A beautiful easy hike to the shore of Spirit Lake. No bathroom at this trailhead but there are bathrooms at other viewpoints along 99. We went on a cloudy day so no view across the lake but the fog added a mysterious and cooling layer to our hike. There is a small steep section going down near the lake, watch your footing as the trail is sandy with gravels. It's an amazing experience being there looking at all the floating logs from the eruption.
