A really nice section of woody trail which connects the Sourdough to the Left Hand Park Reservoir Road. This section of the Little Raven Trail is less technical than the Little Raven continuation to the west, but still serves as a high elevation lung-buster climb to keep you in check.
This road (also known as FS104) can serve as a useful connector to singletrack trails in the Brainard Lake area, so BMA put it into our trails database. It's wide and not exceptionally techincal, but can be steep at times. Typically, mountain bikers use this road in two contexts:
1) park at Brainard Lake Trailhead and use Left Hand Res Road to climb up to the Little Raven Trail
Formerly known as the Wapiti-Baptiste Trail, this trail had it's beginnings as a cross country ski route. In 1993, intrepid mountain bikers cleared the deadfall from the trail and got the Boulder Ranger District to administratively add bikes to the "appropriate uses" in their inventory (you are welcome). From that point on the effort to create a ridable line began. Work by BMA trail volunteers laid in a 4 to 6 inch line in the rockiest section made this trail even more desirable.
Kiss the sky baby. The 505 Road from Eldora to the peak at Caribou is a serious grunt of a climb. Downshift and make the best of it. If you are looking for a sweet singletrack experience, do yourself a favor and go somewhere else. If you like pain, long epic rides, or getting up close and personal with the high country, come on and give 'er.
A road?!? Seriously, it's a road, but it's not for the faint of heart.
Coney Flats Road starts at the NW end of Beaver Reservoir. It is a gnarly babyhead laden 4WD road only for extremely modified vehicles. Climbs aren't very steep, just rocky. But it leads you to Coney Flats Lake, offering beautiful views of Buchanan Pass.

If you're in the mood for a technical feast, then this is the place to be. Although the trail is not steep overall, it is best ridden downhill, meaning west to east. Embedded rocks sized from grapefruits to washing machines abound. The rocks, water bars, and occasional steep section will command your attention the entire time.
Views are scarce as the trail wanders along a forested, low contour on the South Saint Vrain drainage. You may see an occasional moose, Tufted Squirrel, or Gray Jay.
Sourdough South is a rolly polly lungbuster, traveling north-south and paralleling (but nowhere near) the Peak to Peak Highway. Solitude and suffering await you... ok, it's really not that bad if you're mentally prepared for high altitude riding with some loose rocks thrown in there.
You can start this trail from the south at the CU Research Center / Rainbow Lakes trailhead, and from the north at the Brainard Lake trailhead.
Welcome to the Switzerland Trail of America, an old railroad grade that once connected many of the mining camps in Boulder County. History buffs should start here:http://en.wikipedia.org/wiki/Switzerland_Trail. We've divided the Trail into North and South sections because they are not typically ridden at the same time.
