The Picnic Vista offers unique playground equipment, like a zipline and wading pool, as well as large fields for sports. Over six miles of trail can be accessed from our trailheads in the park and along the entrance road. For more information, visit our official website . Recreation Many families come to Mud Mountain Dam Park to have a picnic and enjoy the outdoor recreation features. A two foot deep wading pool allows children and parents to stay cool in the summer heat, while others play on playground equipment that is hard to find anywhere else! For visitors that are more nature oriented, go for a self-led hike on the Rim and River Trails to catch a glimpse of a Bald Eagle flying overhead or Elk browsing in the forest. Mountain bikers and hikers are welcome to use any of the trails, but horseback riders should limit their rides to the River Trail at the current time.
