My wife, grandaughter, and friends camped at Ten Mile Campground and thoroughly enjoyed the small, pretty creek running through a nice copse of pine, spruce, and hemlock trees. Be prepared to walk along the highway, but there is plenty of room on the shoulder. Ten Mile is one of our favorite places.
Cache is near the highway, but hidden in the trees, so you shouldn't have to worry about muggles. FTF may choose between a LED necklace, a pretty rock, a magical fairy unicorn, a fridge magnet, marble or bracelet.
