I love this trail, as it’s pretty easy and it always has great views. Also, you’ll always get up close and personal with the wildlife (today I saw a ton of deer and what appeared to be turkeys?)... I always add the Nelson Loop for extra mileage. I went counterclockwise today: it was 2.4 miles to the Nelson loop and then another 1.3 miles uphill to the “middle” of the loop. Another mile back down to complete the loop for a total round trip of 7.11 miles. I’d recommend going clockwise on the Nelson loop as it is 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.

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.

Antelope over to 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.

I just wanted to follow up on @AmandaNowak's comment. The Antelope trailhead indeed only has about 10 parking spots and no parking allowed along the street. The Bitterbrush trailhead on the other hand has 2 huge parking lots. These 2 trailheads connect up and it's about a 2 mile hike from one to the other (one way). I think it's a little bit of an easier hike to go from Antelope to Bitterbrush than Bitterbrush to Antelope, but you'll end up having to go both ways to get back to your car, so if you plan on doing the full distance it probably doesn't matter which trailhead you start at. The directions on this trail will take you to the Antelope trailhead, but you can Google map Bitterbrush Trailhead in Lyons and find that one instead very easily (from downtown Lyons you head towards Allenspark instead of towards Estes like you would for the Antelope trailhead). Also there are no bathrooms at the Antelope trailhead because it's so small but there are a couple toilets and picnic benches under a shelter at the Bitterbrush trailhead.

Wasn't able to do the hike. Got to the trailhead at 10am on a Monday in the beginning of May and there was no parking available. Looks like there was only room for a max of 10 cars, if that. The 2 mile road leading up to the trailhead was all marked no parking.

Absolutely gorgeous every time!! Just wanted to let people know that when I went up here on 2/7, where the Bitterbrush Trail meets with Antelope Trail, there's that gorgeous meadow and prairie dog community to look out on. My friend and I definitely saw a mountain lion walking around far from us among the prairie dogs, so please be a aware that one has been seen very recently!

Beautiful hike, did the Antelope to Bitterbrush to the Nelson Loop, then back down Antelope. We got here about 8am and saw more then 50 deer and 10+ bucks on the hike. Might go a little earlier next time to avoid the influx of mountain bikers we encountered after the half way point. Also, if you get to the Nelson loop, go clockwise to get the best views of Longs towards the top.

Terrible parking, lots of biking traffic. But it was still great! Though we had to stop for a lot of bikers, they were all friendly, the view was beautiful, and we got in a good workout that wasn't too killer. Very close to the town of Lyons, as well.

As others have said, lots of mountain bikes (which isn't a problem) but severely limited parking (which is). The trail itself was a really nice out and back with plenty of wildlife to see.

As others have mentioned, very few parking spots available so I would advise against going during popular hiking times. Lot's of mountain bikers on this trail network, moreso than hikers. Opportunity to see deer, prairie dogs, turkey. I'd list this as closer to easy than moderate, but there is a lot of uphill in the beginning.

There are ten parking spots and no alternate lot. Good luck.

Love this one. Just enough ups and downs. Beautiful colors. Watch out for the mountain bikers, friendly but will run you over if you aren't paying attention.
