The Riviera Maya’s rich cultural and natural heritage attracts approximately 4 million tourists a year. It is a world-class destination featuring the best of ancient and living Mayan culture. The Riviera Maya is home to both beautiful beaches and biodiversity, including the Mesoamerican Reef System, which is the largest barrier reef in the Western Hemisphere. Tourism is the key pillar of the local economy, and the phenomenal tourism growth experienced in the Riviera Maya over the past 20 years has resulted in significant impacts to its natural and cultural environment. To respond to this challenge, NGOs and the local government have actively implemented a wide range of sustainable practices in the region, including improved state-level policies and regulations for environmental protection and certification programs for hotels and tourism businesses.
