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.
