primary visitor service in this section of the park is the William G.
Steel Information Center (open year-round). Information, backcountry
permits, exhibits, maps and publication sales, an audio-visual program,
and first aid can be obtained at the center. The other developments in
Munson Valley are for park support personnel.
If you approach Munson Valley from the north
(accessible only from late June to October), the easterly portion of the
Rim Drive is a left-hand turn just past the Steel Information
Center. Continuing straight ahead (south) takes you to Mazama and the
Annie Spring Entrance Station. If you approach Munson Valley from the
south, you encounter the junction with the Rim Drive. Proceeding
north-west, you begin the clock-wise portion of the Rim Drive, and access
to the Rim Village. Turning east takes you around Crater Lake in a
counter-clockwise direction and is the quickest route to The Pinnacles
section of the park.
A short distance (east) of this road junction on
the Rim Drive is the delightful Castle Crest Wildflower Trail.
While this is a short .4-mile loop trail, the tread is uneven and is not
suitable for wheelchairs. When flowers are in bloom the profusion of
colors is spectacular. The trail passes from forest, to wet meadows,
crosses a tributary of Munson Creek, and finally passes a small dry slope
exposing the visitor to a wide assortment of Northwest wildflowers.
