Southern Red Sea, Sudan

For some of the most untouched scuba diving, head to the mystifying waters of the Red Sea. "The political problems all over Sudan make it difficult to get to, but also protects the diving from crowds," says Jackson. Sudan's diving requires live-aboard boats with little else to do on the boat. Spend your free time day dreaming about likely sightings of angelfish, butterfly fish, stingrays, manta rays, wrasse and other creatures flitting amongst the reefs. At 85 feet you will likely encounter Tip Reef, Silvertip, Silky and Scalloped Hammerhead sharks. Be sure to book from May to September when the weather is best.
