Luna Lake is a natural body of water that covers approximately 75 acres (0.30 km) of land. It is located about three miles (5 km) southeast of Alpine, Arizona, at the elevation of 7,890 ft (2,400 m), and is the centerpiece of the Luna Lake Wildlife Area.

Luna Lake has the distinction of being part of the San Francisco River, flowing easterly into New Mexico, then south, and west into the Gila River (in Arizona). The headwaters are north of the other main mountain tributary to the Gila, the Blue River of Arizona.

Luna Lake lies at 7,890 feet (2,400 m) on the Apache-Sitgreaves National Forests, as such the facilities located here are managed by that authority. It is located about 3 miles (4.8 km) east of Alpine. It’s accessible year-round, but ices over in winter months.

Luna Lake is a 75-acre (300,000 m) impoundment of the upper San Francisco River. It has a maximum depth of 21 feet (6.4 m) and an average depth of 8 feet (2.4 m). It is stocked annually with fingerling and subcatchable rainbow and cutthroat trout. Because it is a shallow, nutrient-rich lake, it is subject to water quality problems and excessive weed growth. The Arizona Game and Fish Department annually harvests weeds to help alleviate some of the water quality problems.
