Zigzag Ranger District spans parts of the South and West side of Mt Hood. The District is comprised of 250,000 acres and is located near a metropolitan area of over a million residents. The district manages one of the largest recreation programs including 550 summer homes, 30 developed campgrounds, 3 ski areas including Timberline Lodge (Timberline Lodge has nearly 2 million visitors a year, and is one of only three National Historic Landmarks in the Forest Service System), many special use permits, over 300 miles of trails, and 2 wilderness areas. The district also manages the Bull Run Watershed cooperatively with the City of Portland, which supplies drinking water to the Portland metropolitan area. The compound of the Ranger District is historic, constructed in the 1930’s by the CCC. Many of the original buildings remain.
