It was almost $60 this spring for car and driver. It's probably double that by now.
Camping, cabins and a I believe there is a hotel at Beaver.
Why haven't you been up there yet? It's the only piece of the OK still tourist free.
When I go back to the Island I'd be pulling the 5th Wheel, so will probably need 3 wallets. I checked out the lakes on Yahoo maps, found Oyama (I was already aware of it) and Streak but couldn't find Beaver or Dee. Looks like good road into Oyama Lake, are all the other ones accessable by decent road (don't want to tear an axle off my new truck) Where are Beaver and Dee compared to Streak?
