Hall Ranch, Bitterbrush and Nelson Loop Trail is a 10 mile moderately trafficked loop trail located near Lyons, Colorado that features beautiful wild flowers and is rated as moderate. The trail offers a number of activity options and is accessible year-round. Horses are also able to use this trail.
The Bitterbrush and Nelson Loop Trails are fairly difficult mountain bike routes that form a lasso trail near Lyons, CO. Unlike many of my other trail guides, this one is definitely a little more strenuous and technical. If you are riding a bike, prepare for steep climbs and rapid descents. There are some tricky corners and numerous rocks and roots in the trail. There is also great scenery, lots of wildlife, and a heck of a roller-coaster ride. Although this trail is good for hiking, many hikers choose Nighthawk Trail, which runs off of this trail and takes a similar route. HISTORY: In 1885, Edward Lyon settled the land that later became Hall Ranch. The sandstone quarries just to the east of Hall Ranch are made up of 52 smaller quarry pits, and these were also established by Edward Lyon. Electricity was first introduced to the region around 1912 when the Longmont Aqueduct, which supplied water from Longmont Reservoir to the power plant, can still be viewed on the north side of Hall Ranch. The name Hall Ranch was first applied to the land in the early 1940s when Hallyn and June Hall purchased a chunk of the surrounding land. WILDLIFE: Hall Ranch is rich in wildlife. It is considered a crucial nesting habitat for numerous birds. Predatory birds such as golden eagles hunt here and are always on the lookout for a feast of prairie dog or squirrel. White tailed deer and rabbit are also commonly seen from the trail. One of the better places for observing wildlife at Hall Ranch is in the meadow at the junction of Bitterbrush and Nelson Loop. In addition to the cute and cuddly critters, don't forget that rattlesnakes love sunning themselves on the trail. Leave them alone, and they're usually pretty docile. GEOLOGY: The oldest rock in the area is about 1.7 billion years old and the youngest is approximately 62 million years old. The rocks are a mix of sandstone and granite.
Definitely a moderate hike but a great workout. Good views here and there. Deer everywhere. Lots of bikers on Nelson. Overall though great hike.
Overall good hike on Nighthawk Trail. Sunny and very hot when I was there, but there was a few shady spots to escape the sun here and there. Great views of Long's Peak.
enjoyed nighthawk trail. no bikes or dogs... a few horses and not crowded. nice view. not strenuous. then had a well earned lunch in Lyons
Beautiful hike but a lot of bikes
Obnoxious mountain bikers allowed. Don't bother hiking here. Same for most Boulder County open space. The bikers control it all. Sucks for hikers.
Great for mountain biking. Not as good for hiking. I prefer going hiking in this area at Heil Valley Ranch on US 36 close to Lyons.
Did the big 10 mile loop yesterday. It was so hot and there was no shade. The trail it's self was nice though:) next time I'll just go when it's cooler outside.
Very nice trail to work on biking over rock features.
A nice slow and steady hike. Can't bring your dog which is a bummer.
Great trail. Great workout.
I love this trail, the rock gardens are fantastically challenging. You have to hit lines perfect to not end up pushing your bike.
Great trail run , wish I had mountain bike for the way back , tough workout
Took my horse up Nighthawk trail was a bit too rocky there is no shade and I guess I'm a little spoiled but I won't be going back. Where are the trails around here with trees that provide shade?
Great trail, lots of fun to mountain bike. I just moved out to the area from Kansas, so I had to get used to the trails being all uphill for at least half the ride. But once I got into shape for the mountains, the rock garden is by far more fun than any trail I rode in the Kansas City area.
