Upper Bitterbrush Trail

Trail Meter: 

The yang to Lower Bitterbrush's yin. This trail is pretty mellow, wide and only has a couple of easy rocky spots. It's the way up to the Nelson Loop if you are planning on making a bigger ride out of your trip to Hall. From the bench near the trail junction of Lower Bitterbrush and Antelope, head west and downhill. This downhill is short followed by an uphill that will take you past another great prairie dog town and onto the ridge line. Over time, this trail has seen a lot of wear from the large number of people on it. Please try to stay in the middle of the trail as much as possible to allow for the singletrack to stay single.

This trail tops out at the base of the Nelson Loop. You'll notice the trail widening after a short section of roots and rocks. This is a popular spot for hikers and bikers to catch their breath before heading up!

Coming down:
This trail is a ripper on the way back down! It's got great flow for the intermediate rider, with a lot of fun swoopy turns that really put a smile on your face. Two words here. One, this trail has a lot of loose sandy stuff on it. People regularly come down this trail too hot and find themselves upside down before they can blink. Two, this is a super popular trail with a lot of blind corners and a lot of people (many who will be scared by bike riders coming downhill and likely unprepared to avoid you). Keep your speed under control and be respectful. Going downhill, you're the one who yields - and that doesn't mean riding off the trail to avoid other people, man! It means slowing way the hell down and stopping if necessary to make sure that uphill traffic isn't afraid/startled/put out/killed.

Good between antelope and nelson loop with barely any wet sections

From redstonecyclery via Twitter: Bitterbrush trail at Hall is absolutely perfect right now. Antelope is muddy and Nelson Loop is closed. #boco_trails http://t.co/jWJDf6ItKP

from Redstone Cyclery via Facebook: Hall Ranch was great from the parking lot, thru the rock garden and all the way to the loop. Antelope is still muddy and Nelson Loop is still closed. Bitterbrush couldn't be any better though!
