About This Listing
The Tree House Is charming, new and handcrafted 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, and the many activities there and nearby.
Guests enjoy 24/day access to our hot springs and trails in our 35 acre rainforest at no extra charge. We do not charge for children 17 and under -- but the Tree House is not appropriate for children under 5 years, for whom a 20 foot fall from the balcony would be very dangerous.
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.
Five of our 9 organic form hot springs pools are located in the rainforest, and 4 hot springs pools as well as a small and 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 that surround the Tree House 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 (website hidden) 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 (website hidden) 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 ask us to book a private driver ($145) 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 stay near the airport on the night before.
Five of our 9 organic form hot springs pools are located in the rainforest, and 4 hot springs pools as well as a small and a large cool spring swimming pool are located in a meadow, surrounded by rainforest and one cool fresh spring pool in the rainforest (see below for more information). Tree House 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.
No smoking or flame inside the wooden Tree House or on the wooden deck. Barbecue grill is provided below the Tree House on ground level but may not be used on the deck. No glass bottles or dishes may be used in the pools. Guests leaving the property after 6 pm must be willing to close the gate behind them.
Children must be supervised at all times in the pools and rainforest.
What else can we say to describe our (email hidden) Thermales treehouse other than, PERFECTION! We were initially greeted by Kathy, Bernie & pepe (their loving dog) with open arms and shown around the property which was even more relaxing and beautiful than we were even expecting. The hot springs were so immaculately kept, artistically crafted, and were the perfect way to relax and enjoy the surrounding sounds of nature.
Our treehouse was also a unique and enjoyable experience...after all, it's not everyday you're in a treehouse, in the middle of the rainforest! The space was clean, and had everything we needed to enjoy our stay. We even took advantage of having home cooked meals delivered to the house which were very delicious and quite affordable.
Our stay was so 'perfect' we even got engaged here! Kathy, Bernie, and staff made our stay extra special and we could not say enough about how much we enjoyed Bio Thermales!
Kathy and Bernie were wonderful! Kathy was so helpful with questions I had while still in America, and once we were in Costa Rica. The tree house is gorgeous as well as the grounds. Also the mineral pools were better than we expected. If you can get a reservation don't miss it!
Our experience with Kathy and Bernie was everything we hoped for and more. They've done a fantastic job creating a unique and special experience for their guests. The treehouse itself was both beautiful and comfortable, with amazing views from up in the trees. It was obvious they both genuinely cared for our experience, and even offered up fresh produce from their garden to go with the dinner we planned on cooking for ourselves in the tree house. The hot springs and pools were unique and a pleasure to enjoy. The property also offers a 15 and 45 minute hikes through rainforest that was enjoyable with lots of wildlife waiting to be discovered. We stayed only one night but cannot wait to return next time we are in Costa Rica.
Beautiful place, just like described! Kathy and Bernie were very welcoming, helpful and had very good tips for the rest of our trip. Really nice pools and a beautiful trail in the jungle that everyone should try.
We arrived during dark and we don't suggest arriving after 6, since it was harder to find this way. It was easy to cook ourselves food in the kitchen and it was very cosy to sleep in. We highly suggest this sureal experience!
We stayed at Bio Termales for 4 nights and had great time. Both Treehouse and all cottages are fully furnished and spotless clean. The hot springs are very relaxing and there are many tourist attractions nearby - you won't get bored at all. Resort grounds were well kept and both Kathy and Bernie are fantastic hosts who made us really felt like at home. Kathy is great communicator, she sent us all directions beforehand and after our arrival explained everything about the resort and its surroundings. My secret tip is to get some Tilapias from Bernie and cook them for dinner. They were fabulous! Thank you once again, hope to be back soon!
