Bordering the south side of the mouth of the Kennebec River, Popham Beach State Park is truly one of Maine’s rare geologic landforms that feature a long stretch of sand beach. Sunbathers relaxing on Popham’s sands can see Fox and Wood islands offshore, and the Kennebec and Morse rivers border each end of the beach. Visitors can walk to Fox Island at low tide, but are warned to pay attention to the rising tides not to get marooned.
