The tent sites at Alosa may be primitive, but they're supremely serene as well. The campground is located on a forested patch situated above the river. There are dirt paths to the restrooms, but not much else, other than peace and quiet (and insects) in the evening. Bring everything you need for cooking and sleeping, and bear-proof your grub.
