Big Lake is a high mountain peak at an elevation of 2.870m (9,415ft) above the sea level, located in Apache County, in the U.S. state of Arizona. It's one of the highest mountain roads of Arizona.
The road to the summit, located within the Apache-Sitgreaves National Forests, is gravel and rocky. It’s called Forest Road 24B. Avoid driving in this area if unpaved mountain roads aren't your strong point. 4x4 required. Stay away if you're scared of heights. Expect a trail pretty steep. At the summit it was a fire lookout tower built in 1933. Remodeled in 1967, the tower is 30 ft. tall and has a 12 ft. square observation area. For your safety, be sure to check the weather forecast before you begin your trip. If there is a thunderstorm in the area, please do not visit a lookout. The trail is open from April through November, depending on snowpack.
