The Castle Crest Trail is located on East Rim Drive near the Steel Visitor Center. It is a half mile loop and fairly flat. A color trail guide is available for purchase at the trailhead. They are provided by the Crater Lake Natural History Association. The trail crosses a stream and can be wet. Be prepared for mosquitoes!

Take the loop counter-clockwise and you will quickly come upon a hillside with streams flowing down it, covered with a breath-taking display of wildflowers, including: purple and white lupine, pink Lewis monkeyflower, yellow flowers and more. Moving on to the drier side of the trail were skyrocket gilia. The park guide notes that abundant wildflowers can be seen mid-July to mid-August. Photos below are from late July 2012. It was the largest wildflower display in the park. Definitely a must do on your visit to Crater Lake. Meadow with stream and wildflowers, Crater Lake Castle Crest Trail
