I’m not sure exactly how Rainbow Beach got its name, though I wouldn’t be surprised if it actually had a lot to do with rain. The island’s most popular beach bar, especially on Sundays, is centrally located on St. Croix’s West Coast, some of the island’s tallest peaks and dense rainforest just a few miles behind it. Prevailing weather patterns, particularly during the summer months, make brief afternoon showers a fairly regular occurrence here. That doesn’t stop the party, though. Live bands play on and everyone keeps dancing. When you’re already wet from the sea and feeling the vibes, a little rain doesn’t hurt one bit.
