Path: Sunrise Visitor Center - NE to Sourdough Ridge (0.3) - follow Sourdough Ridge / Fremont Lookout trail to Frozen Lake (1.5) - follow Wonderland Trail back to Sunrise Visitor Center, skipping shadow lake (1.4).
The flowers are beginning to bloom, but full bloom is not for another two weeks. There were no bugs until near frozen lake.
This 3-mile-loop is an easy half day hike with outstanding scenery, fit for families. You remain above the treeline for most of the hike. There are only two relative steep sections on this loop, the initial hike up to Sourdough Ridge and when you first step on Wonderland trail from Frozen Lake.
Sourdough Ridge has an expansive unobstructed view of Mt Rainier. There are still patches of snow on the trail, covering about 50 ft of trail. The excellent view continues on the flat section of Fremont Lookout Trail to Frozen Lake. Return route from Frozen Lake is the toughest part, as soon as you step onto Wonderland Trail, there are two big snow patches, each covering about 200? feet of trail, on relative steep descent.
