Tulum is a town on the Caribbean coastline of Mexico’s Yucatán Peninsula. It’s known for its beaches and well-preserved ruins of an ancient Mayan port city. The main building is a large stone structure called El Castillo (castle), perched on a rocky cliff above the white sand beach and turquoise sea. Near the ruins is the Parque Nacional Tulum, a coastal area with mangroves and cenotes (natural limestone sinkholes).
Montego Bay, the capital of Saint James Parish on Jamaica’s north coast, is a major cruise ship port with numerous beach resorts and golf courses outside its commercial core. Popular beaches include Doctor’s Cave Beach and Walter Fletcher Beach, home to an amusement park. There’s also snorkelling and diving at coral reefs in the protected waters of Montego Bay Marine Park.
