Where the River Meets the Sea
Popham Beach State Park sits at the tip of the Phippsburg peninsula, where the Kennebec River empties into the Atlantic. It is one of the few true sandy beaches on the Maine coast, and at low tide it expands into a vast expanse of firm, flat sand that stretches hundreds of yards in every direction. The beach faces south, catching sun from morning through late afternoon, and the combination of river current and ocean tide creates a landscape that changes by the hour.
The park is 14 miles south of Bath, at the end of Route 209. That drive through Phippsburg is part of the experience: a winding two-lane road past old farmhouses, stone walls, and glimpses of the river. The peninsula narrows as you go, and by the time you reach the park, the ocean feels inevitable.
The Beach
At low tide, Popham Beach is enormous. Sandbars emerge between the mainland beach and Fox Islands, and you can walk across the exposed sand to the islands during the lowest tides. The tidal pools on these sandbars hold small crabs, periwinkles, sea stars, and anemones. Kids can spend hours exploring them.
The sand is fine-grained and hard-packed at the waterline, good for walking. Higher up, it softens into deeper, dry sand where people spread blankets and set up chairs. The beach runs roughly a mile in length, with rocky outcrops at both ends.
The intersection of river and ocean currents creates strong and unpredictable water movement at Popham. Swimming is permitted, but pay close attention to the outgoing tide. The current near the river channel can pull swimmers seaward quickly. Swim parallel to shore if caught in a current, and watch children closely in the water.
The water temperature ranges from about 50F in June to the upper 50s in August. Colder than southern Maine beaches because the Kennebec River carries cold inland water into the mix. Most visitors wade and splash rather than sustained swimming.
Time your visit around the tides. Low tide exposes the sandbars and tidal pools, which is the best experience at Popham. Check the tide tables for the Kennebec River entrance before you go. Arrive two hours before low tide to catch the full reveal.
Fort Popham
Fort Popham, a semicircular granite fortification at the mouth of the Kennebec, sits just outside the state park boundary. Construction began in 1861 during the Civil War but was never completed. The walls are thick, the archways are impressive, and you can walk through the interior chambers and climb to the upper level for views of the river, Seguin Island, and the open ocean.
The fort is free to visit and open during daylight hours in summer. It is a 5-minute drive from the state park (or a longer walk along the beach at low tide).
Near Fort Popham, a small fishing pier and the Spinney’s Restaurant provide a classic Maine coast lunch stop. Lobster rolls, fried clams, and ocean views.
Seguin Island
Seguin Island sits about two miles offshore, visible from the beach. The Seguin Island Light, first established in 1795 and rebuilt in 1857, is the highest lighthouse in Maine at 180 feet above sea level. The island is maintained by the Friends of Seguin Island and is accessible by private boat in summer.
Practical Details
Popham Beach State Park is open year-round, 9 AM to sunset. Admission is per person: $6 for Maine residents, $8 for non-residents. Maine residents 65 and older are free. Children under 5 are free.
Dogs are not allowed on the beach from April 1 through September 30. From October through March, dogs are welcome on leash. The off-season is a fine time to visit with a dog: fewer people, wide-open sand, and dramatic winter waves.
The parking lot holds a limited number of cars. On hot summer weekends, the lot fills by late morning and the gate closes to new arrivals. Come early.
Late September and early October are some of the best times to visit Popham. The summer crowds are gone, the water is actually at its warmest, and the angle of the light turns the sand and fort golden in the afternoon. Dogs are allowed after October 1.
Nearby: Hermit Island
Hermit Island, a private campground on a small peninsula just south of Popham Beach, offers some of the most sought-after oceanfront campsites in Maine. Sites sit on rocky headlands and tucked into spruce groves overlooking the ocean. Reservations open in January and popular sites sell out within hours.

FAQ
Can you walk to Fox Islands at Popham Beach?
At very low tides, the sandbars between the beach and Fox Islands are exposed and you can walk across. Check tide charts carefully and give yourself time to return before the tide comes in. The water rises quickly.
Are dogs allowed at Popham Beach?
Dogs are banned from April 1 through September 30. From October through March, dogs are welcome on leash. Off-season visits with dogs are excellent, with wide-open sand and few people.
How much does Popham Beach cost?
Admission is per person: $6 for Maine residents, $8 for non-residents. Children under 5 and Maine residents 65 and older are free. Cash or check at the gate.
Is swimming safe at Popham Beach?
Swimming is allowed but requires caution. The Kennebec River current meets ocean tides, creating unpredictable water movement. Swim near the center of the beach, avoid the river channel at the east end, and watch for rip currents on outgoing tides.
What is the water temperature at Popham Beach?
Ocean water ranges from about 50F in June to the upper 50s in August. The Kennebec River brings cold inland water, keeping temperatures slightly cooler than beaches further south.
