Lush and luxuriant, the exotic tropical island nation of St. Kitts and Nevis is a romantic paradise. St. Kitts' wonderful beaches remain relatively crowd-free, and nature lovers delight in seeing lava formations, tropical forest and lagoons and underwater marvels while snorkeling or diving. Among more than 200 historical sites, former plantation homes now offer elegant accommodation. Eco-rambles, bio-tours and climbing are Nevis attractions. Rent cars or mopeds on-island and catch ferries between the two.
