Bannerman Island Cruise & Walking Tour: Pollepel Island, Grotto Access from Beacon

On a 2.5-hour voyage from Beacon, New York, the Weekday Special — Bannerman Island Cruise & Walking Tour offers a compact, potent taste of Hudson River history and shoreline drama. Launching from 2 Red Flynn Drive, passengers board the RV Estuary Steward for a short cruise to Pollepel Island, where the crumbling silhouette of Bannerman Castle rises against the Hudson Highlands. The outing combines guided narration, a shore walk through gardens and ruins, and in 2026 a rare admission to a previously closed architectural feature known locally as 'The Grotto'. Pollepel Island’s most striking features are the red sandstone-and-concrete ruins of Bannerman Castle, the compact gardens around its foundation, and the narrow island promontory that skims close to the river’s channel. The tour is offered in partnership with Bannerman Castle Trust Inc. and the New York State Office of Parks, Recreation, and Historic Preservation; proceeds support ongoing preservation and public access. Tours run rain or shine, and the itinerary includes a 72-step climb from the dock to the trailhead plus uneven terrain on the walking portion, so plan accordingly. For photographers and history buffs the island rewards curiosity: the castle’s ruined walls frame long views downriver to the Hudson Highlands, while masonry details and the newly available Grotto reveal surprising craft and eccentric design. Natural highlights include river-facing ledges, the island’s modest gardens, and seasonal birdlife that often rides the thermals along the cliffs. Staff-led interpretation fills in the story of the site and the stewardship work that keeps the island open to visitors. Logistics are simple but specific: check in at the floating dock at 2 Red Flynn Drive and arrive 30 minutes before departure. Strollers and wheelchairs cannot be accommodated and only service dogs as defined by the ADA are permitted on the island. Food and drinks aren’t included, though snacks and souvenirs may be available on site. Wednesday and Thursday weekday tours in summer carry a special rate and include the Grotto visit, a rare chance to see a space closed for decades. This trip is an efficient, intimate way to connect with the Hudson River’s military and maritime past while supporting ongoing conservation. Whether you come for the ruins, the river views, or the hidden architectural feature opening this season, the Bannerman Island cruise-and-walk pairs a short, scenic boat ride with a layered, walkable history lesson that remains approachable for families and active day trippers. Guides point out geological cues and local conservation challenges, and small-group sizes keep visits low-impact; bring binoculars for osprey and other river birds, wear grippy shoes for the uneven stone, and expect brisk river breezes that can make a warm day feel cool.
