The Skyline Loop is a moderate-to-challenging, approximately 5.5-mile loop with about 1,700 feet of elevation gain, making it best suited for active beginners who are comfortable with sustained climbing and intermediate or experienced hikers. Beginning at Paradise, the trail climbs through some of Mount Rainier’s most spectacular high-country scenery, with sweeping mountain views, seasonal wildflower meadows, cascading streams, glaciers, and frequent opportunities to spot wildlife. On clear days, the massive slopes of Mount Rainier dominate the landscape while distant Cascade peaks stretch across the horizon. With significant elevation packed into a relatively short distance, this hike delivers a solid workout—but the extraordinary scenery makes it one of the most rewarding hiking experiences in the park.The Skyline Loop is a moderate-to-challenging, approximately 5.5-mile loop with about 1,700 feet of elevation gain, making it best suited for active beginners who are comfortable with sustained climbing and intermediate or experienced hikers.
