This is a new section of machine made, Continental Divide Trail that stays outside the Anaconda Pintler Wilderness Area. The trail does continue further after the Sullivan Creek crossing for people who want a longer ride(hope to get back up there and complete mapping it next summer). This is built with a steady grade making for a comfortable climb with some great scenery and a fun trail in either direction. Follow the old Seymour lake trail starting from the trailhead. Look for the new trail off to your right. Please do not continue straight at this intersection, following the old trail, this will take you into Wilderness Area. This trail is well built and easy to follow with CDT signs along the way to show you, you are still on the right path.

Access Info

Turn off the Mill Creek road onto Seymour road(dirt). Follow the main Seymour road all the way to the end, do not turn off it at Lower Seymour or Upper Seymour roads. The end of the main Seymour Road is the trailhead!

 This is a great ride with a gradual climb for about 3 to 4 miles. Great views. We need more bikes on it to break it in. One of the better rides in the area.
