St. Vincent's lush 20-acre park holds a reputation as the longest standing botanical garden in the Western Hemisphere, with roots dating back to 1765. Inside, you'll encounter a broad collection of tropical flora and fauna, from flamboyant mahogany and breadfruit trees to exuberant parrots. Be sure to catch a glimpse of the garden's versatile array of natural spices—such as cinnamon and nutmeg—hanging from centuries-old tree limbs.

Recent travelers recommend visiting in the morning and tagging along on a guided tour. "You'll learn some fascinating facts about tropical plants and the grounds are much larger and more beautiful than you might expect," reports one TripAdvisor user, adding "Go early before the air heats up." You'll find the gardens just northeast of Kingstown off of Leeward Highway. The Botanic Gardens welcome visitors from 6 a.m. until 6 p.m. every day. Entrance is free; however, a guided tour costs around $5 USD, and it's considered polite to tip your guide.
