I used to drive on the beach at Birdlings, Bailies and Amberly with no problems. 4X4 bighorn with 31×10.5 tires and ltd slip diffs front and back. Pays to carry a compressor so you can pump your tires back up if you have to let a bit of air out to get some xtra grip. I always carried a shovel and a set of super grippers just in case. Avoid wheel spin and you shouldnt need to worrie about the shovel.
