Tramway connects Road 543 to The Colorado Trail, but there is no reason to include it on your ride at Buffalo Creek. It's a very steep, rocky, and rooty fire road, and there are several much better singletrack choices. However, it should be included on a map, if for no other reason than the official Forest Service Trail map includes it and you might confuse it for a real trail. If you have parked at the Buffalo Creek parking area, Nice Kitty
, Shingle Mill Trail
, or Morrison Creek Trail 724
are your best bets for getting to the Colorado Trail.
