The primary course is a 10 mile loop that combines the Blue Wing, Koasati, and Whoa Mule trails.

Trail conditions reflect typical Louisiana State Park terrain. Routes are mostly flat with minimal elevation change and feature muddy sections, exposed tree roots, and natural trail surfaces. The park trail system includes nearly 10 miles of woodland trails and an 11 mile canoe trail.

Lake Bistineau State Park sits on the western shore of the lake and contains upland mixed hardwood forest plus stands of cypress and tupelo trees. Park facilities listed include two boat launches, hiking and biking trails, playgrounds, camping, cabins, and fishing.
