Fort Bliss, one of the largest military complexes of the United States Army, lies to the east and northeast of the city, with training areas extending north into New Mexico, up to the White Sands Missile Range and neighboring Holloman Air Force Base in Alamogordo. The Franklin Mountains extend into El Paso from the north and nearly divide the city into two sections, the western half forming the beginnings of the Mesilla Valley and with the eastern slopes connecting in the central business district at the south end of the mountain range.El Paso is located at 31°47'25?N 106°25'24?W (31.790208, -106.423242).

The Rio Grande Rift, which passes around the southern end of the Franklin Mountains, is where the Rio Grande flows. The river defines the border between El Paso from Ciudad Juárez to the south and west until the river turns north of the border with Mexico, separating El Paso from Doña Ana County, New Mexico. Mt. Cristo Rey, a volcanic peak (an example of a pluton) rises within the Rio Grande Rift just to the west of El Paso on the New Mexico side of the Rio Grande. Other volcanic features include Kilbourne Hole and Hunt's Hole, which are Maar volcanic craters 30 miles (50 km) west of the Franklin Mountains.
El Paso is surrounded by the Chihuahuan Desert, the easternmost section of the Basin and Range Region.
Being in the westernmost tip of Texas, and due to the huge size of the state, El Paso is closer to four other state capitals (US and Mexican) than it is to its own capital of Austin, Texas.
