I hiked this trail to the top of Chestnut Mountain Sunday 06/30/2019. It's a nice trail but nothing spectacular. A variety of little things bothered me. For most of the trail there is no visibility for any viewing. There are a few spots where you can stop and see the landscape below and also the rocks but overall the view is blocked with trees. Even at the top of Chestnut Mountain you can't see much to the west or north. The trail is a single track for about 70% of the way. The bikers were all respectful and moving slow enough that you had time to get out of the way, but in a lot of places there was nowhere to go but to leap into the high weeds and bushes. That leads to the next concern - snakes. I saw one in the trail that moved away as I approached, but, frankly, I'm not interested in leaping into high grass to avoid a biker only to land on a snake. It didn't happen but I'd rather have some room. The trail if taken all the way to the top will give you a good workout and will take anywhere from 1.5 to 2.5 hours to get to the top depending upon your fitness level. I would do it again but it's not high on my list.

Trail is good up until the last 1.5-2 miles to the top. Turned around about .75 from peak because didn’t want to deal with the snow but totally doable and lovely!!

The trail was beautiful with views of mountain ranges, wild flowers and open plains. We ended up hiking around 12 miles roundtrip. The only downside is the close proximity to the freeway, but this could also be viewed as a plus if you’re looking for a easy to access trail.

Hiked up to Chestnut Mountain which is about 4.8 miles out from the trailhead...so 9.6 miles roundtrip. This was suffice for me as I was hiking for views. Great view of Frog Rock from the Chestnut Mountain trail.

Walked 3 miles in and then back. Good steady uphill pull. Recent snow/rain made for a bit of mud but not bad. I wouldn't classify this as grueling but it might be if you are not a regular exerciser.

Went to the top of Chestnut Mountain versus going to Frog Rock - a great hike with beautiful views of the valley and other mountains, and not too many people. We went up about 4.8 miles to the top of the mountain making the round trip hike a little less than 10 miles. Pack a lunch and enjoy it at the top! http://m.outsidebozeman.com/?url=http%3A%2F%2Fwww.outsidebozeman.com%2Fplaces%2Ftrails%2Fbiking-trails%2Fchestnut-mountain-trail&utm_referrer=#2824

Good trail, nice length with some great views. traffic was more moderate than light, so if you're looking for privacy this might not be the trail for you. The first 1/3rd of the trail can be a bit grueling with a continuous, sometimes steep incline. Some fun and accessible rock climbing at Frog Rock with wonderful views. Good trail for wildflowers if you're looking for some nature photo opportunities.

You lose the highway noise quickly. The wild glowers and views are incredible. You 'll see the Bridgers and Abarokas on this hike. The elevation gain is greater than it says here. Steep. But doable. Go to the next switchback and then the next. It 's worth it .

This was a great trail. Would be five stars without the highway noise. Nice views, definitely worth checking out. I got within 15 yards of a chattering rock chuck, and flushed a blue grouse.
