The island's lush geography lends itself to eco-tourism, starting with the dense tropical rainforests that surround dormant volcano Mount Liamuiga. Colorful birds and butterflies, as well as the green vervet monkey, reside here. Sugar cane, the staple of the economy since the 17th century, was St. Kitts' main export until production stopped just a few years ago. However, wild sugar cane fields remain, particularly in the west, and offer a scenic ambience that is more reminiscent of Hawaii than the Caribbean these days. While tourists have discovered St. Kitts (evidenced by the row of lively beach bars on South Frigate Bay, known as "The Strip"), the island is still relatively unspoiled and crowd-free, with a relaxed, authentic atmosphere.
