Habitats and Wildlife

Located on the South River, which flows into the North River downstream at Fourth Cliff.

Like the North River, the South River is a beautiful tidal estuary where wildlife abounds! Paddling or boating on this estuary allows you to go shellfishing, fishing or just exploring. Downstream there are salt marshes and numerous creeks, host to egrets and blue heron. You might even see a bald eagle!

Soft shell clams, better known as “steamers,” hardshell clams, as well as razor clams can be found in the tidal flats, and can be harvested with a permit. (See this recent update on North River Shellfishing for locations.) The clam flats in both the North and South Rivers are typically open from November 1 to May 31st. If there is a Red Tide, they may close sooner. (In 2023, some areas opened on January 1st and others will open on March 1st.)
