From downtown, Nordic Dr heads north on a scenic route that ends at Sandy Beach Recreation Area, a beautiful day-use area 2 miles from downtown. There are 2000-year-old Tlingit fish traps snaking the mudflats and a rock with petroglyphs carved on it. Both the traps and the carvings are hard to spot, but the Petersburg Ranger District organizes guided interpretive walks to them during the summer here. Call for times.
