From the Miller Gulch Trailhead (you can also start about 1/2 mile "down" Boise Ridge Road at the Corrals Trail
trailhead, which cuts out a little climbing), climb the initial hill to where the connector trail meets up with Corrals Trail
. Hang a left on Corrals and enjoy the mellow cruise while it lasts. There is short a "frontage singletrack" that cuts off to your right at one point. Take this if you want to increase your singletrack/doubletrack ratio.
Eventually there will be a left turn for Hard Guy
. Take this and drop down a short distance to where the steep climb begins. Pedal, pedal harder, and pedal some more. If it's a hot day there are a few shade trees towards the top of the trail. Don't forget to look at the nice view behind you.
Eventually Hard Guy
ends at the Boise Ridge Road. Hang a left and follow the Ridge Road for a couple miles of rolling terrain. Keep an eye out for a trail that cuts off to your left (there will probably be bike tire tracks on it). Note that this is unmarked and is the second possible left. It's a short distance after the first left which I believe ends in a dead-end on a ridge (but I haven't investigated).
This is the start of Dry Creek
. Follow this trail out onto the ridge. After a couple minutes the trail makes a sharp turn to the right and there will be a fainter trail that breaks off to the left. GO RIGHT (left is Shingle Creek
Trail). As soon as you turn, the trail starts dropping. Get ready for a winding trail through the trees, some rocks and drops, a few washed out corners, and LOTS of creek crossings which are all rideable. Plan on getting your feet wet! The fun just keeps coming all the way down.
Eventually you reach a fork where the Dry Creek
Trail cuts up a slope to the right and leaves the creek. You can take this all the way back to Bogus Basin Boulevard, which you can ride downhill back to where your car is parked. This lower section of dry creek is of a different character than the upper portion, with lots of ups and downs, and with technical bits that seem to mostly come on the ups.
Another option, and the way I chose to go, is to go left at the fork, and cut across the creek one last time to a connector trail which takes you up and meets up with the bottom portion of Hard Guy
. While this requires a short but steep climb to get back up to the ridge that Hard Guy
follows, it prevents you from having to ride the sometimes busy Bogus Basin Boulevard back down (nice if you ride with your mutts like me :) ).
If you took the connector just reverse your tracks when you get back to the bottom of Hard Guy
(right on hard guy, down, up a short climb to Corrals, right on Corrals, right on the connector back to Miller Gulch Trailhead).
