Runner Notes

Nighthawk is off limits to cyclists but Bitterbrush Trail and Nelson Loop are both open to cyclists so keep a look out and be considerate as there's some pretty technical stuff.


Starting with Nighthawk Trail and running clockwise, you'll start off on a wide, maintained trail and move along to singletrack with various rocks and roots. The first 4.5 miles will be almost exclusively uphill. There are trees scattered around the trail that provide some shade to catch your breath and enjoy the view before soldiering on.

Once your reach Nelson Loop, you may go either left or right to connect to Bitterbrush Trail. This route goes to the left. Expect to see cyclists at this point. You'll hit some great downhill singletrack before meeting up with a rocky section. About 7.5 miles in you'll reach the split - left goes to Antelope Trail but stay to the right to keep on Bitterbrush Trail. You'll have 2.5 miles of trail to reach the main trailhead and many technical rocky sections.

Flora & Fauna

Mule deer, prairie dogs, birds, and pines.

History & Background

Arapahoe and Cheyenne Indians lived in the area. For over one hundred years, more than 20 different families lived, farmed, quarried, ranched and logged in the Hall Ranch area.

Easy to extend for 15+ miles. Try Antelope trail for 500 ft elevation gain hill repeats.
