At the Windy Ridge parking lot there are several trails that begin here. This Pumice Plains trail begins at a gated (road closed) entrance, furthest from the restroom. There is a steep staircase, near the restroom, that ascends up to a lookout above Spirit Lake. This is not the Pumice Plains trail.
The trail directions (WTA) state that the beginning "descends" this is incorrect. It is an ascend up an old logging road about a mile. Beautiful views of snow covered Mount Adams in the distance. At about a mile the trail then descends, the road ends at a junction for Loowitt Falls/Pumice Plains (Trueman). Take a right here for the Pumice Plains trail. Not before taking in the majestic views of Mount Saint Helens.
At about 2.3 miles in there is a dry creek bed that must be crossed. After that a small stream crossing that was easily passable. Spirit lake and its surrounding mountains come into view. After about 3 miles the trail is washed out by a small stream, which is easily passable; however finding the original trail afterwards was a challenge. After crossing the stream the trail is towards Mount Saint Helens, not Spirit Lake. We hiked in about 5.5 miles. At this viewpoint you can see Johnston Ridge Observatory and Loowitt Falls from a distance. This trail does not take you to the lake shore, but you get pretty close.
Amazing wildflowers in bloom. Lots of ash, pumice, lava rocks, and sand. It was a very hot hike with 85 degree temperatures, but the wind cooled us down Hence the name "Windy Ridge." We opted to apply sunscreen prior to leaving the car. Unfortunately, the sweat, ash, and sand removed most of it. Needless to say we have matching sunburns. There were no bugs on the trail, but as soon as we copped a squat on a lava rock to have lunch the ants attempted to make off with our meal. Lots of birds flying about and a deer was spotted atop a bluff while on the logging road. Observed bear scant and elk droppings on the trail, but did not see any. Even though it has been 35 years since the eruption, this trail appeared more like a dessert than a PNW trail. This was a different kind of hike than we are used to, but it was gorgeous!
