Rainforest Casita3 with Hot Springs

Cabin - Entire home/apt · Aguas Zarcas, Alajuela, Costa Rica

The Space

The Colibri (Hummingbird) Casita is one of three charming new cottages and a Tree House on the grounds of the 35 acre Bio Thermales rainforest reserve 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.

Please message us before booking if we are your first and/or last destination in Costa Rica if you plan to drive directly from the airport to us.

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 non-volcanic and slightly acidic waters are rich in calcium and magnesium, low in sulfur.

Four of our 9 organic form hot springs pools are located in the rainforest, and 5 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). Casita guests enjoy 24 hour hot springs access at no charge.

Note on wifi – wifi is highly variable in speed and availability in our locale (it’s a jungle out there!). We are currently working on a system to improve our wifi system. If internet access is very important to your work, the best option is to bring a laptop/device with a USB port and purchase a 3G stick at SJO airport for about $50, no contract required. Remote locations in Costa Rica usually have spotty or no wifi and reception is weather dependent.

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, colorful tree frogs, birds, butterflies

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 from the less trodden cloud forest of Juan Castro Blanco National Park, with wonderful bird watching, including the Resplendent Quetzal.

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 have the opportunity to experience warm and friendly Tico culture. Bio Thermales is generally not crowded, however, except on Sundays and major holidays.

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:

In general, a small 4x4 car is good for most locations in Costa Rica.

Please email us before booking if we are your first and/or last destination in Costa Rica.

Three hours of daylight are needed to safely drive here from the SJO airport before sunset at 5:30 pm. All roads from SJO pass through mountainous cloud forests that are prone to fog and rain 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 hire a private driver and rent a car locally.

Last night in Costa Rica:
Staying near the airport on the night before a departing flight is prudent – in case traffic, road or weather conditions cause unexpected delays -- unless you have an afternoon or evening departing flight.

Guest Access

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 and one cool fresh spring pool in the rainforest (see below for more information).

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.

Overall Guest Satisfaction

Check In
  • Excellent stay at the Rainforest Casita. Location & surrounding's are beautiful and peaceful (a lot of birds to see just from the balcony!) The casita is comfortable with character and excellent amenities, kitchen, large, modern bathroom, AC in bedroom and large balcony.
    Owners were not present when we stayed but the manager was very helpful, friendly & professional. Communication to help before and during the stay was excellent & full of useful details.
    An excellent place to stay either to relax or as a base to explore the North at a very reasonable price for the quality of the offering.

  • I give a five star rating regarding my experience. I was quite ill with a toothache following some dental surgery. Kathy went out of her way to take care of me. The soak in the hot springs water on the property was wonderful. I wouldn't have asked for a more kind and caring person. The property is beautiful!
    Muchas gracias!

  • It is safe to say that Kathy made our entire Costa Rican vacation a dream vacation - even the days that we were not at Bio Thermale Hot springs were planned with her help :). She guided us on where to go and where to stay and every one of her recommendations was perfect. Talk about a gracious host?

    As to Bio Thermales Hot spring, the Casitas are quaint, exotic, comfortable, handmade (by Bernie!) marvels, and the hot springs are just sublime gifts of nature, perfectly cultivated by Bio Thermales. It is a little bit away from the action at la Fortuna which for us was a good thing, We even bought fresh eggs (from their own hens) , tilapia (from their fish farm), and fresh milk from an adjacent milk farm. Plus Kathy and Bernie's lovable dog Peppy was a big hit with the kids.

    Needless to say, we will do everything possible to come back.

Pura Vida! (“Pure life” is an all-purpose greeting in Costa Rica, as well as a way of life.) Kathy and Bernie (American and German, respectively) have designed Bio Thermales so guests may enjoy the beneficent hot springs and rainforest while making only positive impacts on the rainforest in our care. This is a very healing and lovely place and we look forward to sharing it with you. We have worked on many environmental endeavors, professionally and as volunteers. Bernie is an engineer, organic gardener, woodworker, artist and great cook. Kathy is a nutritionist, writer, graphic designer, and community organizer. We have also been active in many human rights efforts. We have a black Lab, horses, cows, tilapia pond and free-ranging chickens.
