An under-utilized trail that adds some miles and some adventure to Boulder Valley Ranch rides.

Features -none-

Part of North Rim is maintained by City of Boulder OSMP, but the majority of the trail is "maintained" by Boulder County Parks and open Space.


North Rim is seldom used in its entirety. Most often riders jump on and off this trail at the southern end of Golf Club Drive to connect to Boulder Valley Ranch. However, a mile of rugged trail runs along the south and eastern edge of the Lake Valley Golf Club and awaits adventurous riders looking to extend loops at Boulder Valley Ranch and Boulder Reservoir.

From Sage Trail in Boulder Valley Ranch, turn north on the crushed gravel trail and head through the gate. North Rim is flat and smooth through a short riparian zone and then turns sharply to the east. Cruise down a short steep section. At the bottom keep an eye out for the unmarked and faint trail heading to the east. If you're moving fast it is easy to miss the trail and pop out on Golf Club Drive.

Crank east along the indistinct trail; don't be daunted by the often very tall grass. Eventually the trail turns north and runs between two fences. Clean the fun, little climb. At the top, North Rim flattens out and then turns west over a small bridge and spits out into the grass next to Golf Club Drive. Hang a right on Golf Club Drive which quickly ends at Niwot Road. Take a left to connect to Neva Road, Left Hand Trail, and Boulder Valley Ranch or take a right to link up with N. 55th Street and Boulder Reservoir trails.

Road this today to make Left Hand into a loop. Trail looks abandoned. I saw snake on Neva, and was concerned about running across them here, because with the tall grass and almost no sign of trail I could run right up on one and not even know it. Next time I woudl just take left hand in and out or go to 55th to Eagle for a loop. Jul 8, 2016
