Trail Overview

Sumas Mountain is a 3600-foot mountain in Whatcom County, Washington. There are miles of forest service roads that cross in all directions. You can find communication towers at the summit, but the gate is sometimes locked before you can get to the top. There are three main ingress/egress locations. South Pass Road to the north, and Mt. Baker highway to the south in Deming and another at a Park and Ride location before Kendall, WA at the North Fork Brewery. Access is year round from the north. Others may be gated.


Good road for most of it, but some areas have steep roadways and large ruts and rocks making it harder for dirt bikes.
