This park's name comes from a Papiamento phrase that translates as "seven mouths"—a reference to its seven natural inlets. The park showcases a spectacular cavern, Boka Tabla, carved into limestone cliffs on the north coast by millions of years of pounding surf. Steps lead down into the cavern, and a path on the bluff above takes you to the edge where you can watch the crashing waves. For hikers, there are trails along the bluffs. To ensure security, the park service now asks for a US$1.50 fee to patrol the parking area, but it's always wise to lock your car, and don't leave anything valuable inside.
