The Lake Hennessey Shoreline Trail starts at Moore Creek Park Trailhead and follows the contours of the lake for fantastic views of the shoreline, lake and wildlife.

Alta Hennessey Trail is a dirt road that loops through the hills on the northern shore of Lake Hennessey.

Hikers, bikers and equestrians can park in the Moore Creek lot and hike the Chiles Creek trail to the trailhead.

On the northern shore of Lake Hennessey, the trail connects to the Shoreline Trail for a nice loop back to Chiles Creek Trail and the parking lot.

Sam the Eagle Trail is a single-track trail that parallels Alta Hennessey and the Shoreline Trail and provides more of a challenge in elevation change through the grassy hillsides of the eastern shore of Lake Hennessey.
