Adams Gulch and Griffin Butte Loop

The average mountain biker can expect to complete this loop in approximately 2 hours and 50 minutes. This duration can vary based on your fitness level, riding speed, and how often you stop to enjoy the views.

The loop can be ridden in either direction, offering different experiences. Riding clockwise involves a challenging climb up the Adam's Rib Trail Junction and Griffin Butte Connector, followed by a fun descent.

The counter-clockwise direction can include some hike-a-bike sections on steeper parts.

You'll find a diverse mix of terrain. The singletrack is often described as "buff and flowy," but it also includes some rocky sections and challenging talus fields, especially on the counter-clockwise route. Expect significant elevation changes, with the Griffin Butte Connector having an average 9% grade, steepening to over 15% in parts.
