Green Lake Park serves as a natural preserve for hundreds of species of trees and plants, as well as numerous birds and waterfowl.

Friends of Green Lake invites you to join us on a walking tour around Green Lake to learn about the history of the park and facts and features of the plants and birds that inhabit one of the top ten parks in the country.

Meet at the Green Lake Park sign on the west side of the path, between the East Beach and the Community Center parking lot.

We will walk the 2.8 miles around the lake (counterclockwise) to end back at the start.
