Cape Cod's Best-Kept-Secret Is A Mesmerizing Bioluminescent Beach In Falmouth

Cape Cod is known for some spectacular beaches, and the Massachusetts peninsula has one in particular that is quite special, though not for the reasons you may think. Stony Beach, located in the fun beach town of Falmouth, isn't just a charming little seaside hamlet to splash around in by day. At night, it can also transform into something incredible, as during certain times of the year the water can literally glow.

This is because Stony Beach is one of the top places in the United States to see bioluminescence. For those unfamiliar with the phenomenon, bioluminescence is when any organism creates light thanks to chemical reactions in its body. It's not uncommon to see this reflected in the ocean, where fish, plankton, and jellyfish are just some of the animals that emit a light that appears blue or even green. It's a dazzling site that seems to make the water sparkle at night and Stony Beach is known for its bioluminescent sightings.

Usually noticeable before midnight, according to locals, the bioluminescence found in the shallow waters of Stony Beach is likely due to plankton and the comb jellies that are common to the area. During the summer months, thanks to warm, calm waters, these organisms come closer to shore where it's easy to see their dazzling light display as they are jostled by the waves. Stony Beach faces tranquil Buzzard's Bay, making it the perfect place for bioluminescence to occur.

Stony Beach is located in the charming coastal attraction of Woods Hole, an unincorporated village within Falmouth that is an epicenter of marine biology. This is thanks to its Marine Biological Laboratory and the nation's oldest marine research station, the Woods Hole Laboratory. The Marine Biological Laboratory (MBL) actually owns Stony Beach, which has clear shallow waters that are wonderful for snorkeling during low tide. The calm nature of the water also makes it a favorite place for families to safely enjoy time in the water.

Tucked between two jetties that protect it, this hidden gem is the perfect getaway from some of Cape Cod's more crowded beaches. Lifeguards are on duty seasonally and it's even ADA accessible thanks to the possibility of reserving a beach wheelchair in advance and having it delivered. There is also an outdoor shower and facilities, though the restroom is seasonal and is only a porta potty.

A word of caution about visiting by car — The small parking lot is only open to vehicles with resident stickers during the summer months. However, the beach can be accessed by anyone, so it's best to park elsewhere and arrive on foot. The beach is officially open from dawn until dusk, so take care if coming at night to see the bioluminescence. Visitors report that the MBL has a security guard who patrols the beach occasionally and will ask people to vacate the area, so it's best to proceed with caution. To reach Falmouth and make the journey to Stony Beach, the closest airport is Boston Logan International, which is about a two hour drive from the coastal town.
