Welcome to Klamath Basin National Wildlife Refuges
Of the six stunning national wildlife refuges in this group, Tule Lake and Clear Lake refuges are wholly within California, Lower Klamath refuge straddles the California–Oregon border, and the Upper Klamath, Klamath Marsh and Bear Valley refuges are across the border in Oregon. Bear Valley and Clear Lake (not to be confused with the Clear Lake just east of Ukiah) are closed to the public to protect their delicate habitats, but the rest are open during daylight hours.
These refuges provide habitats for a stunning array of birds migrating along the Pacific Flyway. Some stop over only briefly; others stay longer to mate, make nests and raise their young. The refuges are always packed with birds, but during the spring and fall migrations, populations can rise into the hundreds of thousands.
