St. Vincent, the larger of these two islands, has a rainforest and active volcano. The beaches feature pure white sand, and they're less crowded than some of the more popular Caribbean islands. In fact, St. Vincent and the Grenadines islands are ideal for honeymooners who want privacy.
The Grenadines islands, which are populated by communities of fisherman and boat builders, are even less crowded than St. Vincent. But keep in mind that privacy and seclusion comes with a price, which is why the wealthiest of honeymooners frequent these islands.
The first "Pirates of the Caribbean" movie was filmed at St. Vincent and the Grenadines, and you can even visit some of the original set pieces, if you wish.
