Know before you go
Water-Only Landmarks
Many iconic sites like Boldt Castle have no bridge access and require third-party shuttles. Verify shuttle return times as late-day service is limited.
Seasonal Availability
Most attractions close from November to April due to river icing. Late June is the transition into full daily operations for all charters.
Marine and Road Supply
Standard fuel is readily available in Alexandria Bay and Clayton. Boaters should identify marinas with marine-grade fuel before entering the remote island channels.
Border Connectivity
Cell signals may frequently switch to Canadian towers near the border. Check roaming settings to avoid unexpected international data charges while on the water.
Mainland Launch Points
Public parking in Clayton is concentrated near the museum and waterfront. Peak summer weekends see lots fill quickly near the Alexandria Bay tour docks.

Access to Heart Island and Dark Island is restricted to operating seasons, typically mid-May through October. While no park entry permit is required, boat tour tickets and castle admission are separate costs and often sell out during summer weekends. State park camping at Wellesley Island can book out nine months in advance, requiring an official New York State Parks check.
