On the Waterfront Some 200 years ago, the writer Henry Nelson Coleridge called Grenada a “poet’s Arcadia.” And for decades to come, the tiny Caribbean island, with its powerful waterfalls that flow into the sea and fragrant nutmeg trees, remained an insiders’ secret. The opening of the Bali-inspired Laluna Resort (cottages from $730) and the more recent Mount Cinnamon Beach Resort (doubles from $500), on a white-sand beach, heralded a new level of sophistication. But Grenada’s authenticity and natural appeal remain. One-sixth of the land is protected wilderness, including Grand Étang, a crater lake set atop an extinct volcano. Farmers still sell fresh fruit and spices at the market, and in the French-colonial capital, St. George’s, the winding roads are lined with boutiques like Tikal, which carries local crafts. On Friday nights, listen to steel drums at the fish fry that takes over the small village of Gouyave. End your day at the beachside Aquarium (dinner for two $60), for West Indian barbecue served beneath the stars.
