North America East Coast Cruise

New York City to Cape Cod: Whales, Great White Sharks & Seafaring History

Embark the 62-guest Nat Geo Sea Lion to explore New York City, Long Island Sound, Cape Cod and beyond on this 8-day cruise. Near large East Coast population centers are magical natural worlds where undeveloped, under-the-radar islands serve as critical resting, nesting, and feeding grounds for migratory birds and mammals. Explore remote archipelagos in three states that are refuges for thousands of common and roseate terns and tens of thousands of gray seals. The marine ecosystems are equally fascinating with eelgrass meadows, corals, sponges, and an underwater plateau that draws 17 species of whales, creating New England’s only national marine sanctuary. Cruise from New York to Boston, or reverse, and explore picturesque seaside towns, lighthouses and historic forts, plus get an insider’s look at leading scientific research stations and important conservation efforts.

These Long Island Sound cruises offer a plethora of high points. Hike, kayak, and Zodiac-cruise little known archipelagos along the north shore of Long Island Sound. See historic whalers, schooners and well smacks at Mystic Seaport, the largest maritime museum in the world. Visit Plum Island, a haven for wildlife and bird species, and learn from a Nature Conservancy conservation specialist about efforts to save the island from development. Explore and learn fascinating histories of islands like Penikese Island—a former leper colony. And learn about the diverse ecosystems of the area by speaking with researchers doing important conservation work. Watch for whales in some of the richest marine waters in North America. Search the Atlantic for great white sharks along the outer shores of Cape Cod.

Board the small and agile 62-guest National Geographic Sea Lion to cruise from New York to Boston (or reverse). Explore under the sure guidance of an expedition leader and five veteran naturalists, including a National Geographic certified photo instructor, plus a wellness specialist. The expedition staff’s insights into the region make these Long Island Sound cruises an unforgettable experience.

Plum Island

Today the ship will pick up a local conservation specialist from The Nature Conservancy who will join for the cruise around Plum Island. They’ll speak about their ongoing efforts to save this 840-acre island from going on the auction block and being developed. The island is a haven for wildlife: it’s the location of the largest seal haul-out in New York, hosts over 220 species of birds and is rich in ecological diversity. It was also home to Fort Terry from the Spanish American War until World War II and is currently the home of the world-renowned Plum Island Animal Disease Center.

Penikese Island & Woods Hole, Massachusetts

Today, make the first of several stops in Massachusetts waters. The fascinating tales of little-known Penikese Island, part of the Elizabeth Island archipelago, come alive. Human use of the island has gone through many different permutations including serving as a leper colony. While walking along the trails, hear stories of the island, now allowed to return to its natural state. While dining on lunch on board, sail towards Woods Hole, the quiet, Cape Cod town that is home to one of the leading marine laboratories in the world–Woods Hole Oceanographic Institute. Here enjoy a behind-the-scenes tour of this top facility, learning about the many projects worldwide in which the institute is involved.

Monomoy Island National Wildlife Refuge & Chatham

Arriving at the elbow of Cape Cod today, take the Zodiacs to the quiet shores of Monomoy National Wildlife Refuge. An extremely important stop for migratory shorebirds, Monomoy will be a hotbed of activity this time of year with numerous species including Hudsonian godwits, red knots and black-bellied plovers in their stunning spring finery, refueling before setting north again to breeding territories on the Arctic tundra. Over lunch, sail past Monomoy, out of Nantucket Sound and into the Atlantic. Off Chatham, be joined by Atlantic White Shark Conservancy staff to learn about the apex predator’s return to Cape Cod waters and to watch for great whites that frequent the area from June to October.

Day 7
Provincetown & Stellwagen Bank Natl. Marine Sanctuary

Overnight, the ship has navigated along the outer side of the peninsula arriving to the tip of Cape Cod: Provincetown. Choose to tour the many galleries in town, with its thriving community of artists. Or opt to explore the Cape Cod National Seashore farther south. At the Wellfleet and Eastham communities and touring the Three Sisters Lighthouses and the beautifully restored Atwood-Higgins house, learn about the history of the Cape. Construction was completed in 1730, making it likely the oldest house on the Cape. George Higgins donated the house and the many out-buildings on the property to the National Park Service in 1961. And of course as the ship continues this tour of the National Seashore, be always on the lookout for wildlife. The Cape is home to 450 species of amphibians, reptiles, fish, birds and mammals. Back on board, enjoy lunch as the ship departs into the whale-rich waters north of the Cape and on to Stellwagen Bank, always on the lookout for the cetaceans of the Atlantic, which may include humpback, finback whales and, with a great deal of luck, the highly endangered northern right whale. As the sun sets, turn towards Boston Harbor.
