    Table of contents

    Mount Sawyer via Tonga Ridge Trail is a 9.0 km hike in Mount Baker-Snoqualmie National Forest. This hike gets you up on a little summit with less than 500 m of elevation gain, and the trail doesn’t tend to be too busy. There are some loose, steep, dry sections where poles are recommended. The bugs on this trail can also be bothersome, so bring potent spray.

    Route Description for Mount Sawyer via Tonga Ridge Trail

    Mount Sawyer is an easy little peak to climb, the entire mountain possible in less than 10.0 km. The trail has a bit of a steep finish with some loose rock and plenty of too-friendly mosquitoes, but other than that, it’s a straightforward route.

    Begins from the parking area at the end of the road. Tonga Ridge Trail is usually well-maintained and easy to follow. It’s a straight shot to the foot of the mountain, with the vast majority of the elevation gain happening from the base of the mountain to the top.

    Where the trail forks, keep left onto Mount Sawyer Trail. You’ll have a couple of wide switchbacks to help you up the mountain, but poles are still a help as you approach the top.

    After enjoying the views, simply return to the trailhead on the same trail you came up on.
