We are…Tourism Financing Biodiversity Conservation

Sustainable Development ● Habitat Reforestation ● Environmental Education

The Titi Conservation Alliance works to protect the endangered Titi (squirrel) Monkey through efforts focused on the Conservation of the area surrounding Manuel Antonio National Park.

To accomplish this, we work as a true Alliance, bringing a continued sense of unity to the community, understanding that all of our financial efforts as business owners and community members are greatly strengthened by environmental sustainability.

The Titi Conservation Alliance was started in 2001 by a group of business owners within the tourist industry based around Manuel Antonio National Park, Costa Rica. Recognizing the need for conservation of their natural environment to maintain prosperity for their businesses, this group of entrepreneurs began the Alliance with the mission to promote sustainable development and to conserve the biodiversity of Costa Rica’s Central Pacific Region.

Today, the Alliance is composed of member businesses and individuals dedicated to saving the endangered titi monkey, and its habitat.

Through dues paid by member businesses, donations from concerned tourists wanting to help protect the beautiful areas they enjoy visiting, and the efforts of our staff and volunteers, the Titi Conservation Alliance is working to protect Costa Rica’s Central Pacific region through Sustainable Development, Habitat Reforestation, and Environmental Education.


Members of Titi Conservation Alliance are businesses and individuals dedicated to the conservation of the Central Pacific region of Costa Rica. Thanks to their monthly membership fees, the organization is able to cover an important percentage of the entire budget. They are responsible, aware, dedicated companies and citizens. By visiting their locations while in Costa Rica, you help fund the projects of the Titi Conservation Alliance!
