We started in a very secluded parking lot at the end of FS600 and started our adventure over an Olympic Mountain pass to find Satsop Lakes. The parking lot is in the headwaters of the Skokomish River that drains into the Hood Canal, while the water at Satsop Lakes drains into the Chehalis River, and then the Pacific Ocean: pretty neat. The trailhead isn't marked, but is well maintained. For the first section, we climbed through old stands of firs and meadows of huckleberries. The section was pretty much the same, but we were going downhill. There wasn't any flowing water after the first mile until you get to the first lake. Also, there were a fair number of biting insects, but nothing too heinous. We didn't see anyong else, hear any cars, or even an airplane. That's a pretty tough find for western washington on a weekend!
The are no signs, save a random FS "equal employement" laminate a few yards down the trail. It looks like there's been solid trailcrew work for the first mile or so, then it gets more overgrown. It's pretty easy to follow, though. I think the trail follows a different route than what's shown on the map on the second section, after you cross the pass.
