Looking to avoid the chaos of post-Huskies traffic, I went for an afternoon hike to Lake Janus and beyond. My plan was simply to hike for about two and a half hours and turn around. This got me to the pleasant meadow mentioned in the guide but not to the Glasses Lake viewpoint, 12.3 miles in total.
Although the parking lot was overflowing when I arrived a little after 1, the trail was never all that crowded. Both directions of the PCT lead to popular destinations and I suspect that many people start backpacking trips here on Friday afternoon. Of the 20 or so people I saw on the trail, at least five of them were PCT thru-hikers (you can tell by the beards). It's that time of year.
The steepest part of the hike is probably the first half mile of the Smithbrook Trail. The PCT has ups and downs but the grade is never too tough in this region. Furthermore, most of the climbing is in the woods. Erosion is a problem in a few places between Union Gap and Lake Janus. It's also pretty brushy in a few places. I don't know if I'd feel comfortable hiking that part of the trail on a rainy day. North of the lake, the trail is briefly a bit of a slog before becoming relatively level as it crests the ridge. Do keep in mind that you have to regain all of the elevation you lose between Union Gap and the lake on the way back.
This isn't a great hike for fall colors, but the meadows have already started to pick up some red highlights. The pikas and squirrels were very busy collecting food for winter. If there were any huckleberries along the trail, somebody got to all of them before I did.
By far the worst part of the hike is driving to and from the trailhead. Highway 2 seems to be particularly popular with people who like to drive really slowly around corners and really quickly on the straight stretches. More notable is the fact that there is currently construction on Highway 522 in Monroe and on Highway 2 just east of the pass. Drive to Leavenworth this weekend and you may get a free butt massage out of the deal. The Smithbrook Road itself is bumpy but not otherwise a difficult drive. Some parts appear to have taken a beating in a recent rainstorm, but the parking lot was full of small cars. Even in my Mazda 3, it took less than 15 minutes to drive from the highway to the trailhead. Don't fear the dirt road.
Overall, Lake Janus is a nice destination but hiking to Grizzly Peak's probably not the best use of your time unless you do it as part of an overnight trip. There are many other trails in this area offering superior views and scenic meadows. Admittedly, most of the alternatives are a whole lot further from the highway.
