In the last Frommer's cruise newsletter we presented a list of the top active adventure excursions in Alaska, according to our poll of the expert shore-excursion staff at the cruise lines -- the people who find, test out, contract, and then manage all the shore excursion the lines offer. This week we turn to the Caribbean, still the #1 cruise destination and home to more than 600 excursions, from ho-hum bus tours to daylong hikes up the side of a volcano.

Excursions listed are those revealed by a poll of shore-excursion managers at the Big Four cruise lines -- Carnival, Royal Caribbean, Princess, and NCL, concentrating on both active adventures (hiking, kayaking, mountain biking, etc.) and "experiential" adventures (ATV and jeep tours, volcano tours, and so on). Since cruise lines contract with landside tour operators to manage their excursions, most offer a similar list of excursions. Still, the cruise lines' answers didn't always match. Different takes on what "adventure" means? Maybe, but that just gives you more meat to chew on.

Note: All prices are averages. Actual prices may vary by a few dollars.
