to hot springs that way.
Thanks, will come back again if I'm in the area!
Kathy and Bernie were such wonderful hosts and were so helpful and welcoming. The treehouse is absolutely beautiful - definitely our favourite place that we stayed during our 6 weeks in Costa Rica. The creativity that has gone into designing the place is truly incredible, Bernie and Johan are really talented guys! My boyfriend and I stayed here for a week and there is so much to do in the surrounding area I would recommend at least a week minimum. Not only are there the great hot springs on site (which we used every day), but you are close enough to loads of other interesting places. Even though Arenal and Fortuna are close by, we would also thoroughly recommended some of the less explored attractions too. One amazing place we visited was the cloud forest of Juan Castro Blanco National Park - totally off the beaten track and wild, but beyond beautiful! It looks like something out of a fairy tale or off The Lord of the Rings. Volcan Poas is also definitely worth a visit, but make sure you go on a clear day and very early in the morning to get the best views. In terms of places that are close by, there is a river just down the road which has an excellent swimming hole and beautiful bright blue clear water. Definitely bring a car as getting around would be tricky without one, and make sure you have a meal at a Soda while you are in the area (there's one on the way to the Rio Celeste that is incredible!).
We had such a good time exploring the area, and I would definitely recommend staying at the treehouse. You will not find a more welcoming, friendly place than staying with Kathy and Bernie.
Kathy and Bernie were the ultimate hosts. Kathy and I exchanged a number of emails before even leaving the U.S. in which she helped me navigate our trip planning. Her directions were wonderfully helpful and much needed. Upon arrival she gave us a thorough tour of the facilities and layout of the land, allowed us to exchange money and arranged for the first couple of meals to be provided by neighbors. We couldn't have asked for a more magical experience staying in the treehouse, going to sleep with sounds of a gurgling river , birds, insects, etc. in the background. The hotsprings pools were exquisite....hot, private, clean, accessible and masterfully engineered. Thanks folks for the great experience! Annie & Eric
We enjoyed three exciting days of fun living in the tree house and soaking in the thermal hot springs. Bernie and Kathy have done a great job of turning the area into an wonderful place to relax and literally taking relaxation to a new level.
Anne and I drove to La Fortunate, hiked to the falls, went to a butterfly conservatory and had some great meals while living in the tree house. Thanks much for the hospitality and adventure as we experience the many beauties that CR offers!
Kathy and Bernie were great hosts and we really enjoyed our stay.
We stayed at the treehouse for one night and wish we could have extended our stay. The outdoor thermales were so relaxing. It was a great way to start the morning. Kathy and Bernie were gracious hosts. I will certainly recommend a visit to Bio Thermales to friends who visit Costa Rica in the future!
We had an amazing time at Biothermales. What a place! We stayed in the treehouse and really enjoyed it. The baths were fantastic. Kathy took a lot of time to orient us to the place and the area. Thanks for everything and we will see you next time.
