Mount Saint Helens Summit via Monitor Ridge Trail

Route Description for Mount Saint Helens Summit via Monitor Ridge Trail

Mount Saint Helens is a simply gorgeous trek and should be on the bucket list of any hiker fit enough to do it. Keep in mind, this hike is more accessible than you might think! The Monitor Ridge approach requires no technical climbing. It does require a solid physical effort, preparation for the conditions, and attention to the weather. All that being done, you can enjoy the stellar views from this active volcano.

The best time to complete this hike is in the summer when there is minimal snow on the trail. Still, bring microspikes, poles, and good boots. The footing can be loose and rocky. You’ll also want to do your best to plan for a day with minimal wind and clear weather in the forecast. The summit is almost always windy, but it can get brutal. Goggles aren’t a bad idea if you want to actually be able to enjoy your views in the gusts.

This route begins from the Climber’s Bivouac Trailhead. You’ll take the first 3.4 km on Ptarmigan Trail, which rises 305 m through the woods and into alpine meadows. Cross through the junction with Loowit Trail. You’ll need your climber’s permit to ascend past this point to Monitor Ridge Trail, so make sure you get one prior to the hike.

Entering the clearing past the creek, you’ll see the Green Knoll in front of you. Now on Monitor Ridge Trail, you’ll soon encounter a selection that requires scrambling over boulders as the trail peters out. This isn’t exceedingly difficult and is a bit easier on the way up than it is on the way down.

Note: This boulder field is covered in ash pumice. Ash pumice can shred your skin in a fall, so we highly recommend packing a pair of gloves and hiking carefully.

The last portion of the trail takes you up 305 m vertical through the rocks and ash to the crater rim. It’s a real grind, but make sure you take a moment to appreciate the views as you go.

Atop the summit, you’ll stand in awe at the massive crater with the glacier forming a horseshoe around the expanding dome. Look out towards Mount Hoof, Mount Adams, and Mount Rainier.

Once you’re ready, the descent begins. Poles will be essential on the way down, as will a slow pace through the boulder field.
