Now accessible only via the Blue Lake Trailhead (or a thru-hike), this bridge offers safe passage across Sheep Canyon and its riotous creek, both of which cut across the western flank of Mount St. Helens. Leave yourself a little time to hike upstream and see a waterfall.

The South Fork Toutle River is a reliable water source along the Loowit Trail. There are also spots to pitch your tent at the south side of the river. A rope will help you to climb over the loose rock down and up the river bank.

This is where the Ptarmigan Trail meets with the Loowit Trail and Monitor Ridge. If you plan to summit Mount Saint Helens, you continue along the rough Monitor Ridge. Keep in mind that you need a permit to do so. The Loowit Trail, however, circumfences Mount Saint Helens and leads you to the blast zone. It is 30 miles long, so it can be a great multi-day adventure. There is no permit needed to complete the Loowit Trail.

Most people will know the name of Mount St. Helens due to the massive eruption that happened in May 1980. In that event, the top of the mountain was blasted away by the pressure that was released instantly and the north side collapsed with a gigantic landslide. Today, the volcano is still mildly active. You can see steam coming out of the crater and timelapse videos show the evolution of new cones over the years. A steep trail will lead you to the rim with some difficult terrain, the true summit is another 0.4 miles to the west. For summiting Mount St. Helens, you need to obtain a permit year round.
