"Yah-ta-hey" or "Yá-át-ééh",
I-8 to Casa Grande area & I-10....nothing much in the way hills. I-10 to El Paso, not much at all, unless you take Trans Mountain Rd. (Closer to get on the hwy. to Carlsbad Caverns). Crest is 5280' at Smuggler's Pass.
Tucson/Arizona, New Mexico & Texas ---- Guadalupe Pass - Elevation: 5,424'
Near Carlsbad Area TX/New MexicoOne can use the War Road Route to bypass the Trans Mountain pass: Use Exit 162 in New Mexico (just short of the NM/TX state line) NM-404/Ohara Rd East, turn right on NM 213 S (War Road), this turns into Martin Luther Kings Jr. Blvd (FM 3255) once entering TX. Take the ramp onto Gateway S Blvd/Patriot Fwy (US 54 S) to TX 376 Turn left onto Woodrow Bean Trans Mountain Rd (Texas Loop 375). Follow Loop 375 to the US-62/US-180/Montana Ave exit (about 12 miles). The US-62/US-180 takes you to Carlsbad Caverns. Not mountains to cross on this bypass. If you take a right on 376, then it'll take you up & over the pass.
If you want to take the Pass, just stay on I-10 on into TX. Take the exit toward Texas Loop 375/Trans Mountain Rd (about 5 or 6 miles from state line)....Turn left onto TX-375 Loop W/Woodrow Bean Trans Mountain Rd it will take you up & over (great vistas up at the top, at a rest/viewing area).
Video Drive Trans MountainYou really do not want to drive into El Paso & do a few city streets to get to & onto very busy Montana Ave (US-180 E/US-62 E). Much worse than a mountain pass.
Post Edit: Between Benson & Wilcox, a mild pass with a rest area in Texas Canyon, neat rock formations - elevation 4500'.
Also In the area: The Amerind Foundation
:C Clicky :C ( Amerind Art Gallery is Neat ) a ethnological, anthropological, archaeological museum and art gallery with paintings by 20th century Anglo and Native American artists. We enjoyed the art gallery and the museum. A neat out of the way, hidden site in the boulders of Texas Canyon. The Amerind is located in Cochise County, one mile south of Interstate 10, only about an hour east of Tucson, between Benson and Willcox. It is easy to find - just look for Dragoon Road exit, #318, and head south until you see mile marker 1 on one side of the road and the Amerind entrance on the other.
Cochise Strong Hold is in the same area, drove to it but did not camp, a nice setting.
Cochise StrongholdEastbound I-10 into Benson, will descent into the San Pedro River valley, then a climb out of the valley & somewhat a gradual climb to the pass at Texas Canyon. A little descent from Texas Canyon on the way to Wilcox. Some 18 wheeler get slow on the ascent. Not too bad.
