Trails
A three mile walking trail follows the lake and wanders through the town of Keomah. If you plan to walk the entire trail, the north and east sides of the park do not have restroom facilities, so plan accordingly. The trail takes you through a variety of habitats, and the keen observer may get a glimpse of wildlife species that call these habitats home. The trail is a combination of grass and crushed rock with some segments using the public roadways. Shorter trails from the lodge and campground connect to the main trail around the lake shore.

Lake Activities
Lake Keomah has an unsupervised swimming beach. The beach is a great place for young and old alike on hot summer afternoons

Anglers can try their luck fishing for bluegill, crappie, largemouth bass and channel catfish. Ice fishing is popular in the winter. Two boat ramps are located around the lake for convenient lake access. A section of the lake shoreline is designated for 24-hour fishing and a fishing jetty is available on the west shoreline accessible to persons of varying abilities.
During the summer the open water, grasslands, deep woods and marshy areas provide habitat for all types of wildlife. Hikers along the park's scenic hiking and nature trails may catch a glimpse of bullfrogs blowing and puffing bass solos, a great blue heron wading in the shallows in search of minnows, or a covey of quail rising at the approach of human footsteps. In the fall, the lake is surrounded by a mass of color from a variety of trees and shrubs.
