Things to Do in Stone Harbor
Stone Harbor sits on Seven Mile Island in Cape May County, New Jersey, sharing that island with Avalon to the north -- a borough Wikipedia's own 2020 census figures put at just 796 year-round residents, even as its summer population swells past 20,000. One real, well-documented attraction anchors a day of sightseeing here, and it is not invented: the Stone Harbor Bird Sanctuary, a 21.5-acre protected area established by local ordinance in 1947 and designated New Jersey's first National Natural Landmark in October 1965. Stone Harbor also carries a genuinely, independently confirmed identity as one of the most upscale towns this site has covered on the Jersey Shore -- The New York Times has described it as a place of "gleaming McMansions and elegant shops." This page sticks to what our research confirmed -- it does not invent current sanctuary hours, admission costs, current nesting-population counts, or the names of specific present-day shops or restaurants.
The Stone Harbor Bird Sanctuary: New Jersey's First National Natural Landmark
Herons naturally began nesting on this stretch of Seven Mile Island around 1938, and the borough formalized protection for the site by local ordinance in 1947, setting aside 21.5 acres as the Stone Harbor Bird Sanctuary. The town fenced the property in 1961, and in October 1965 the sanctuary was designated New Jersey's first National Natural Landmark -- a real, documented federal recognition that predates almost everything else built on this stretch of the Jersey Shore.
By 1964, more than 5,000 birds were arriving here annually for nesting season, which historically ran from March through July, with birds staying on site until December. Historic species recorded at the sanctuary have included snowy egrets, glossy ibis, black-crowned and yellow-crowned night herons, little blue herons, green herons, and tri-colored herons -- a documented list, not a marketing description, of what once nested in this small patch of protected habitat.
A Real Conservation Mystery: The 1995-2000 Disappearance
The sanctuary's history includes a genuinely dramatic, unresolved chapter. Beginning around 1995, nesting shorebirds "mysteriously disappeared" from the site, and the colony had nearly vanished by 2000. Our research this pass did not confirm a specific cause -- predation, pollution, disease, or otherwise -- so this page does not speculate on why it happened. It is presented here as a real, documented event with an undetermined cause, not as a solved case.
In response, a 2005 rejuvenation project began working to restore the habitat: increasing tidal water flow through the site, removing invasive vegetation, and removing feral cats. Later surveys have documented warblers, woodpeckers, and hawks using the site, though our research did not confirm current, post-2005 nesting-population counts, so this page does not invent a specific figure for how the colony stands today.
What Makes Up the Sanctuary Today
The sanctuary itself is a mix of habitat types within its 21.5 acres: dense vegetation, a freshwater pond and meadow, and maritime forest. It sits close to Nummy Island's salt marsh, which historically has served as a feeding ground for the birds nesting at the sanctuary -- meaning a visit to Stone Harbor's own protected acreage connects directly to a wider, real wetland system rather than standing alone.
Our research did not confirm current visitor hours, any admission fee, current trail conditions, or current guided-tour offerings at the sanctuary. Confirm current access details directly with the Borough of Stone Harbor before planning a visit around it.
"Gleaming McMansions and Elegant Shops": A Real, Confirmed Identity
Beyond the sanctuary, Stone Harbor carries a genuinely distinct character among the New Jersey shore towns this site has covered so far. The New York Times has described the borough as a place of "gleaming McMansions and elegant shops," and in 2017 it ranked as the third-most-expensive ZIP code in New Jersey by median home sale price; in 2014, Forbes ranked it 191st among America's most expensive ZIP codes nationally. Those are dated figures, cited here as historical data points rather than a claim about today's market.
That upscale identity shows up in the borough's own population swing: a year-round population of just 796 as of the 2020 census gives way to a summer population exceeding 20,000, a seasonal group Wikipedia describes as typically wealthier than the town's own year-round residents. Our research did not confirm the current names of specific shops, restaurants, or boutiques behind the "elegant shops" description, so this page does not invent any -- browse Stone Harbor's own commercial district in person or confirm current business listings directly with the borough or individual merchants.
A Founding Shared With Avalon
Stone Harbor's own history is tied to its island neighbor. The Seven Mile Beach Company purchased all of Seven Mile Island in 1887 and founded both towns from that single corporate entity -- Avalon on the island's northern half, Stone Harbor on its southern half. Stone Harbor's own development began in 1891 with an inn and seven cottages near 80th Street, and the borough was formally incorporated in 1914 following an act of the New Jersey Legislature.
The town's own name carries a real, documented legend: it is credited to an English sea captain named Stone, who is said to have taken refuge behind Seven Mile Island during a severe storm. It is a small piece of local history that predates the bird sanctuary by decades and gives the town its own identity apart from Avalon's, even though both share the same island and the same 1887 founding company.
What This Page Does Not Invent
This page is built around what our research confirmed: the Stone Harbor Bird Sanctuary's 1947 establishment as a 21.5-acre protected area, its October 1965 designation as New Jersey's first National Natural Landmark, the more-than-5,000 birds recorded nesting annually by 1964, the historic species list, the 1995-2000 disappearance of nesting shorebirds and the 2005 rejuvenation project that followed, the sanctuary's mix of dense vegetation, freshwater pond and meadow, and maritime forest near Nummy Island's salt marsh, The New York Times's "gleaming McMansions and elegant shops" description, the 2017 and 2014 expensive-ZIP-code rankings, the borough's 796-resident 2020 census population against a summer population exceeding 20,000, and the shared 1887 Seven Mile Beach Company founding of Stone Harbor and Avalon.
It does not state current bird-sanctuary hours, admission costs, current nesting-population counts, the specific cause of the 1995-2000 disappearance, current median home prices, or the names of specific present-day shops or restaurants, because none of those details were confirmed during our research pass. Confirm current sanctuary access, current business listings, and current market data directly with the Borough of Stone Harbor before planning a visit around them.
