Waldo Weekend Campout - August 28-30

Save the date for Waldo Lake fun at the Shadow Bay Campground: camping, hiking, biking, kayaking, canoeing, swimming, stargazing, lakeside relaxing, and absorbing all that fresh oxygen, hosted by the Juniper Group of the Oregon Sierra Club. Enjoy hikes planned ranging from easy to difficult so everyone can explore this magnificent watershed. Bring your tent or camper, share a favorite dish at Saturday night's pot luck around the campfire, and learn about the progress of our Keep Waldo Wild conservation campaign. Expect to share a campsite with other campers. Families with children are welcome, as are a limited number of dogs. For a more complete description of the campout, visit the Juniper Group website, where you will also find the Waldo Weekend Campout Reservation Form.
