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!


O’Brien Creek near the trailhead.
It seemed like all of the climbs this weekend had been steep.
After two warm sunny days this hike finally felt like Fall.
As I approached this footbridge I noticed a yellow jacket fly into the big hole along the right side of the trail. A quick peak in revealed a busy nest so we wound up bushwacking uphill and around it hopping onto the bridge at the edge of the marsh ahead.
A nice newer looking sign at the upper trailhead.




There were a few really big trees in the forest along the trail.
Grayback Mountain from the trail.
The trail crossing O’Brien Creek.
The junction with the spur trail to the snow shelter. It took me far too long to realize that the sign was upside down. I couldn’t figure out why it thought the Boundary Trail was to the left, after looking at it a few more times it dawned on me that the words were upside down.
Ah ha! It wouldn’t stay this way but it sure made more sense.





There used to be a cabin out in the meadows and now there is a snow gauge and a campsite which may be where the voices were coming from.
We took a quick peak inside the shelter where some of the backpacker’s stuff was.
It was steep going down too.
Trail pointer near the upper trailhead marking the continuation of the O’Brien Creek Trail to the lower trailhead.
We always enjoy seeing madrones on our hikes in Southern Oregon.

One more steep drop to the lower trailhead.


The forest is recovering from the 2002 Biscuit Fire.
To the left was the Babyfoot Lake Rim Trail. Sullivan’s longer option here include following this trail 0.9-miles to a viewpoint above the lake. Given the fog that seemed pointless, and it also looked like that trail was in need of some maintenance.
A small stream with crystal clear water along the trail.
My nemesis, the varied thrush.
Near the lake the trail passes this rock outcrop which is a viewpoint without the fog.
Some of the trees around the lake survived the 2002 fire.


I of course had to head out onto the viewpoint given the rapidly changing conditions.


The patterns on this snag caught my eye.
The trailhead on the ridge ahead.

There is a large turnaround/parking area at the end of Forest Road 041 which serves as the trailhead. The final 500 meters of the road are rough so high clearance vehicles are recommended.
A pink flag marked the start of the trail just up the road from the turnaround.
The trailhead from the Tanner Lakes Trail.
A few trees survived the fire around the lakes.

The trail briefly left the fire scar altogether near the Fehley Gulch junction.

Scarlet gilia
One of two checker-mallow blossoms I spotted. The other was much nicer looking but it was downhill and I was too lazy to go down to get a good photo.
This trail was really steep at times.
Almost to the ridge.
The trail became pretty faint on the ridge.
More steep climbing.
Looking back down over the use trail.
From right to left – Grayback Mountain, Lake Mountain, and Mount Elijah (with lots of other peaks).

It’s in the shadow but the runoff channel cut across the road here creating a decent sized divot.
Another rocky section of the road.

The pointer is a trap!
This looked like as clear a spot as any.
Looking up the Bolan Lake Trail.
My guess is the rock on the log was where the trail used to begin but the log had been a bit too large to climb over.
Faint tread was all that was left in most places.
The Bolan Lake Trail to the left.
Sometimes the tread just disappeared.
Lake Mountain, Grayback Mountain, Craggy Mountain, and Swan Mountain.
Momentary tread.
Just about 500′ below the ridge there was a large downed tree which required some side-hilling to drop below and then climb steeply back up to the trail.
I got back to the trail to find more debris covering it.
Final pitch to the ridge.
Bolan Mountain from the ridge.
The trail descended slightly on the far side of the ridge to the junction.
I assume the downed post and small pile of rocks marked the junction with the mile long Kings Saddle Trail.
The Bolan Lake Trail (I think) at the junction.
I might be on trail.
I was sure I was on the trail here.
Mountain bluebird wondering what I was thinking.
Now I was just going uphill.
No idea where I was supposed to be at this point.
The rocky point that the GPS labeled as Bolan Mountain.
I got this far before realizing I was heading to the wrong spot.
At least from here I could see the road heading up to the former lookout site through the burned trees.
Not sure if the outhouse (above to the left) survived the fire or is new.
Stone steps to the former lookout site.

There are a couple of the red Indian warrior behind and to the right of the trail marker.

Based on the trees it looked like the thunderstorm provided some fresh snow at higher elevations.

There were a couple of nice benches along the trails here.
