Crystalline ocean

our mission

Nicoya Peninsula Waterkeeper is a non-government organization, whose mission is to monitor, protect and restore water quality in the coastal watersheds and marine ecosystems between the Cabo Blanco Absolute Nature Reserve and the Caletas-Ario National Wildlife Refuge through research, field work, education and advocacy.

We want these watersheds’ water quality and scenic beauty maintained and restored to flourish, for present and future generations to benefit from and enjoy.

We are the guardians of clean water for the South Nicoya Peninsula, filling a critical niche in the coastal area as the watchdog, steward, and voice of the ocean and coastal watersheds.

Crystalline ocean

our vision

Nicoya Peninsula Waterkeeper’s vision is to have fully functioning ecological, biological and hydrological aquatic ecosystems in the ocean and the coastal watersheds.
