The best day trip from St Martin to Anguilla begins at Blowing Point Ferry Terminal, where the crossing takes thirty minutes and the distance measures just eight nautical miles. Anguilla became a separate British Overseas Territory in 1980 after decades of political union with St Kitts, and the island's coral-limestone foundation gives its thirty-three beaches the pale sand and turquoise clarity that define the Caribbean postcard. The ferry service operates seven days a week from 07:00 to 19:00, connecting Marigot on the French side of St Martin to Blowing Point on Anguilla's western shore. The island spans sixteen miles east to west and three miles at its widest point, making it possible to traverse the entire landmass in an afternoon. Shoal Bay East anchors the northern coast with two miles of uninterrupted sand and a fringing reef that holds sea turtles, parrotfish, and southern stingrays in water shallow enough to stand. Meads Bay on the western shore runs calmer, its crescent protected by headlands and dotted with beach bars that serve grilled mahi-mahi and rum punch under thatch roofs. Rendezvous Bay stretches three miles along the southern coast, facing St Martin across the channel, its sand so fine it compresses underfoot like talcum. Anguilla's population of sixteen thousand lives mostly in The Valley, the capital village set inland from Crocus Bay, and the island's economy pivots on tourism and offshore finance rather than agriculture or manufacturing. The south coast catamaran cruise from St Martin includes snorkeling stops at Sandy Island, a one-acre sandbar ringed by elkhorn coral, and Little Bay, accessible only by boat and sheltered by limestone cliffs that rise sixty feet. Private boat charters allow custom itineraries, visiting multiple coves in a single afternoon, while guided island tours cover the East End villages, the Wallblake House plantation ruins from 1787, and the Heritage Collection Museum, which holds Arawak artifacts dating to 1300 CE. The departure tax at Blowing Point costs five US dollars for day trippers, paid in cash upon arrival, and the terminal operates without advance reservations for walk-on passengers. The best arrival window falls between 08:30 and 10:30, maximizing daylight hours for beach exploration before the final ferry departs at 19:00. Passport requirements follow British Overseas Territory protocol, meaning US and Canadian citizens need only proof of citizenship, while EU nationals require a valid passport.
