Geography

Diamond Ridge is located at 59°39′55″N 151°34′15″W (59.665391, -151.570826) and is bordered to the south by the city of Homer and to the southeast by the city of Kachemak. To the east is the Fritz Creek CDP, while to the north and west is the Anchor Point CDP. The farthest west part of the Diamond Ridge CDP borders Cook Inlet at the mouth of Kachemak Bay.

The area is named for the high ground, Diamond Ridge, on which it sits. The ridge reaches an elevation of 1,202 feet (366 m) above sea level and is in the southern part of the CDP. Parallel landforms to the north are Crossman Ridge in the center of the CDP and a ridge connecting 1,513-foot (461 m) Ohlson Mountain and 1,622-foot (494 m) Lookout Mountain in the north. The terrain slopes north from the ridges to the Anchor River, which forms the northern boundary of the CDP.

According to the United States Census Bureau, the Diamond Ridge CDP has a total area of 42.4 square miles (109.8 km²), of which 0.004 square miles (0.01 km²), or 0.01%, are water. The main access is via Diamond Ridge Road, which runs across the top of the 5-mile-long (8.0 km) ridge and connects to feeder roads on either side.

Parks and trails

The Homer Demonstration Forest

Diamond Ridge is home to two park areas with trail systems. One is the Homer Demonstration Forest, a preserve on the slopes just below the actual ridge itself. It contains an arboretum, self-guided nature trails, and is one end of the Homestead Trail which crosses the demonstration forest, climbs up Diamond Ridge and across a deep valley to Crossman Ridge, eventually ending at the Homer Reservoir. In winter months there are extensive groomed trails for cross-country skiing, as well as a snowshoe trail.

The Diamond Creek Trail follows a deep ravine to the beach near where Kachemak Bay meets Cook Inlet.

The other park in the area is the Diamond Creek State Recreation Area. This is a newer unit of Alaska State Parks and has little development. It is day-use only, camping is not permitted, and the access road is steep and extremely rough in places; vehicles over 25 feet (7.6 m) are not permitted on the lower part of the road. The road leads to several parking areas for access to hiking and biking trails. The bike trails are constructed and maintained by a local cycling club.
