You dont "wheel" on the OBX but you can drive on the beacj in designated areas. Stay the fawk off the dunes as access is threatened right now by the NPS and green groups.
If you wheel on the dunes I hope you roll and the seagulls peck your eyes out.
Yep - no driving on the dunes. The only place I know of where you are allowed to drive behind the dunes is up north of Carolla in the unpaved area. There are legitamate cut-throughs to get from the beach to behind the dunes, where there are sand roads all behind the dunes - that's how people get to their houses. Look Carova up online if you are interested - if you can find a map of the roads up there, it looks like a giant neighborhood, but it is all sand roads and some of it goes through "maritime forest".
The roughest part of the beach is as far north as you can go. There is a fence at the Virginia line that keeps you from driving into Virginia. Since that's the end of the road, few people go up that far, so the sand is the deepest up there, if that's what you are looking for.
To give you an idea of the terrain, I drove my 1990 Burb with rear locker and 33x12.50 MTs aired down to 20 psi. Used low range (so not to overheat the auto trans), and had no problem. Friend had a 1987 Burb out there with no rear locker and 265/75/16 tires (smaller than mine), but aired-down he also had no prob. Other friend had stock Grand Cherokee on stock small street tires aired down, and he got though everything to the house we stayed at, but I'm sure he could have gotten stuck in some of the bad places if not careful.
There was some interesting stuff north of Corolla in February since no one else was out there (HEAVILY rutted and soft beach, and no one had driven on the roads behind the dunes). But now during the summer the beach gets so packed that you probably don't have to use 4WD unless you go behind the dunes. Watch it when you leave Hwy 12 and first get on the beach - there are stumps all over the beach. We asked the fire/rescue folks if anyone ever hit the stumps, and they said that people who hit those stumps usually die - they are going 35 mph and hit a solid stump at axle level and flip over onto their roof!
