This section begins at the Bridge of the Gods (elev. 180′), on the Columbia River and ends at Monument 78 on the Canadian border (elev. 4,240′). An additional seven miles were added beyond the border by the Canadian government to provide access to Highway 3 in British Columbia’s Manning Provincial Park (elev. 3,800′).
Starting with a lengthy climb out of the Columbia River Gorge, the trail eventually reaches the crest near the Indian Heaven Wilderness, a lake-filled land abounding with huckleberries. Next, it rounds the base of mammoth Mount Adams (elev. 12,276′). Just north lies the dramatically rugged Goat Rocks Wilderness and a traverse of the Packwood Glacier.
The trail crosses Highway 12 at White Pass before encountering dozens of lakes in the William O. Douglas Wilderness. Between White Pass and Highway 410 at Chinook Pass, the trail skirts many lakes as it approaches the towering monarch of the Cascades, Mount Rainier (elev. 14,410′). From Chinook Pass, the trail has an easy, rapid run to Interstate 90 at Snoqualmie Pass. This stretch presents many private land clearcuts that offer little cover from the often present rain.
