Northern Loop: Carbon River to Windy Gap

This section of the Northern Loop trail takes you through some of Rainier's most rugged and least-visited backcountry. Starting from the Carbon River area — the park's rainforest corner — you'll push through dense old-growth forest draped in moss before the trail begins its relentless climb toward Windy Gap. The lower stretches feel almost Pacific Northwest cliche: towering Douglas fir, sword ferns brushing your shins, creek crossings that demand attention. As you gain elevation, the forest thins and the views crack open — Rainier's north face looms with a rawness you don't get from the postcard-perfect Paradise side. Windy Gap earns its name; expect exposed alpine terrain with sweeping views into the backcountry. This is a trail for hikers who want to earn their solitude and don't mind route-finding through sections that see minimal maintenance.
