Whether you’re just driving the Cascade Loop or spending more time exploring the North Cascades, keep in mind that Rainy Pass is a hiking hub with several excellent walks of varying length and difficulty. Among the most popular options are the four-mile (round trip) hike taking you to Lake Ann, and the seven-mile Maple Pass Loop offering flower-filled alpine meadows and up-close-and-personal views of the rugged peaks typifying the North Cascades.

Access: Follow Highway 20 to Rainy Pass at milepost 157.5. Park in the rest area on the south side of the highway where you’ll find the trailhead for Trail No. 740, signed “Lake Ann-Maple Pass.”  A Northwest Forest Pass is required to park (day passes can be purchased at the trailhead).

Leave It Better Than You Found It:  This should be every outdoor user’s goal. Pick up trash left by others, pull noxious weeds along your route, disperse old fire rings (they encourage more fires), throw branches over spur trails and spurs between switchbacks (make it harder to do the wrong thing than the right thing).
