Every boater remembers the first time they spotted a lighthouse on the horizon.
Long before electronic navigation transformed life on the water, these towers served as guardians of the coast, warning mariners of rocky shorelines, hidden shoals, and dangerous passages. For generations, they guided vessels safely into harbor and became symbols of the communities they protected.
Today, many of Narragansett Bay's most historic lighthouses remain active. While their role has evolved, they continue to define the Rhode Island coastline and offer some of the most rewarding destinations for boaters exploring New England waters.
Beavertail Lighthouse
Standing at the southern tip of Jamestown, Beavertail Lighthouse is one of Rhode Island's most recognizable landmarks and one of the oldest lighthouse sites in North America.
The current tower dates to 1856, but navigational aids have existed on this point since the eighteenth century. For boaters approaching Narragansett Bay from the Atlantic, Beavertail remains one of the first landmarks to come into view.
The rocky shoreline surrounding the lighthouse offers dramatic views of the ocean and serves as a reminder of why navigation was once so critical along this stretch of coast.
Castle Hill Lighthouse
Few lighthouses are more closely associated with Newport than Castle Hill.
Located at the entrance to Newport Harbor, the lighthouse has welcomed vessels arriving from Narragansett Bay since 1890. The compact granite structure sits atop a rocky point and remains one of the most photographed locations in Rhode Island.
For boaters, passing Castle Hill often marks the beginning of a Newport adventure.
Rose Island Lighthouse
Situated on a small island between Newport and Jamestown, Rose Island Lighthouse occupies one of the most strategic locations in Narragansett Bay.
Built in 1870, the lighthouse once guided vessels entering Newport Harbor and served as an important navigational aid for commercial and military traffic.
Today, it stands as a beautifully restored reminder of Rhode Island's maritime history.
Dutch Island Light
Located in the West Passage, Dutch Island Light has watched over Narragansett Bay since the nineteenth century.
The lighthouse occupies a quieter corner of the bay than some of its more famous counterparts, making it a favorite among local boaters looking to explore beyond the busiest routes.
The surrounding waters offer a glimpse into a different side of Narragansett Bay, one defined by open space, scenic shorelines, and a slower pace of life.
Point Judith Lighthouse
Standing guard at the entrance to Point Judith Harbor, this lighthouse has guided mariners along Rhode Island's southern coastline for more than two centuries.
The current granite tower dates to 1816 and remains one of the most important navigational landmarks in the region. Positioned near one of New England's busiest fishing ports, Point Judith Light has long served as a waypoint for commercial vessels, recreational boaters, and mariners traveling between Narragansett Bay and destinations farther east.
For many cruisers, spotting Point Judith marks the beginning of a voyage toward Block Island or the return home after a weekend spent exploring Rhode Island waters.
Why Jamestown Is the Perfect Starting Point
One of the advantages of keeping your boat in Jamestown is that many of Narragansett Bay's most iconic landmarks are within easy cruising distance.
From Beavertail and Rose Island to Castle Hill and Dutch Island, boaters can spend an entire day exploring centuries of maritime history without venturing far from their home port.
Located in the heart of Narragansett Bay, Conanicut Marina provides convenient access to some of the region's most scenic cruising routes, making it an ideal launching point for discovering Rhode Island's legendary coastline.
