Jacob Lake is a small unincorporated community on the Kaibab Plateau in Coconino County, Arizona, United States, at the junction of U.S. Route 89A and State Route 67. Named after the Mormon explorer Jacob Hamblin, the town is known as the "Gateway to the Grand Canyon" because it is the starting point of Route 67, the only paved road leading to the North Rim of the Grand Canyon some 44 miles to the south. The town itself consists of the Jacob Lake Inn which maintains motel rooms and cabins, a restaurant, lunch counter, gift shop, bakery, and general store; a gas station/garage; campground; and a visitors center run by the U.S. Forest Service. In the summer months, there is also a nearby center for horse rides.
Jacob Lake is situated at roughly 8000 feet in a large ponderosa Pine forest which is part of the Kaibab National Forest. In its lower elevations, the Kaibab Plateau consists of pinon-juniper forests, and the ponderosas give way to aspen, spruce, and fir higher up. However, the ponderosa biosphere is home to the endangered Kaibab Squirrel. Jacob Lake is also home to mule deer, coyotes, porcupines, bobcats, numerous bird species, horned lizards, and mountain lions.
