This ride is generally pretty mellow but there are short sections that can increase the difficulty quite a bit. It's probably not a great ride for a beginner, but if they don't mind walking some sections, then it should be pretty manageable. There are also some sections that can be a bit rocky that might make newer riders uncomfortable.

The bit of the Sisters Trail between Bearberry and Dedisse Trail is actually very technical and fun if you like a challenge. It is on par with Hall Ranch, but not quite as long. There are also a lot of small sections of trail that have deviated from the original due to difficulty, so if you like more of a challenge you can try to stick to the hard stuff. (Though they are technical enough that you may not even think to try them).


The first part of the Dedisse Trail is a nest of trails so it might be easy to get lost. There is one steep section that goes into a small creek where the trail forks after coming out, make sure to turn left here. Once you cross the road, there will be only one main trail.

The Dedisse has some decently steep and loose little climbs. All should be pretty rideable if you have the gas and balance to push through.

Once you get to the Evergreen Mountain trail you have a pretty steady 600ish foot climb over about 2 miles.

At the top, you can choose to do the Summit Loop if you'd like to reach the top and enjoy the view. There is only one tricky spot on this loop. If you take the loop counter-clockwise, the up portions are a little more technical. There is a scenic off shoot about 100 feet before the actual loop which can mess you up if you hope to go CCW. It's a short off shoot so not a big deal if you accidentally take it.

The back side of the Evergreen Mountain trail has a few rocks but nothing of note. Follow it to the west and north on your way to the Sisters Trail. On your way, you;ll incounter a few junctions. At the first one, with Wild Iris Loop, stay to the left. Shortly thereafter, take a left to cross Buffalo Park Rd and another left to join Bluebird Meadow Trail. At the next two
junctions, stay left again to join Bearberry and follow it all of the way to Sisters Trail.

Once you loop back to the Sisters Trail, you'll hit some pretty great technical riding. The first part has a couple tough rock garden/water bar features that you'll have to climb over. The decent off the back side is pretty steep with a couple technical rocks and a lot of tight switch backs.

Once you get to the bottom of the steep section, turn left to join the Dedisse Trail once again and follow it back to where you began.

Tough blue loop, but a good one overall. I'll try counter-clockwise next time for hopefully better downhill. Sisters Trail was too hard for me. GL. 14.1mi — 2h 10m

Trail was very dry. Certain sections were very technical and required some 'hike a bike' for flatlanders like me. Overall a very fun trail. 13mi — 12h 30m
