Lyman Lake State Park is an Arizona State Park built on the shores of Lyman lake, a 1500 acre reservoir on the Little Colorado River.

Lyman Lake is located at an elevation of about 6000 feet and, because of its size, one of the few bodies of water in the region with no boat size restrictions. The Lyman Lake State Park is a popular destination for all types of water sports including jet skis, wake boarding, water, skiing, swimming, fishing, boating, canoeing, kayaking, among others.

Because of its elevation, the temperatures in the park remain cool during the summer. This makes it a popular destination for visitors who wish to escape the heat and enjoy a relaxing day out in the water.
