An amazing journey back in time to the scene of the Mt. St. Helens eruption.

Anthony Harasimowicz


This ride initially takes you up the secluded but strenuous Ape Canyon Trail before continuing to the upper trail segments. As you ride along the canyon near the top of the climb, the views and terrain transform from shady forest to an amazing moonscape. The balance of the ride is across the vast pumice fields on the Loowit and Plains of Abraham trails at the base of Mt. St. Helens with views of several other peaks as well.


Starting from the small parking area at the Ape Canyon trailhead off of FS 83, begin climbing up the shady singletrack of the Ape Canyon Trail (#234). As you head up the trail and turn to the right, the first views of Mt. St. Helens are straight ahead looking from the south. Continue to climb up the well-traveled trail with a few switchbacks and sporadic views of the mountain.

Near the top of the climb, pass the steep slopes and rocky exposure of Ape Canyon on the right with a perfect view of Mt. Adams to the east. Next, ride through the moonlike pumice fields on a short stretch of the Loowit Trail (#216) and toward Pumice Butte where you'll see the remnants of trees that resemble pushed over matchsticks. Continue north to the Plains of Abraham Trail (#216D) with incredible up close views of Mt. St. Helens eastern slope.

Signposts note the trail junctions and mileage and dark volcanic rock cairns help identify the route. The trail climbs and descends along a hillside ridge to Windy Ridge Road (FS 99), but a good turnaround point is at the long staircase just south of the road. Before starting the return trip, catch a view to the north of the top of Mt. Rainier and then enjoy the downhill run on the Ape Canyon Trail.

History & Background

It was early Sunday morning on May 18, 1980 when Mt. St. Helens erupted and leveled nearly 230 square miles of forest and sent 520 million tons of ash eastward across the United States. This scenic ride takes to the scene of that devastation and straight into the blast zone.

Dry - Lots of leaves and pine needles on the forested trail. Great time of year to ride this trail with the fall colors.

This was the hardest mtn bike ride I've ever done, but also the most rewarding. It took 6 hrs for my husband and I to do because I'm overweight so I had to stop after every incline. I did do a lot of walking on the steeper sections since I couldn't make it up them. Even though I had a difficult time on the way up, all of the frustration melted away once we were up by the mtn. What an experience! Apr 2, 2017
