Hiked on 11/2/19, started out around 10:30 AM. We parked at the Antelope Trail parking area, plenty of spaces this time of the year. The trail was a mix of snow and mud but not bad at all. We saw many signs of wildlife but only was able to catch a rabbit running across the trail. The trail is very pretty, especially with the snow.

This was a good trail. Easy to follow. There are trails with prettier views, but this wasnt bad. There were a lot of bikers, but they were all respectful of the right of way.

Started at nine and ended at about one. only saw 4 people, one on horseback. It was hot and dry. I consider this on the hard side of moderate due to the elevation gain and overall distance. Maybe on a cooler day it would be easier.

Lovely hike, nice views and great work out! You feel challenged but without feeling wiped out in the end. The trail round trip is exactly 6.4 miles.

We did the outer loop of Nelson instead of the inner, which is what’s shown on here, and logged 10.08 miles. Only saw two people on the Nighthawk trail. Once we got to the part where bikes were allowed, we saw maybe 6-7 bikers but only one other hiker. Was pretty surprised at how feel people there were considering we started at noon on Saturday of a holiday weekend! Pretty trail, not hard. Bathrooms are nice. Very hot, almost no shade. Saw lots of prairie dogs on Bitterbrush!

I wouldn't hike this one again, due to its popularity with mountain bikers. (I saw 3 other hikers, 1 trail runner, and 30ish bikers.) Also, lack of shade on the trail and the TINY parking lot at the Antelope Trailhead. I lucked out that someone was leaving right when I arrived, but ya can't count on that. Highlight was spotting a 3-inch praying mantis moseying across the trail.

great views, just needed more time to finish it, but will be back!!

Hiked this trail on a Wednesday after work and it was crowded with mountain bikers!! Hikers, beware. There was a ton of wildlife - in particular prairie dogs were everywhere, which was cool to see but there were also lots of bugs. Come equipped with spray if you’re taking this one on.

Beautiful day for hiking. Arrived at 8 AM and finished out and back in 3 hours and 45 miles for a total of 9.4 miles. Beautiful views, abundant wild flowers, butterflies and only saw about 10 people. Hike is definitely on the easier side of moderate. Not much shade so go early. I would also strongly suggest wearing hiking pants as the path can get narrow with some thorny and itchy plants. Would definitely do again.

Beautiful. Boulder county parks dept and Boulder youth core were out working on a portion of it. Lots of mountain bikes out. Probably 70 percent bikers 30 percent hikers. Trails for bikes seem like a good mix of Rocky areas then a lot of flowing smooth trails with berms at some of the turns. Limited parking to like 8 cars and a detour needed at the time from 36 that added about 5 minutes to get there from the east. At 10am there were 2 cars. 1230pm on a Friday lot was full with several cars passing through

We enjoyed hiking the Nighthawk trail today. We went to the Homestead and clocked 10 miles total in about 5 hours. No dogs! No bikes! What a blessing! Lots of little wildflowers have sprung up and it was just a gorgeous blue sky day. We saw about 5 mule deer hanging out in the shade. Note: This isn't a good hike to do on a hot day; there is very little shade on this trail. You'll pop into the ponderosa forest here and there but don't attempt this on a hot day unless you have sun protection and lots of water. Cheers!

Antelope, Bitterbrush all the way through Nelson Loop was all open as of end of May 2019. Pretty rolling hills and shrub forest with the open spaces as green as it gets this time of year. Quiet hike, a mountain biker every once in a while, lots of mule deer all the way through.

Moderate incline and gorgeous views of the plains and valley. Good to go with a varied group because you can turn around whenever

Very nice loop trail and a great workout for a fast-paced walk which is how I did it. The views of Long's Peak are a nice payoff at the halfway point of the loop. The trail was in great condition, just a few very minor muddy spots. As others have noted, the Nighthawk section is much better for hikers as there are no mountain bikes. On the Bitterbrush segment I was frequently having to dodge out of the way of mountain bikers who came up behind me at high speeds and didn't bother to announce themselves. Kudos to the small minority (20%) of riders who did announce themselves and the number of bikes that were coming along after them. The other downside of the Bitterbrush section is that a lot of the trail has been contoured to be optimal for mountain bikes (think of a u-shaped gully) and isn't great for hiking on foot. All that said, it's a very nice loop overall with great views and is easy to get to.

Delightful hike. Steady incline on the way out, but not strenuous. Nice vistas to look at the whole way (so different from RMNP) and well cared-for trail. We didn't make it all the way out, but close. No shade, so bring sunscreen.

I took Nighthawk in and turned it into a loop by heading back on Bitterbush Trail. Great variety in terrain, held my interest. Only a few bits of muddy spots. Tons of deer spotted, heard some turkeys but didn't see them, a Prairie dog town. Didn't spot any rattlers and I was looking.

Tried the trail yesterday and was closed.

Scenic view in the lower Nighthawk trail of the red cliffs around Lyons and very nice views of Longs Peak and Twin Sisters Peaks at the top. Some parts of trail we're muddy.

This is a great trail for running. No dogs or mountain bikers makes it relatively quiet. It is much less rocky than Bitterbrush. Tough uphill running but worth it for the great view of Longs Peak as well as all the mule deer. I also did the Nelson Loop but don't recommend it due to all the mountain bikers. Hope to connect to the Button Rock trail/Longmont Dam area in the future. Note that it is very exposed and as such is not a good choice for midday activities unless you want to be burnt. I started running at 3 pm on an a April Sunday with sunblock and made out fine despite my fair skin.

Very gradual uphill hike. Not very difficult. But the view of Longs Peak when you get to the top is amazing! Would not recommend this hike in the summer. It’s very exposed to the sun. It would be miserable in the heat.
