Wildflowers are found in rotational bloom as soon as the snow melts and up to the fall frosts when the fall colors begin. Popular spots for viewing the widest range of wildflowers include Trillium Lake Loop Trail and Summit Meadow and trails above the timberline, especially the Timberline Trail/Pacific Crest Trail east and west of Timberline Lodge, Paradise Park and Elk Meadows (generally in July and August).
