And they have intersections without signs or lights...they have "round-a-bouts", which means you need to be assertive and just hold your breath. Don't hesitate or you will get run down. I want to re-iterate... The West end is just a shadow of its' former self from 25-30 years ago. Cruise ships, sewage, boat traffic, litter, and reckless people tearing up the reef. The shipwreck might be the only reason to go North-West. The east side is healthy and there are more sites and dives than you can possibly do in 2 weeks, much less 3 days. If you want shipwrecks go to Grenada or the Florida Keys, but you won't find East end reef except for Brac.
