4x4, hike, 4x4
Gemini Bridges is a 4wd road that connects Highway 191 and Highway 313 just north of Moab. Near the middle of the route is 2 natural bridges right next to each other known as The Gemini Bridges. A short hike is required to see the bridges.
This route can be driven in either direction. The popular way is to stat on the Moab side (191) and end on 313. This could be used as a very scenic way to enter Canyonlands National Park (Island in the Sky) or Dead horse point State Park. Alternatively it could be ran the other direction as an alternative way back into town.
Starting from 191 the trail quickly climbs up a narrow shelf road. the views up here are spectacular and you can tell just how high up you really are based on how small the cars look below on the highway. Once you climb back down you will be on a sandy route that crosses in front of Gooney Bird Rock. There is also a BLM camping area in this vicinity. You'll start a short rocky climb soon, the rocks aren't that big, but a high clearance vehicle will be required. 4wd would be helpful. The rocky section has been ground down, I'm sure back in the day it was much more challenging. Soon after you will reach the Gemini Bridges trail head. Its a short hike, less than a mile, down to the bridges. The bridges are cool to check out, you can even walk on them, just don't try to jump the gap. The gap is 6-10 feet wide in some areas and there is a history of people not making it a across, check google if interested. After Hiking back and getting in your vehicle the trail to Highway 313 is pretty easy going, a mostly graded dirt road. The BLM has done a good job marking the trail.
It should be noted there are several other 4x4 trails that branch off of Gemini Bridges and most are of a more difficult level. There are also several single track mountain bike trails in the area that cross over this route, keep your eyes out for mountain bikers.
