Ecosystem Preserve and Native Gardens

The Calvin Ecosystem Preserve & Native Gardens is a one-of-a-kind oasis in the city of Grand Rapids.

The preserve’s 100+ acres of native plants and natural habitats offer boundless opportunities to explore and connect with nature. Come enjoy wandering our trails, enroll in a class or educational program, or just sit and relax.

This incredible resource is open to all who wish to join us as we conserve, restore, protect, and appreciate the wonder of creation.

Celebrating 40 Years of the Preserve!

We’re marking our 40th Anniversary with events all year long. Join us, starting with an Earth Day reception, a summer video feature, and a special open house during Homecoming Week in September.
