Pumice Butte is a dispersed camping area along the Loowit trail that circles Mt St Helens. If you're starting from Ape Canyon or June lake Pumice Butte is a great place to camp for your first night (about 5-6 miles in respectively) There is some tree cover here before you enter the Plains of Abraham that works for shade or a wind break - you mind need both.

There is not much water along the trail, but we found a small spring about 1 mile past Pumice Butte
