Public ferries run between Marigot Bay, St. Martin, and Blowing Point, Anguilla (tel. 264/497-6070) every 30 minutes. The trip takes 20 to 25 minutes, making day trips a snap. Usually, the first ferry leaves St. Martin at 8am and the last at 7pm; from Blowing Point, the first ferry leaves at 7:30am and the last at 6:15pm. The one-way fare is $15 ($10 children 2-18) plus a $3 departure tax. A departure tax of $20 (children $10) is charged on your return trip to St. Martin; day-trippers and visiting yachts pay a $5 departure tax. No reservations are necessary. Ferries vary in size, and none takes passenger vehicles. Tip: Keep in mind that if you have a late-arriving flight, you may quite literally miss the (ferry) boat. You can either spend the night in St. Maarten/St. Martin or arrange a charter plane connection into Anguilla.

A convenient option is to take one of the privately run charter boats and ferries that shuttle passengers between Anguilla and the airport in St. Maarten. Anguilla-based charter boats will pick you up at the Princess Juliana airport in St. Maarten and transport you and your luggage to Blowing Point or a hotel on the south side of Anguilla. These boats are more expensive than the public ferries, but let you avoid having to travel from the airport to the ferry port in Marigot by taxi (a 10- to 15-min. trip) -- a smart option for travelers with a lot of luggage or a lot of kids. Plus, the privately run boats are smaller and have fewer passengers and can even arrange full-boat charters for groups or families. Keep in mind that these boats do not run as frequently as the government-run ferry, but most do include ground transportation. Good news: In 2010, an agreement between the St. Maarten/Anguilla governments is designed to greatly facilitate the ease of private boat transfers (and passing through immigration) from the airport -- which means that ideally you will be able to get off the plane and jump on a boat straight to Anguilla in under 30 minutes.
