Silver Sands State Park

A coastal boardwalk crosses restored dunes and marsh while Charles Island sits offshore, reachable only under narrow and hazardous tidal conditions.

Silver Sands links beach, tidal wetland, dunes, and a long boardwalk to Walnut Beach. Charles Island anchors the view and bird habitat offshore. The exposed sandbar may appear at low tide, but rapidly returning water and strong currents make it fundamentally different from a marked park trail.

Enjoy the island from shore unless tide tables, official guidance, weather, and personal ability all support the crossing; rescue calls are common. Summer parking and swimming conditions change, and parts of the beach may close for nesting birds. The boardwalk offers the clearest low-impact route through restored habitat.

Quick guide

Use the boardwalk
See marsh and dune restoration without trampling vegetation.
Respect the bar
Treat the Charles Island crossing as tidal water, not a path.

Know before you go

Check official conditions
Do not rely on seeing other people on the sandbar.
Stay with habitat
Use boardwalk overlooks for marsh and shorebird views.
Read closures
Nesting areas and storm damage can change beach access.
Leave before dusk
Tides and fading light compound navigation risk.

Good to know

People become stranded on the Charles Island sandbar when water returns across uneven ground. A tide prediction is not a guarantee; avoid the crossing when official conditions, weather, or timing are uncertain.
