Miller Creek Trail #367 or as it is commonly known, Creekside Trail is part of a network of trails serving the Thumb Butte area. It can be accessed from the Thumb Butte parking area using Trail #326, or from the other direction using Trail #332 or #392. This trail criss-crosses Miller Creek, a babbling stream that grows during the first weeks of spring when snowmelt trickles down from the surrounding high country.
This is the last part of singletrack for the Whiskey Off-Road - 25 Proof Course, so beware in the spring as many bikers are training for this event. While there are a few small obstacles, the highlight of the trail is a large creek crossing near the Trail #332 intersection. Be careful crossing this as even some pros have problems with it.
