Deer Mountain, Mountain summit in Ketchikan Gateway Borough, US.

Deer Mountain is a 3,001.97-foot (915 m) peak in Tongass National Forest that rises behind downtown Ketchikan. The Deer Mountain National Recreation Trail climbs 2,600 feet (790 m) over 2.75 miles (4.43 km) from its trailhead in Ketchikan, crossing temperate rainforest, muskeg and alpine meadows on the way to the summit.

Local residents created trails on the mountain in the early 1900s to connect different parts of Ketchikan. These early paths were later expanded into the hiking routes that visitors use today.

The mountain's name comes from the deer that once drew hunters to its slopes above Ketchikan. Today the Deer Mountain National Recreation Trail is the route most visitors know, climbing 2,600 feet over 2.75 miles from a trailhead inside Ketchikan through rainforest, muskeg and alpine meadow.

The main trail to the summit is well marked and takes about three hours for a round trip, with regular markers along the way to help with navigation. Weather can shift quickly, so visitors should bring proper clothing and gear to handle changing mountain conditions.
