Trail Description
About this trail
First off, there are two parking areas for this trail. I would suggest parking at the first one
you see if it's not full. This makes your ride an up and down rather than a down then up.
This trail is actually a 'dumbell' shaped trail rather than a loop but the main loop is best
ridden in a clockwise direction. The upper loop (Summit trail) is best ridden clockwise as
well. Despite what the FalconGuide says about this trail, the summit is at almost 8500 ft (not
8100 ft) so there's about 1000 feet of climbing. The trail is mostly easy to ride although the
trail does get pretty rocky in spots. Overall the trail is extremely worn due to its popularity.

Review: Great downhill. Bit congested with hikers and riders. Clockwise.

Review: Went clockwise. Next time will go counter. Difficult at times- the downhill is worth it. Go early- hikers and runners

Review: Great Place to ride, lots of trails to ride. I missed a turn and missed the top loop and still got 9 miles in today.

Review: Would be a 5 if there were more miles of trails. The trails on the south side are much better ridden in a counterclockwise direction. Anybody who says otherwise is wrong. Its a faster downhill with more jumps and less switchbacks. It's also a longer downhill. Most of the north side can be ridden in either direction and be tons of fun. Some short techy spots to challenge anybody but not enough to get beginners frustrated.

Review: Southern Half: Rode this half (Evergreen Mountain) of the trail network counter-clockwise in late October. I thought it was a short, but pretty solid Beginner to Intermediate (with 2-3 Advanced obstacles) trail. I went with my wife who is Beginner-Intermediate and she enjoyed it.
Northern Half: A different feels than the Southern Half. I rode in a clockwise fashion from Ponderosa-Silver Fox-Homestead-Mountain Muhly-Bearberry-Sisters. Here's some quick feedback. Mountain Muhly isn't worth a mountain biker's time - too loose and sandy with only one fun small section on the East side - stick to Bearberry. Ponderosa, Bearberry, and Sisters rock. Ride Sisters downhill for Advanced technical terrain. Ponderosa and Bearberry have some solid but fun climbing. I highly recommend putting the Southern and Northern half of the trail together in a figure 8 loop for the best mix of terrain.

Review: This review is the most spot on! Agree with avoiding Mtn Muhly and riding the Evergreen West to East section counterclockwise. The summit climb was great!

Review: Three Sisters is one of my all-time favorite places to hike or ride. It is scenic and has good ambiance. The trail system is well-maintained and well travelled. There are some technical sections as well as some accessible kid-friendly loops. There are a lot of cool rock formations along the way and if you're so inclined you can stop and scramble around or even ride your bike to the summit of Evergreen Mountain. Fantastic area!

Review: Enough loops and trails in this system to provide hours of fun for all different levels. Beginners can advance their skills starting on the gravel loop by the yellow barn parking area, build endurance climbing the West Evergreen Mountain Trail, catch the summit loop and then bomb down the East Evergreen Mountain Trail and catch some air at the bottom on the whoop de doos near the lower parking lot. Advanced riders can work some technical challenge on the Sisters Trail and Silver Fawn is fun for all riders. I like to connect the Dedisse Trail to Silver Fawn, cross the road and climb Evergreen mountain then bomb down and catch any of the connecting trails back to Dedisse. Makes for a fun couple of hours.

Review: Rode the north side of the system yesterday. It has a great steady climb to the summit followed by a great decent. The only negative part of the trail is the water bars by the switchbacks, they ruin the flow of the trail.

Review: Poorly designed trail.

Mountain bikers were an afterthought on most of these trails.

waterbars all over the damn place that ruin the climbs and descents.

nasty rock gardens and tight switchbacks and misplaced water bars/logs pretty much ruin the 3 sisters trail--it's basically a bouldering access trail.

mountain muhly trail is a private road and has "KEEP OUT" signs all over it.

no, I did not get lost.

right past where bearberry picks up from mountain muhly, you get to a gate, followed by a roundabout and PRIVATE PROPERTY signs.

either i'm missing something, or this trail isn't rideable (legally).

I took ponderosa (somewhat technical w/ lots of wheel-grabbing ruts) to silver fox to mountain muhly (4x4 road) to bearberry to 3 sisters (NOT DESIGNED FOR MTB-ing) to hidden fawn (more like hidden yawn....), to west evergreen to summit back down east evergreen.

the east evergreen descent is fun...until you run into those logs mounted on the trail every seemingly 50 feet that you have to bunny hop or slow down for.

I drove an hour to get here b/c someone compared it to buffalo creek.

they couldn't have been more wrong.

the entire network of trails is like some yuppy community park surrounded by a golf course, highschool and affluent mountain homes in evergreen.

there's no thought for flow or anything that would make a good mountain bike trail.

the trail network is TINY.

dont even waste your time on the trails north of parking lot.

I can't imagine why anyone would go to this trail when buffalo creek is less than 30 mins away unless 3 sisters is down the street from your house.

If you go, basically climb the 1.5 miles up east evergreen, turn around, and descend back down (it's about a 5-10 min descent at best).

That whole experience left me with a resounding, "Thats It?!?!" as 3 sisters is a combination of horribly designed trails for hiking/horseback riding w/ about a 1.5 mile descent/climb that doesn't make up for the overall sour taste the rest of the park leaves in your mouth.

most definitely NOT WORTH YOUR GAS MONEY.

Review: I think you are missing that use of the trail is most likely an easement, and perfectly legal. The signs refer to property off the trail/road. Alderfer is a great ride.

Review: Still riding full summer conditions on Dec 5; around 60F in shorts and a jersey!
My first ride here today and thought it was worthy of all the great reviews I've read.
I did a loop on each side of the road, and actually preferred the "Summit Loop" side. I rode CW and the climb was super mellow; at times the climb seemed to have more down than up. Then the descent was spectacular! I was riding downhill faster than I'm used to on my regular rides like Mt Falcon and Deer Cr, and loving it.
Then the other side of the road was a bit confusing for a first-timer. I asked another rider for a recommendation, and either I heard him wrong, or it just wasn't a very good loop. The most enjoyable segment of my loop was going down Bearberry; nice, open, and fast. I thought that some of the switchback/waterbars on Ponderosa and Sisters trail were poorly designed, and I've seen better in other Front Range Parks.
Generally, the trail surface was above average.
You could spend a half-day here to ride a few different combinations.
