Frequently Asked Questions

What is the terrain like on the Hulls Gulch Loop, and how challenging is it?

The Hulls Gulch Loop offers a diverse mountain biking experience.

You'll encounter moderate climbs, like on Kestrel Trail, and fun, flowy descents, such as on Chickadee Ridge Trail. The trail's sandy composition often means it drains well and stays drier than other local trails.

On odd-numbered days, it's designated for downhill bike traffic only and closed to all other users. On even-numbered days, it's open to hikers and equestrians in both directions, and to uphill mountain bike traffic, but closed to downhill biking. Always check the current day before you ride.

When is the best time of year to mountain bike the Hulls Gulch Loop?
