Hey, if you are still out there...Try Mildred Lakes up in the Olympic National Forest. The hike is tough/steep (4- 8 Hrs off grid). The lake has tons of fish with berries on the trails depending on when you go. It is summer time so you might find more people there, but most of them are on a day trip. It is very hard hike / climb, trial is marked but not always clearly.
The best hike / camp out we ever had.
