Great workout hike. Another one of my local favorites. The first time I did this trail I did the whole loop and did the hiker shuffle back to my car. I went up the nighthawk way and looped back down. Was a solid 9+ miles and I don’t even think I stopped. Oops. The views and scenery are amazing and I really liked the switch backs. Views are breathtaking.

This is a great trail trail that remains fairly flat throughout. There is a waterfall half way in which is really nice and a couple meadows you walk through with the mountains in the background. We went early in the day and saw few people. Good hike with dogs as well!

We hiked this trail on a beautiful Tuesday afternoon. The gate was closed so we parked at the side of the road. Very easy trail we hiked 3 miles in and back out. Beautiful pine forest with river always present. We stopped for a snack where the trail crossed the river. Great spot just us the breeze and the rushing river. As far as creatures, we found some pretty fresh black bear scat and some pretty fresh scratch marks on adjacent trees, some mule deer scat and a bunch of butterflies. Nice trail

nice waterfall... not too challenging ... good trail for flatlanders. nice shade, water

I had a great day with my 7 year old.! We took a couple detours due to felled trees and it was difficult to keep socks dry with all of the run off so the child decided to not care, but it was fun the whole way. Light traffic on a Friday morning.

awesome trail for hiking, running and lots of biking.

The ascent up Antelope was challenging but after a bit of climbing there's some fun flowing riding up top. All of the bikers and hikers I encountered were very respectful.

I also hiked the trail a few weeks prior to biking it and all of the bikers were respectful. I quickly recognized that the trail was primarily designed as a mountain biking trail, so I kept to the side whenever any bikes were coming... Common sense

This trail has a lot of people on it. It is great for bikers and runners.

Too many bikers on this trail. My GPS showed 14.6 miles and 1392 ft elevation gain.

I just added this particular route to Alltrails. According to Gaia and my wifes phone app it is 6.9 miles but Alltrails automatically plugs in 6.6 miles. Bottom line is that this is an easy flat trail and the scenery is absolutely beautiful. As a hiker I can say this is the prettiest trail that I'll never hike again. Bikers take over this trail and as a hiker it's a nightmare. We had to step off the trail every 30 seconds for a biker. Although it's a multi use trail the bikers operate as though they own it. They literally run you off the trail and expect you to jump off the trail as they barrel through. I was just trying to make it out of there without being critically injured. Eventually I just starting hiking off the trail. If your a mountain biker then I'd imagine you'd love this place. For me and other hikers.... it's a shame we can't enjoy this beautiful place.

3/13/18: Did this trail today w/my 9 y-o & 17 y-o. We parked in the lower lot but the upper lot has the bathrooms. We took the Nighthawk trail. No bikers allowed on this trail. The only issue we had was when the trailed forked off with no sign. The fork off to the right is what looks like a vehicle made path (what the path had been up to that point for awhile) and the fork to the left is a thin foot trail. We went right because it seemed to be going in the right direction. It wasn't the path but still got us to the same point - where you can take Button Rock trail or Nelson Loop. They need to put a sign at that fork! We took Nelson Loop to the right (east), stopped at the settlement then took Bitterbush trail to the parking lot. Almost as soon as we got on Nelson Loop the mountain bikes started coming. With the exception of the mountain bikes, our favorite part of the hike was Bitterbrush & Nelson Loop. If we do this one again we'll skip Nighthawk. It took us just over 4 hours to hike this. I don't think I'd brave this one in the summer. Not much shade. Must be really hot in the summer. We didn't think it was difficult but the kids complained that it was too long.

LOVE THIS TRAIL but letting everyone know that it is closed currently for what looks like flood repairs :( unsure as to when it is going to open again

Maybe my favorite Boulder County open space. There are a lot of places where it feels more like plateau country than Front Range. Bike traffic is a big detractor for hikers on the Bitterbrush but it's often worth it due to the awesomeness. Especially love the rock garden area and it's fun to watch the more skilled bikers who can really ride it. A lot of the summer, this trail is a bit too hot. The mule deer here are not particularly afraid of people and especially when they have fawns and will often stand their ground when you meet them on the trail.

If you just want to hike this is not the trail you want to be on. There were so many mountain bikes. Too many to count, very frustrating.

Beautiful hike. Set out at 6:30 AM and didn’t see anyone the whole way up and back. Hiked in 4 miles on the trail to the Wilderness boundary. Hiked out on the 4 WD Road. The road was a bit sketch as there were numerous icy sections, should have stayed on the trail both ways. Take your spikes if you take the road.

Nice hike on a beautiful Saturday. Arrived about 8:30 am to plenty of parking and didn't encounter much traffic on the way up, but friendly bikers thronged the trail both directions on the way down. Encountered a rattlesnake on the trail within sight of the parking lot, but it wouldn't budge, so I backtracked and took Nighthawk Trail the rest of the way. This is a good moderate hike for diversity in terrain and inclines, and it has some nice but not spectacular views. Take a brief detour to Sleepy Lion Trail at the top for some really beautiful views of Longs Peak and the Ralph Price Reservoir in Button Rock Preserve.

Great easy hike with kiddos. Did it early to avoid the heat of July.

Fun hike with the kids! We hiked in a few miles - the river was beautiful, there were many boulders for the kids to scramble up on, and my daughter was thrilled with all of the wildflowers.

Great easy beginner hike. It's only 3.5 miles to where Buchanan Pass Trail starts and it's another 7 or so to the lake. We only did the first 3.5 but there is lots of water for dogs. Park at Camp Dick and the trailhead is close to the parking lot about 300 m or so. Great hike that is relaxing and not strenuous.

This is a very easy hike with very little elevation, so it's great for beginners. We hiked it with our dog, and it was nice because there is a stream most of the way, and a TON of shade coverage. Great for hot days, between the shade and the water. We started at Camp Dick, and the trail head is all the way at the back of the camp grounds. The trail is about 300 feet from the parking. The Camp Dick part of the trail gets you to the start of buchannon pass, and it's another 6 miles or so to the glacier lake. The first 3.5 miles are very flat, with lots of shade and water for dogs.

Nice Trail but near a 4x4 road so sometimes noisy

Went all the way out to Red Deer Lake. Total round trip was 14 miles but worth it. The beginning half of the hike mapped out on this trail log is way less impressive than the back half out to Red Deer Lake. Beautiful hike, worth the effort.

Loved this trail! We did about 4.5 miles in from the parking lot. Next time we are shooting for the overlook! Total of 9 miles and there were wonderful things to see the whole way, wildflowers, birds, bees, rabbits, butterflies, views, and the moon was even visible. Relatively gentle incline for people that hike regularly. Nice elevation gain making it still a good challenge. Sensory overload in the best possible way. Lots of bikers on the trail with everyone being courteous with each other along the way. First 2 miles does not offer a lot of shade in the summer months so sunglasses, hat, and SPF are a must. Breaks into trees throughout after. Did some jogging as well, not a lot of loose rocks to slip on as I tend to do. :D

Did a 5-mile out and back. Was along a river but flowing too fast for dogs. Tons of downed trees. In the 5 miles it was about 550 feet so I'd rate that part easy. No views on this part of trail. Low-ish traffic on a Saturday. Would give more stars if it had views or some variety. But maybe that's later in the trail. The part I did was sort of run of the mill.

Hall Ranch is fantastic for train running.

One error on the Wildlife section; the deer are mule deer, not whitetail.

Beautiful! Some significant inclines throughout. There are only two tiny streams for your pet to get a drink so take along extra water. My GPS logged 7.5 miles, in and out, to the parking area. The old trail is closed for revegitation so you must take the new one that climbs over a small mountain. A lot of this trail is a roughly graveled access road, which is very hard on a dog's feet. There was moose, deer, cougar and bear sign when I hiked it in June. The cost of access to this area is $6; machine accepts credit cards.

Good easy trail. Did about 7.5 miles in/out. Some snow and lots of water on trail. Quite a few downed trees as well.

I go here often, especially in fall, winter and early spring. It's possible to hike from the main TH off Hwy. 7 west and connect with Buttonrock Preserve trails. I have seen lots of wild turkey on this trail. Watch for rattlesnakes in summer.

April is a little early to ride this trail due to snow drifts but still pretty. Pleasant Valley Resort and Spa is just down the road and is a VERY neat place to stay by yourself or with your horse.
