My partner and I headed out for a sunny day hike to Lost Lake with a little extension up to Noble Knob. The (paved!) parking lot for Lost Lake was full by the time we arrived around 10 a.m. but a lot of folks were leaving (many backpackers who had spent the night on Friday) so finding a spot was no problem. The first few miles of trail were pretty bustling but it got quieter the farther out we made it. Plenty of water to be found along the entirety of the route.

A bridge is washed out a few miles in and there are two ways to get across the river — a shorter route via a small log jam with a hand rope or a slightly longer route over a massive fallen tree that serves as a makeshift bridge. We tried out both routes and I found the makeshift bridge to be easier (or at least, it was easier to keep my feet dry).

It was a beautiful Saturday and campsites around Lost Lake were at a premium. We stopped by the shores to have lunch and saw many groups milling around in search of a spot. Several tents were in... questionable locations.

The trail up from Lost Lake to Noble Knob gains a lot of elevation (relative to the fairly flat path to Lost Lake) and has a few easy-to-cross snow patches lingering on it. There are a few trees down but nothing too bad. We stopped a bit short of the actual Knob (~5400 feet) at a nice viewpoint and then headed back.

As an out-and-back day hike the trip ended up being around 14 miles but with a bit more time, it would have been great to loop back by connecting Dalles Ridge & Echo Lake — next time!
