For the adventurer looking for the unknown and the untouched, we’ve compiled a list of where—and when—to get your fix.
Cenderawasih Bay, Indonesia
Cenderawasih Bay is located in northern Provence of Papua, just above Australia. Its major draw is the spectacular whale shark encounters, where divers mingle with the docile creatures as they swim, mouths agape feeding on plankton. Dive Damai—a full-service live-aboard dive excursion for up to 12 guests—is a traditional Indonesian wooden phinisi with a four-to-one guide-to-guest ratio. After a day’s dive, 18 local crew and two western cruise managers pamper their passengers with palm oil-free products, massage treatments, and meals made up of local seafood. Best time to go: July through September; from $560 per person per night; 62-361/284-359; dive-damai.com.
