Explore the most popular mountain biking trails in Alderfer / Three Sisters Park with hand-curated trail maps and driving directions as well as detailed reviews and photos from hikers, campers and nature lovers like you.

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.

Great views at end

easy, with some nice views

Great 3 mile hike. Couple good switchbacks that will get your heart pumping. Overall an easy hike with a couple moderate moments. Good hike to get acclimated to the elevation.

Great hike! Perfect for those looking to just get outdoors and enjoy some scenery.

So many bikers, but all the friendly kind! Great little hike, would make for a great trail run but I brought my Frenchie and he isn’t much of a runner :-)

Great hike. The trails are well maintained and clearly marked. Parking can be a bit of an issue, so arrive early.

The summit has some nice spots for picturesque landscapes. The short detour down to the scenic overlook is also worth it to get a view of the town of Evergreen and the surrounding mountains.

The trails were heavily trafficked by mountain bikes, so keep an eye and ear out for them.

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.

great views, great trails, quiet for most park. come early because after 9 its a little congested.

Decent 4 mile hike. Trail runners and bicyclists were frequently wizzing by, so just something to be mindful of especially if you bring your dog. Mostly shaded but there are a couple places at top to stop and catch a scenic view.

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.

Definitely not a hard trail but was a pretty decent hike

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

Very pretty with lots of options to expand your hike. Brothers lookout is a short way off the trail that ends in scrambling up some cliffs for a pretty amazing view.

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!

Easy hike! Lots of courteous mountain bikers.

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.

We really enjoyed this hike! A bit of an incline on the way up, but overall pretty easy. We did pass a lot of mountain bikers, but everyone had great trail manners; otherwise not too many other hikers. Nice and shaded but still recommend wearing sunscreen.

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