Cooper Lake WA.
Very remote woodsy area around the lake. Pristine waters, state fish stocked lake, bring drinking water. The lake does not have a road going around it, but the fire roads do have trail heads for backpacking. There is camping on the other side of the lake only excess by boat. Well I guess a helicopter would work. There are horse camps at the end of the fire road with a cul-de-sac to turn around and head back out. Lots of boon-dockers off the forest roads. A boat launch is available but motors are not allowed on the lake.
