Mount Rainier National Park encompasses the namesake peak: a 14,000-foot volcanic giant that looms large over Washington’s pacific northwest. Climbing Mt Rainier is a career goal for many Cascade Range peak-baggers, but exploring the park’s many miles of trail equally popular among the less alpine-inclined. If you are passing through Seattle, set aside a day for some Mt Rainier hikes. We recommend trying a section of the Wonderland Trail. If you do want to make it to the top of the mountain itself, plan accordingly; summit attempts can take up to 6 days to complete.
