Perfect, easy short hike for winter. If this was done in summer, I'd give 3 stars that are because it is boring and too easy. First snow day, beautiful Aspen trees covered with snow and ran into some deer. Thumbs up! Parking was only filled with 4 cars at 9 am.

Super easy trail, and peaceful trail... loved it!

Good trail for me to get used to altitude!

I went her at the recommendation of my local bike shop and I had a great time. Was just by myself but decided to not look at the trail map and just go where I thought looked more interesting. Ended up staying and going up and down again and again for almost four hours. Next time I will have to bring my climbing shoes though as I found some nice bouldering spots just off the trails. Was fairly crowded and a fairly easy but pleasant downhill ride. The times I was going uphill wasn’t bad and I would say with some of the rocks and logs in the trail could be considered a medium.

gorgeous in the winter!

easy, with some nice views

I took a left at the loop and if you want to space out the parts where you climb up, I suggest doing the same. There are also some parts of scrambling down rocks so wear good shoes!

This was a pretty and fun ride but it is definitely rated wrong. I got here thinking this would be a green level ride and the exact trail shown is mostly blue with some black, we walked our bikes for a good portion of the up hill and some of the down hill because it was way too steep! Overall a good ride but I wouldn’t bike it again.

Awesome trail! I would recommend doing this backwards from what is shown on here, as the “back half” is much more fun and up and down. The “front half” on this map is very much the same, sloping downhill the entire time. The lookout point is also great. Great trail for running, biking, the lot! Should be rated more difficult than it is - the evergreen mountain trail is shorter and follows nearly the same route but is shorter, and it is rated as “hard.” This, however, is longer and somehow rated “easy.”

Nice hike, though the loop as shown on AllTrails actually appears to be a loop of the Ponderosa trails, three sisters trails, and the brothers lookout spur. we're unaware of an official brothers lookout loop other than once you've already made it to the top. the views were great, but get there early. We parked off the road since the trailhead had long ago filled with mountain bikers and early bird hikers.

Beautiful and easy trail. We saw lots of deer. It was fairly busy but not annoyingly so - we went around Noon on a Sunday.

Great time and great view

The trails are well marked and beautiful scenery. This is one of my favorite trails to go on. However, I would suggest to get there early as the parking lot gets full & it’s a very popular hike.

Although not listed above this trail does indeed allow mountain bikers. Months ago we decided to hike only trails that do not allow bikers because it takes away from our enjoyment greatly when a biker just flies by and runs us off the trail. Beautiful trail but we were disappointed.

Too busy, no parking, nothing special on hike itself.

Really cool hike through pines, clouds and mountain meadows. The trail was great for our 5 month old pup who loves trail hiking. It was a bit rainy and very foggy out today but it made it even more of an adventure. We only saw 3 others out on the trail so a nice and quiet hike today.
Very well marked and the trail is taken care of you can tell.
overall great hike with amazing views, which we will have to come back to actually see those views off the Mt.

Easy hike up Mount Muhly and recommend for everyone!

This is a borderline great hike. The views at the top are simply spectacular. There is a ton of wildlife in the surrounding woods. The trail is well marked and half of it is shaded. The parking lot was full on the weekend but the trail itself was not that busy. Well worth the trip!

This hike was beautiful and easy. I plan to take some visitors here in a few months! I agree with an earlier review about taking a picture of the map before starting, or taking a paper map with you on the trail to make sure you’re going in the right direction.

Very easy but heavily trafficked trail. I recommend taking a picture of the map at the trailhead. This is not really one solid loop but a combination of multiple trails. It can be a short 1 mike hike or a long 10 mike hike depending on the combination of trails chosen. Lots of bikes and trails can get quit congested. This is a great trail for families with young children.

Heavily Traveled on the weekends. Not lightly traveled as the description says. Parking is difficult to find as well.

A really sweet decent after a pretty techincal uphill. For the initial hour of climbing I had to hop off of my bike 3 times. It was a pretty hard climb but the drop is awesome and steep. Some sweet switchbacks and rock lines make this trail a good option.

Nice hike! Great view on the rocks at Brothers Lookout. Only ran into a few other hikers on a weekday morning so not too busy.

Great for a hike with kids. Lots of different trails to make it longer or shorter. Very busy on a Sunday morning.

Nice way to get away from the city and have an enjoyably lazy walk on some pretty trails to get back to center.
However “lightly trafficked” is not the way to describe these trails... but I’ll definitely be back.

Peaceful and beautiful!!!

I went about 7:30am today and while the parking lot was mostly full, I only ran into a handful of other hikers. Plenty of open space and lightly wooded areas to take in. I didn’t see much wildlife but there are pockets of wildflowers growing and I was lucky enough to see some hummingbirds. Trails are clearly marked. It was a nice, easy Saturday morning hike!

This was a nice trail with light traffic. The trip to the top of the summit trail is worth the views. The loop itself is ok with an equal amount of sun and shade. The only reason I can’t give it a five is because the views aren’t plentiful, but still a good trail for those who enjoy the exercise and not crowds.

I thought this trail was kind of boring, but still good to get out to a place with no snow in March, which is when we did it.
