More ways to explore the area's outdoor wonders
Early light on the Indian Ocean turns the water a hard, brilliant blue; a motorboat hums away from the coral-fringed shore and the day snaps into motion. Travelers find themselves cutting across open water toward Mnemba Atoll where dolphins often ride the bow wave and coral gardens wait beneath crystalline surface. Later the route swings toward mangrove-shaded boardwalks and the fossilized limestone of Prison Island, each stop delivering a different rhythm and color to the day.
