Looking for something unusual to do this summer? How about exploring the remains of the Titanic from an Mir submersible vehicle at 12,500 feet below sea level? Fifteen-day excursions will begin July 12, July 27 and August 6 and will include lectures and a ceremony to mark the 100th anniversary of the Titanic’s sinking. The per-person cost ($66,257 for submarine divers, $12,498 for non-submarine divers) also covers pre- and post-expedition tours in Halifax, Nova Scotia, and St. John’s, Newfoundland. For more information, contact Kensington Tours at (888) 903-2001.

Want to explore the Titanic without getting wet? Visit the renovated Harlan and Wolf Shipyards, a $100 million state-of-the-art attraction on the site in Belfast, Northern Ireland, where the “unsinkable” vessel was built and launched. Multimedia exhibits focus on the Titanic’s construction and sinking and a live video link lets you view the wreck on the ocean floor. Additional reasons to visit Northern Ireland include the Giant’s Causeway, a World Heritage Site; the charming Antrim Coast; historic castles and castle hotels; first-rate golf courses; and, of course, plenty of Guinness.
