Hmmm, did it about 5 years ago in new diesel Jeep cherokee with standard tyres. After that experience, unless they have fixed the tracks in the middle of the island wouldn't consider taking my Tig there.
As the others said, very soft sand, deep ruts, not good for the Tig at all without some serious mods and better tyres. We had the Jeep bogged a few times.
