The Mariposa 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.
The Mariposa Casita is one of three charming new cottages on the grounds of our 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. Mariposa Casita is wheelchair accessible.
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 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). Casita guests enjoy 24 hour hot springs pools and 35 acres of rainforest access at no charge.

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 (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 have the opportunity to experience warm and friendly Tico (website hidden) Thermales is generally not crowded, however, except on 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:
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 at night, creating hazardous visibility conditions. 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.
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.
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 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). 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.
No smoking inside the casita. 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. Guests must be willing to open/shut the gate if they leave the property after 6pm.
Bernie and Kathy are both just lovely people!
The lay out, the architecture, the art work, the design of the Biothermals, it's all fabulous!
They keep adding and improving the property with such things as more tree houses and slides for the hot tubs.
I stayed here a couple weekdays and it was pretty exclusive to us few tourist dwellers.
The wifi was decent. The hot springs were phenomenal! Seriously they felt sooo good.
The trail into their rain forest was pretty cool. I saw some real interesting wild life. Got to have courage for it though. I saw 4 Tolomuco's and they threw me a few growls. I thought I would have to fight them with my walking stick, but they stayed away from me. I was ready though.
Boots are a must for this walking trail and it does involve climbing and such.
Overall, I highly HIGHLY recommend staying here a couple days.
We had a wonderfull stay at Kathy and Bernies place - we enjoyed the hospitality and the surroundings (both indoor and outdoor) very very much. Kathy was very friendly, knowledgeable and supportive. We had only one night, but we could easily have spend more days in this lovely place.
Very nice place to stay. The hosts were helpful and very kind! Lots to do and see in the area and very relaxing place to come back to. A bit off the beaten path and thats why we chose it, so it was a wonderful stay. Highly recommend going to the national parks and doing your own exploring, beautiful by the volcano!
The cabin that we stayed in was beautiful, clean, spacious, and comfortable. The hosts, Kathy and Bernie were incredibly sweet and helpful to me and my girlfriend. They give you tons of advice about everything you might wonder about (food, attractions, suggested travel routes), but maybe you didn't think about prior to your arrival. Their advice on how to get there was not heeded by us as we let our GPS guide us; that was a big mistake on our part. The road we took was dangerous and curvy. The route we took to leave, their suggested route for our arrival as well, was much safer and less stomach-churning. The bio thermals themselves are wonderful. It was such a relaxing end to our days out and about in the area to come back and sit in the well-built and clean natural hot springs. They employ a number of local Ticos and it felt nice to support this type of business. We happened to go during the end of the rainy season so the hiking trails were not in the greatest condition but they certainly felt like an adventure. The location was great for us. We made a couple of day trips to Volcan Poas, Volcan Arenal, and the Arenal Hanging Bridges. Our biggest regret about choosing Bio Thermales is that we didn't stay in the treehouse. It was gorgeous.
It was the second time I was at the hot springs but the first time in the cabins. It was absolutely great, especially after the day visitors leave and you have the springs for yourself. The cabin was well equipped and it was great cooking our own meal after a day soaking in the pools. It was my daughters birthday and I took her and three friends aged between 13 and 16 with me, they thoroughly enjoyed it.
I loved so many things about this Place. Kathy and Bernie were wonderful. She is such an interesting person. The springs are wonderful for relaxing after a long day of exploring. The rooms are awesome. my only regret was that I wasn"t able to stay longer and check out all the beauty of their own private rainforest.
Kathy and Bernie are very friendly and we enjoyed our stay in the casita. The casita is comfortable and clean. Kathy explained and showed us everything and we got a delicious dinner and breakfast as well. So our stay was perfect, unfortunately to short.
