Threemile Ridge is a favorite of local riders for its sweat and speed. The labor, mitigated by super-vistas during the first 10 miles on the Continental Divide Trail, gives way to velocity when the bottom drops out for 3,000 vertical feet on a twisted two-track that flows like a tumbling stream. For this classic descent, pack a spare set of brake pads. After the ride, if your brakes still work, stop at the Broken Arrow for frosty drinks and fantastic Mexican food.

The road is in much better shape now and has been fixed up. Work probably done during the '21 fire, so it is smooth all the way to the lookout site and has seen some gravel laid down in places. You can haul your Glamper to Anderson Lookout site w/ your Prius now!
