Are you wanting to hunt close to the Dosewallips? You can hunt along the road past the washout up to the park boundary. I see sign along the road. Usually see a few grouse too. But there are nearby areas like Duckabush or Big Quilcene that aren't all that far. East side of the Olympics are pretty steep and probably be pretty warm out on Labor Day. Usually the low, cool, shady spots near food are good places to look.
