From atop its summit, the highest peak in the Cascade Range reveals a chain of volcanoes—St. Helens, Adams, Baker, Glacier Peak and Hood—stretching southward. Rainier is considered a beginner trek. But don't let this label, and its easy accessibility (just 50 miles southeast of Seattle) fool you into thinking it's without challenge. The mountain hums almost daily with high-frequency earthquakes, and it's riddled with crevasses.
