I began this hike not knowing how much of a trail would exist past the old six mile camp, and every account I could come across said there was no trail up Bachelor creek. With this in mind, we cruised through the first six miles of train up Downey Creek (thank you WTA!!) which were logged out and almost completely brushed. The official trail ends just past the log bridge crossing Bachelor Creek, and there is a nice place to camp if you are so inclined.
The next several miles were a different story. A path does exist, and by following the cairns we found the old trail fairly easily. It winds its way on the north side of Bachelor Creek for a few miles, and there were long stretches where the trail is in good shape. However, many spots were overgrown with huckleberry or vine maple, creating a nice little tunnel for a rabbit but I couldn't even see my feet! Still, by looking for the trail on the ground, we were ably to work our way up the creek. In a few places we lost the trail and had to backtrack to regain it, but never more than a dozen feet. When we went up, there were bits of flagging marking the trail, but they mainly served as confirmation that we were on the right path.
The path eventually made it to a log crossing, we later heard it is at about 4000' elevation but the crossing was well marked with flagging on either end of the creek. The south side was more overgrown than the north, often winding through slide alder and through overgrown meadows. The occasional flagging was a help, but the path was still discernible under the brush. There is another campsite a mile or more from the crossing, a good place to stop for the night.
The trail levels out a bit here, and was muddy and marshy in spots but nothing like we expected. When the path begins to climb out of the meadows there are more blowdowns, some of which were marked at the ends. The trail here was harder to follow, especially where many trees covered a section. There is a final scamper straight up an old slide, and this section is dusty and eroding quickly. The occasional flagging or cairn still points the way through to the end...
Honestly, all the work we had to do to get up to the top hardly seemed worth it. We camped a night at Mule lake to sample vegetation on the ridge north of Bachelor creek but decided to pack up and head to Cub lake for a night. The views of this lake from the top, the waterfall near the lake and the little meadow between Cub and Itswoot Lakes made up for the bushwhacking and more. It's a hard trip for an alpine lake, most people take this path to climb Spire or Dome, of to come out of the Ptarmigan traverse, but I think it is a worthy destination on its own, and the lack of a true trail should discourage most. Don't try it unless you have some decent route finding skills!! Maybe WTA can work on the upper trail, now that Downey Creek is in good shape?? :-)
