Caribbean Nature Park of the Year: The Tobago Main Ridge Forest Reserve Set on nearly 10,000 acres in the northeast of Tobago, this isn’t just one of the natural wonders of the Caribbean; it’s the oldest protected rainforest in the western hemisphere. That means it’s a living example of the power of conservation and one whose continued stewardship sends a daily message to the rest of the region. It’s also one of the most remarkable places to visit in the region, a haven of biodiversity and a portal into the natural splendor of this gem of the Southern Caribbean.
