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 snorkelling or diving. Among more than 200 historical sites, former plantation homes now offer elegant accommodation. Eco-rambles, bio-tours and climbing are Nevis attractions. Hire cars or mopeds on-island and catch ferries between the two.
