Back in 2016 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). Southern Oregon & Northern California was completed in 2023 leaving us with Eastern Oregon.
In 2023 we pivoted from the 3rd edition of Sullivan’s “100 Hikes/Travel Guide Eastern Oregon” to his renamed 2022 1st edition “100 Hikes Eastern Oregon” book. This was to avoid needing to make the tedious drive on horrible roads to Dug Bar in Hells Canyon which had been replaced as a featured hike in the newer edition.
The criteria for checking a hike off our list is to hike a portion of Sullivan’s described hike or, at least visit the main attraction(s) he identifies for the hike. For 67 of the hikes we completed the books described route. For the other 33 hikes various factors contributed to us not completing every option 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 additional options that we did not do.
Of the five regions Sullivan breaks his guidebooks into, the Eastern Oregon region is the largest and most diverse. The area covered in this book includes hikes in Oregon east of the Deschutes River in Central Oregon and from Klamath Falls (western most hike) east to the Idaho border. There is however one hike in Washington west of the Deschutes across the Columbia River from The Dalles, OR. It also includes one short option in Idaho (eastern most), one featured hike in California (southern most) making it his only book with hikes in more than two different States. The northern most hike is not the one in Washington. That honor belongs to the Wenaha River near Troy in NE Oregon.

The hikes involved several wilderness areas: Oregon Badlands, Mill Creek, Spring Basin, Strawberry Mountain, North Fork John Day, North Fork Umatilla, Wenaha-Tucannon, Eagle Cap, Hells Canyon, Monument Rock, and Steens Mountain. Missing from this list are the Black Canyon (post) and Gearhart Mountain (post) wilderness areas which had featured hikes in earlier versions of Sullivan’s book that we’d completed, but were removed in the 2022 edition due to wildfire damage.
In addition to the 11 designated wilderness areas there were hikes in two National Monuments, the John Day Fossil Beds National Monument in Oregon and the Lava Beds National Monument in California, and one National Volcanic Monument, the Newberry National Volcanic Monument.

*The Juniper Hills Preserve is owned by the Nature Conservancy and had been closed to public entry in 2023, so we were unable to hike the trails. We parked and walked to the gates to take photos. If they ever reopen it to the public we will go back.
Completing our featured hike goals provided a sense of relief. While we thoroughly enjoyed all of the hikes, and the Wallowa Mountains became our favorite destination in Oregon, we had begun to put pressure on ourselves to finish. That pressure had begun following the September 2020 wildfires that ravaged parts of the Central Cascades and left many trails closed for years. We had just finished the featured hikes in that area earlier that year and realized how close we’d come to having to put our goal on hold. In the grand scheme of things reaching 500 featured hikes is irrelevant but having worked on it for several years it was something we didn’t want to abandon. We will gig deeper into that in a later post covering finishing the 500, but it’s nice to have the urgency to get to specific places removed.
Setting the goal did provide us with an excuse to visit parts of Oregon that we’d never seen before. While we were checking off the 100 featured hikes we stopped at over three dozen additional spots including eight previously featured hikes. There are still numerous trails left for us to explore so we will almost certainly be heading back to Eastern Oregon from time to time to see new sights and possibly revisit some familiar ones. Happy Trails!

The start of the loop trail.
We like interpretive signs like this where we can see with our own eyes what is being described.
This one helped with identifying the different lakes plus provided the history.
Another of our favorites are the ones that identify the various hills and peaks.
We worked really hard on spotting some big horn sheep on this trip to no avail. There was so much space that they could be in it was like looking for a needle in a haystack.
It’s not visible in this photo but there were dry rocks close enough on the far side to simply step over the water onto. The wet rock would have been very slippery and certainly dangerous.












The scramble route is at the base of the cliff to the right.
