Tucked away in a nearly-forgotten corner of Deschutes National Forest, just an hour’s drive west from Culver, the hike along the Lower Metolius River follows a long-abandoned road for 3 miles over riverside terraces and through stands of old-growth incense cedars and firs. The star attraction here, though, is the local population of ospreys, a species of fish hawk that nests in the top of large snags near the river. Hikers during summer will be treated to the aerial displays of these soaring raptors, overhead and around their large stick nests.

Once a shallow 2,000-acre lake, which was filled by volcanic ash during the eruption of Mt. Mazama 7,700 years ago, Big Marsh today is one of the largest, high-elevation wetland/marshes in the nation. A half-hour drive west of Highway 97 from Crescent, it’s a one-of-a-kind resource supporting a wide diversity of Central Oregon wildlife — from elk, to river otters, to sandhill cranes — plus the largest population of threatened spotted frogs in Oregon. A 2.4-mile cross-country ramble invites visitors to explore this natural wonder.

The original railroad surveys of the Deschutes River Canyon, conducted in 1855 by Army engineers, concluded that “the Deschutes Valley is mostly a barren region…separated from the rest of the world by almost impassable barriers.” In fact, at the turn of the century, Central Oregon was the largest territory in the U.S. without a railroad. Only in the early 1900s, when its wealth of ponderosa pine was recognized by commercial interests, was serious rail construction begun south from the Columbia up the Deschutes River. Hikers today can follow a section of this now abandoned rail bed for many miles, with spectacular river and canyon views.

Sometimes the distinctive natural landforms of a place combine with centuries of human activity to create an exceptional mix of geography and history. The Klamath Marsh Narrows is such a place. This three-quarter mile crossing, in the midst of 65 square miles of sprawling marshland, has been used by Native Americans for millennia, by the John C. Fremont expedition in 1843, and by travelers down to the present day. It’s one of the best birding spots in Central Oregon, and hikers can follow in Fremont’s footsteps along the edge of the grasslands, enjoying solitude and sweeping Cascade mountain views.
