The Space

Please message us if we will be your first or last destination in Costa Rica. We highly recommend booking on weekdays for more privacy and tranquility, as we have more day visitors from 9 am to 6 pm to our hot springs on the weekends, especially Sundays. If your reservation includes a Sunday, we highly recommend planning a day outing to the many wonderful nearby activities.

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. The pools are cleaned every morning starting at 6 am, but one hot spring will always be available. Many factors may dictate scheduling, including weather. We do not charge for children 17 and under -- but we will not accept reservations for the Tree House for families with children under 5 years old for whom a 20 foot fall from the balcony would be very serious.

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). The small and large cool springs pools both have water slides, and there is a small water slide in one of the shallow and moderate temperature pools for small children.

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.

Other Activities on our 35 acre rainforest reserve:
• Bird-watching: many types of toucans, oropendulas, parrots, hummingbirds, and the rare green macaw
• Rainforest: enjoy it from the casita porch or hot springs pools, take easy walks on paths or more adventurous hikes
• Fossils – enjoy our collection or hunt (gently) for your own
• Wildlife: two-toed sloths, iguanas, capuchin and mantled howler monkeys, tree frogs, birds, butterflies, and many others.

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 a 1.5 hour drive to La Paz Waterfall Gardens and Volcano (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.

Guest Access

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(with water slides) 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. The pools are cleaned daily from 6 am to 9 am but one pool is always available -- there are many factors involved, including weather, that may dictate when the pools are ready.

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.
