Beginning Wednesday (August 17th) Tyler’s Traverse and Tyler’s Uphill (also known as Tyler’s Access Road) will be closed between the junction of Tyler’s and Larson to the junction of Tyler’s and Duodenum. Please plan ahead as there is no route to ride through this area. Additionally, the entire length of Royal Flush will be closed, as well as a portion of Duodenum between the junction with Tyler’s and the junction with Royal Flush. Forest Service Road 4130 is closed between the junction with FSR 4130-300 and the junction with FSR 4133. The closures on these trails and road are in place seven days a week. Operations may be occurring on any given day, including weekends.
E-bikes NOT allowed on Duodenum
The Duodenum is a lollypop out-and-back ride off of Tyler’s Traverse with an intestine-like hillside on the loop portion. 20 or so heavily banked corners will test your slalom skills.
The loop portion of Duodenum has recently been designated as a one-way trail — which is ridden clockwise.
This trail is maintained by Central Oregon Trail Alliance.
