This route links Carter Park over to Sidedoor and back. Experience the bike-only downhill trails Sidedoor, Barney Ford and Barney flow in under 15 miles and almost entirely on singletrack.

Start at Carter Park, climb Carter Park to Moonstone. Then take Barney Ford Bypass over to Red Pig. This will drop you down into the Wellington neighborhood.

Take a right on Wellington, then cut through the Country Boy Mine to get to B & B trails (you can also take a right on French Gulch road to the B & B trailhead). Next, take B & B to Rail Dredge (if you want tighter singletrack and a bit more climbing, you can take Turks instead).

Cross French Gulch road and head up Minnie Mine. Take Minnie Mine all the way to Backdoor. Backdoor is a very pleasant climbing grade but you still have to climb 500 ft. This ends on Prospect road, take a right and climb just a short way to the entrance of Sidedoor. After all that climbing, you deserve a descent Hold onto your helmet, Sidedoor is berm-y, jump-y and just plain fun. It's rated a black trail but there are no mandatory drops or gaps and many features have a ride-around.

Backdoor puts you back out at Minnie Mine. Head down, then take a right on X10U8 (Extenuate, get it?). You'll follow this all the way back to the B & B trailhead. Take B & B and then make a right on V3. This is a bit a climb (and you'll wonder if it's more fun downhill, yes, of course it is.) You'll climb this to Barney Ford. The first part of the trail is multi-use and bidirectional, but when you get back to the intersection you turned off for Red Pig, Barney Ford becomes a bike-only downhill jumpline through the meadow.

Cross the road and you'll be back at the top of Carter Park. Take a right on Barney Flow for your 3rd bike-only downhill trail of the day (or if you want something spicy and advanced, check out B-line). Then head back down the Carter Park switchbacks and to where you started.

This section of the trail features the lower half with larger booters and hips. I thoroughly enjoyed sessioning this particular section; however,...
