Your cruise ship will berth at the 1,526 foot Frederiksted Pier. Most disembarking passengers scurry off to join an excursion, hire a taxi or find a guide to start exploring the island. But not so fast! This pier is a mecca for underwater aficionados. Snorkeling is ideal here. You will see seahorses, batfish and frogfish swimming among the coral at 25 to 50 feet. You might also spot moray eels and octopus. If you prefer scuba diving, then discover several ship wrecks embedded in a colorful reef a short distance away. Or take the plunge off the pier! The water is fine with an average temperature of 80°F.
