Who are we?

The Bushmaster Conservation Project is a conservation program founded by the Herpetological Education & Research Project (H.E.R.P.).

It is an effort to protect and understand the Central-American Bushmaster (Lachesis stenophrys) in its natural habitat in the South Caribbean region of Costa Rica. The effort has been set in motion by five passionate naturalists, devoted to protect and study their favorite snake genus, the Bushmaster.

The project is housed in the Biological Research Station, located in the middle of the primary rainforests of the Kéköldi Indigenous Reserve.

The Research Station


The Research Station is situated in the heart of the primary rainforests engulfing the Kéköldi Indigenous Reserve. It is accessible from the main 256 road going to Playa Negra by a trail leading deep into the forest. Getting up to the station requires a 2km jungle hike through some challenging terrain, so make sure you come prepared!

The station itself has a kitchen, library, office, bathrooms, showers and a main area with hammocks and tables used for working, eating and relaxing. The main area has an immense balcony that looks down on the forest floor and into the forest canopy. Sloths, kinkajous, snakes and birds can be seen minding their own business, straight from the platform.

The station has a second floor with accommodations for up to 24 people, with
6 rooms, each equipped with two bunk beds. Bed linens and towels are provided. There is third floor on top, that can also be used for camping under the open skies or bird watching.

Around the project you can hike several long jungle trails that amount up to around 10km! These hikes will bring you to small creek habitats, hilly slopes, dense rainforests, large rivers, beautiful sceneries and even a 50m high waterfall.
