Overview

 
East side
This is probably a better climb than the "west" side. The west is a blast to descend.
 
Scenic climb
You pass some gorgeous scenery on these trails. Great trees.

Alderfer 3 Sisters (A3S) is a decent sized JCOS park with recently added terrain and trails. It lies south of Evergreen. It is a little bit farther away, but is definitely worth the drive. There is a trail on the south side of the park that goes up to the top of Evergreen Mountain, and provides a nice climb with a sweet descent. Some of the rest of the park is decomposed granite track with some tight switchbacks and some fun, although relatively easy, technical terrain. The park can also be combined with the Denver Mountain Park Dedisse Park to the east, making for a longer ride, all on singletrack or old closed doubletrack. The park is a little higher in elevation, so sunburn comes quicker, and altitude (almost 9,000') affects the lungs, too.

There are 2 trailheads, both on the same road. Both now have bathroom facilies, although the west TH has a much larger parking lot and bathrooms.

You can make a nice stop at the top of The Brother, one of the other formations in the park. You can bike to the base of the 3 sisters, but to scramble up them, you will have to leave your bike. I recommend not scrambling on the rocks in hard biking shoes. Exposure exists!

My preferred ride is to ride everything in the north side of the park, then cross the road over and climb up Evergreen mountain from the east, then finish heading north and descending back to the THs. Sweet ride.

90% of the park is nice singletrack, the rest is old, closed doubletrack, which is basically 2 parallel singletracks.

Getting There

 
Gneiss playground
Nice and grippy, usually even when a little wet.
 
Stiff switchback on Summit Trail
This is a hard corner to make going up. And down. Tight and technical.

From JCOS:

To access the park, travel south of Evergreen, Colorado on Highway 73. Turn west on Buffalo Park Road, approximately 1 mile to the east parking lot. A second parking lot is located another 1/2 mile along Buffalo Park Road. Motorized vehicles are confined to the parking areas and roadways.


When to Bike

 
Gettin  tricky wid it
Nice little tech spot on Summit Trail.
 
Sisters Loop
Sometimes, you just gotta walk it.

This park can hold late season snow and the south side (Evergreen Mountain side) can get muddy after rains/snow. Best times to ride are April-November. The sun can definitely be a factor at altitude. Most of the trails are fairly shaded.
