Several years ago we set a goal for ourselves to hike all 500 featured hikes in William L. Sullivan’s “100 Hikes…” series of guidebooks (post). In 2020 we completed the first of these books covering the Central Oregon Cascades (post). We followed that up by completing a pair of books in 2021 starting with Sullivan’s “100 Hikes/Travel Guide Oregon Coast and Coast Range” 3rd edition (post) followed up by “100 HIkes/Travel Guide Northwest Oregon & Southwest Washington” 4th edition (post).
Generally speaking in order to check a hike off our list we need to have hiked a substantial portion of Sullivan’s described hike or visited the main attraction(s) he identifies for the hike. For 66 of the hikes we followed the books described route. For the other 34 hikes various factors contributed to us not completing all of each featured hike. For some we started at a different trailhead, others had portions of trail(s) closed when we visited, and several had longer options that would have required multiple days to complete. In some other cases we did slightly different routes, sometimes by accident.
The area covered by Sullivan in this book, as the title suggests includes parts of Southern Oregon and Northern California. It contains his southernmost featured hike, Caribou Lakes. In general the area covered in Oregon begins just North of Roseburg extending East to Highway 97 (with the exception being Klamath Falls which is included in his Eastern Oregon book), South to California, and West to Marial on the Rogue River. In California the area extends south to the Trinity Alps Wilderness, West to the Siskiyou Wilderness, and East to the Mount Shasta Wilderness.


In addition to the three wilderness areas in California mentioned above the featured hikes included visits to the Marble Mountain, Castle Crags, Russian, and Red Buttes Wilderness areas in California. Wilderness areas in Oregon included the Red Buttes (OR & CA share this wilderness), Kalmiopsis, Wild Rogue, Soda Mountain, Mountain Lakes, Sky Lakes, Rogue-Umpqua Divide, Boulder Creek, and Mt. Thielsen.
In addition to the 15 designated wilderness areas there were hikes in two National Monuments – Oregon Caves & Cascade-Siskiyou, and Crater Lake National Park.

In our minds this was by far the most challenging area to finish even though we did so before completing Eastern Oregon. The difficulty with Eastern Oregon mostly revolves around distance from Salem and the size of the area covered. The Southern Oregon-Northern California area is smaller and the hikes not as far away, but it involved a lot of trails that frankly don’t see the level of maintenance that most of the other areas receive. While we’ve encountered rough trails, all over poison oak is much more prevalent down south which doesn’t invite pushing through overgrown tread or bushwacking around obstacles. This area has also been hit harder by fires over the last couple of decades leaving extra work to reopen them as well as remove additional blowdown as the dead trees fall over. When the conditions were good though the scenery and diverse plant and wildlife made for some spectacular hikes. There are many that we’d love to do again and several non-featured hikes that we have in our future plans, so we aren’t done with area yet. Happy Trails!
