Home to nearly 500 miles of idyllic Caribbean beaches and crystal-clear turquoise waters, Honduras offers some of the world's finest sand and sea. Underwater discoveries abound for snorkeling and diving enthusiasts in the Bay Islands of Roatan, Utila and Guanaja. A tropical paradise of swaying palms and white sand, these secluded islands are surrounded by the spectacular Mesoamerican Barrier Reef. Adventure-seekers can swim with dolphins and whale sharks here year-round, or learn to windsurf in the destination's tranquil coves. For a more laid-back approach, visitors can enjoy activities like kayaking, glass bottom boat rides, sailing or simply lounge on the pristine shoreline.
