Know Before You Go: Tide-related Flooding

During new and full moon high tides and storm events, the dune area and marsh will flood, limiting access to the beach. During these tides, sea water will wash over the creek’s bank and flood the sandy path that leads from the board walk. Flooding of this type can occur a few times per month, especially during the spring and fall. If going to the beach is an important part of your visit, it is suggested that you check a tides table against the moon phase. If high tide is predicted during your time of visit and you are visiting close to a new or full moon during the spring or fall, you should plan on visiting another day, as the path may be flooded or closed. There is no alternative route to the beach.

Dune grass is an important part of the shore ecosystem as it helps prevent erosion and provides cover to a variety of animals that call the marsh and dune home. Though salt grass can survive in the harsh environment of saltwater, direct sun, and poor soil, it is susceptible to damage from human impacts. During your visit to Sagamore Hill's beach area, you can help protect dune grass by staying on trail and out of the dune area completely.
