Idyllic scenery, majestic sea life, a…pirate cemetery? Surreal, serene Nosy Boraha was a once a retreat for some of history’s most notorious pirates, many of whom are buried here. The skull and crossbones-marked tombstones are among the Madagascar island’s most popular attractions. Equally attractive are the opportunities to sight amorous humpback whales, who migrate to the surrounding waters during their July to September mating season. Hiking, cycling, and reef-snorkeling round out the charming island’s appeal.
