Both St. Kitts and Nevis are steeped in history; Brimstone Hill Fortress is a man-made UNESCO World Heritage site.
Luxurious, restored plantation inns can be found on both islands.
Both islands have extinct volcanoes and luxuriant rain forests ideal for hikes, as well as fine diving and snorkeling sites.
You'll find less development—particularly on Nevis—and more cordial and courteous islanders than on more touristy islands.
