South Brother Island is a tiny, uninhabited island in the East River off the Bronx, New York, known for its raw natural solitude, layered history, and remarkable urban wildlife habitat.
South Brother Island is a small, uninhabited island of roughly three acres sitting in the Hell Gate section of the East River, administratively part of the Bronx. Its neighbor, North Brother Island, lies just half a kilometer to the north and shares a similarly layered and largely forgotten history within New York City's geography.
The island was once owned by baseball legend Babe Ruth, who used it briefly as a private retreat in the early twentieth century. Before that, it changed hands several times without ever developing the kind of institutional presence that defined North Brother Island. Over decades, vegetation overtook whatever structures existed, and today the island is essentially a self-willed woodland surrounded by tidal water, home to nesting birds and dense undergrowth.
Because the island is closed to the public and owned by the city, most people experience South Brother Island visually, from kayaks on the river or from the shores of Randalls and Wards Islands. The surrounding waters attract anglers and paddlers, and the island itself is a recognized urban wildlife sanctuary. For anyone drawn to New York's stranger, quieter edges, South Brother Island offers a compelling reminder that wildness persists even at the heart of one of the world's largest cities.
Visit the shoreline across from the island on a clear morning to catch the best light over the East River and take in the full silhouette of both Brother islands.
Bring binoculars if you're viewing from the Bronx waterfront — wading birds and cormorants are frequently spotted near the island's edges.
Pair a visit to the area with a walk across to Randalls and Wards Islands, which offer public green space and waterfront paths nearby.
Check tide charts before heading to the waterfront; lower tides expose more of the rocky shoreline and improve wildlife viewing angles.
Photograph the island from the Hell Gate area for a composition that layers the island, the river, and the historic bridge arch behind it.
