Spice things up in Grenada, where the scent of ginger, cinnamon, and nutmeg wafts through the warm breeze. Holland America Line cruises to Saint George’s — Grenada’s quaint, red tile-roofed capital — so you can browse its aromatic market and visit a spice estate. Go tubing on the Balthazar River, gaze into the cobalt-blue Grand Etang crater lake, head to the Fort Frederick ruins for views over Saint George’s horseshoe harbor, and sip rum punch while a steel band plays on a scenic coastal cruise.
