William F. Hayden Park on Green Mountain offers a challenging system of multiple-use trails for all abilities. The trails tend to dry earlier than many of the foothills parks, making the park a fantastic winter destination.
The park trails include:
- Green Mountain Trail: 6.6 mile loop. Features a challenging ascent to the park’s highest point as well as a mellow section along the base of the park that is great for beginner hikers, runners and mountain bikers. Please note that a portion of this trail follows the park service road that accesses the radio towers.
- Hayden Trail: 1.6 miles. Accessed from the Utah Trailhead, this trail switchbacks up the south side of the mountain and connects with the Green Mountain Trail. Several loop options are possible. It is a slightly easier route to the summit than the Green Mountain Trail.
- Summit Loop Trail: 2.75 miles. A very scenic trail around a portion of the park’s summit. Including exceptional views to the north. This is also the access trail for Box-o-Rox.
- Rooney Valley Trail: 3.8 miles. A challenging single track trail that offers a sense of solitude and remoteness.
- Box-o-Rox Trail: 2.1 miles. Another challenging single track trail considered a favorite of local mountain bikers. This trail includes a lower section that offers more technical terrain than other park trails, and includes challenging rock section with alternate lines.
- North Access Trail: 2 miles. This trail is accessed from Indiana Avenue and accesses the summit from the north side of the park.
- Narrow Point Trail: 1.2 miles. This trail runs from the intersection of S. Alkire St. and W. Cedar Dr. and connects to the North Access Trail.
