About Our Project
Nature Observatorio is a beautiful treehouse suspended 25 meters up on a tree in the middle of the jungle in the Gandoca Manzanillo Wildlife Refuge at the Caribbean coast of Costa Rica.
Because you are true adventurer and nature lover. To view the jungle from high above the treeline is one of the most rewarding experiences, and certainly one of the top joys of life. You will hike in and out from the jungle and climb up and down from the Treehouse fully under our supervision. We promise you one of the most enriching experience of your life.
The Amazing Treehouse and Nature Observatorio is unparalleled project in human history. Suspended on nylon straps, the Observatorio is built in place, assembled like a 'Lego' project, high in the air, without ever harming the tree in any way. The entire structure weighs only 2.200kg. Upstairs are two comfortable bedrooms, and downstairs is your viewing platform. The 360 degree panoramic vista encompasses the surrounding greenery, as well as the Caribbean Ocean stretching out to the eastern horizon, and the blue tropical sky above.
Nature Observatorio is suspended on app. 350 years old monumental Nispero tree. The plan is to keep it on our 'Nispero' tree for up to ten years. Then it will be removed, refurbished and reassembled on a different tree.
Almost zero. Not a single nail or screw is used in the Treehouse emplacement. It may also be the first house-like structure to be built from the top down. It has two floors (the first about 25 mt. from the ground), of approximately 60 square meters. It is light, modern and removable. Our goal is always to keep everything as eco-friendly as is humanly possible. Rain water is supplying the Observatorio and its modern bathroom. Solar energy is providing electricity for all the usual home conveniences.
Nature Observatorio won "Best innovation" prize at the Responsible Tourism Awards 2012, organized by responsibletravel.com. More info can be found at https://www.natureobservatorio.com/award.html.
This project is mainly for adventurers and nature lovers. If you don't want to spend the night there you can just visit it for a day tour which takes app. 4.5 hours to complete. Either or, you are up for something very special. We will be delighted to welcome you in our Amazing Treehouse.
