Travelers come to this small island north of mainland Cuba to bask in the sun, swim in sparkling blue water, and be pampered at an all-inclusive resort. To explore Cuban culture, you’ll need to go farther afield (this is a planned resort development; employees are bused in), but if you’re simply looking for a stress-free tropical break, Cayo Santa Maria might be perfect for you.

Sleepy and secluded Friday Harbor is a tiny town with big personality and rich history.

Stroll through the Historic District, visit informative museums, explore the Port of Friday Harbor waterfront park and see the local populations of orcas and whales from the shore.
