Camassia Natural Area
A rocky basalt plateau in West Linn preserving an ancient plant community — 300+ species, camas lily fields, and Oregon white oak woodland on geology shaped by the Missoula Floods.
About the site
Camassia Natural Area is a 25-acre preserve managed by The Nature Conservancy — one of Oregon's best wildflower viewing locations and one of the last intact camas and Oregon white oak meadow ecosystems in the Willamette Valley. The rocky basalt outcrops were exposed by the catastrophic Bretz Floods roughly 12,000–19,000 years ago and have never been tilled, preserving an ancient plant community with over 300 species.
This is more of a natural area to visit than an organized festival — no entry fee, no ticketing, just a walk-in preserve. Volunteer naturalists from The Nature Conservancy are on-site on spring weekends during peak bloom.
What to expect
Purple and blue camas lily fields across a rocky plateau, framed by Oregon white oak and aspen. Volunteer naturalists on-site spring weekends to orient visitors and identify rare species — blue-eyed Mary, rosy plectritis, white rock larkspur, and white oak at the edge of their range.
Wildlife including osprey, hairy woodpeckers, spotted towhees, amphibians, and deer. Popular on spring weekends — arrive early or visit on weekdays to avoid crowds. The preserve is small; the experience is intimate and unhurried.
Preserve rules
Stay on marked trails; walk single file on narrow paths. No dogs, drones, or motorized vehicles. No plant collection. No camping. Groups of 10 or more should contact The Nature Conservancy Oregon office in advance.
