A hundred million years of clay, sand and lignite in one wall. The colors shift with the light and the season.

Aquinnah Cliffs: 100-million-year-old clay formations, Gay Head Lighthouse, Moshup Beach, and Wampanoag heritage on MV.

The Aquinnah Cliffs rise roughly 130 to 150 feet above the Atlantic at Martha's Vineyard's western tip, a mile-long wall of multicolored clay that ranks among the most dramatic coastal formations on the East Coast. Sacred to the Wampanoag people for at least 10,000 years, designated a National Natural Landmark in 1975, and home to one of New England's most historic lighthouses, the cliffs are geology, Wampanoag history and the island's best-known view in one place. For a broader look at the town itself, see our Aquinnah town guide.

100 Million Years in the Cliff Face

The cliffs tell a two-act geological story. Act one played out during the Late Cretaceous period, roughly 100 to 65 million years ago, when this area was a subtropical river delta emptying into the young Atlantic. Layer upon layer of clay, sand, and gravel accumulated in coastal-plain environments: beaches, estuaries, marshes, and lagoons. Additional Miocene-era greensand layers (5–23 million years old) were deposited later in a shallow sea.

Act two arrived with the Wisconsinan glaciation about 21,000 years ago. The Laurentide ice sheet advanced to its southernmost extent along what is now Martha's Vineyard and Nantucket, pushing the buried Cretaceous sediments forward and upward. Some layers now stand nearly vertical, tilted about 80 degrees. The cliffs sit on the island's terminal moraine, the ridge left at the glacier's farthest reach. The same geological system runs along the south shore to the cliffs at Lucy Vincent Beach in Chilmark.

Each color has a mineral signature: red and maroon from iron oxide (hematite). Orange and brown from limonite and goethite. White bands are kaolin clay. Black streaks are lignite, low-grade coal preserving 90-million-year-old charcoal from ancient conifer forests. Green layers are glauconite, an iron potassium mineral forming the Miocene greensand. Purple hues likely result from iron oxide mixtures in varying oxidation states. Fossils found here include camel teeth, megalodon shark teeth, and whale bones.

The cliffs erode at approximately 1.8 to 2 feet per year from wave action and groundwater seepage. Climbing the cliffs or removing clay is strictly illegal, enforced by Wampanoag Conservation Rangers to protect this fragile National Natural Landmark.

The clay was an economy before it was a view. Nineteenth-century New England potters wanted Vineyard clay because it was the only stoneware-grade clay in the region, and Gay Head families dug it and carried it by boat to the mainland kilns; in 1893 the newly incorporated town leased the cliffs to the Gay Head Clay Company for 500 dollars a year to feed brickworks. Tourists did the rest. Alfred Eisenstaedt, who photographed the cliffs every August from 1937, wrote in 1980 that most of the red clay he had known in the 1960s had either fallen into the sea or grassed over, and that a good part of the damage was people climbing and digging; he was known to shout at children with shovels. The ban on climbing and taking clay that the Tribe and the town enforce today came out of exactly that.

The Legend of Moshup

In Wampanoag tradition, the cliffs are inseparable from Moshup (also spelled Maushop), the giant who is the central figure of the Tribe's oldest stories. The Tribe's own telling describes Moshup as "a benevolent being of gigantic frame and supernatural power" who created Martha's Vineyard itself. Weary from a journey across the mainland, Moshup dragged his foot heavily through the mud; the ocean gradually widened the track, separating the island from the mainland.

From a den near the Aquinnah Cliffs, Moshup would wade into the ocean, seize a whale, and fling it against the cliffs to kill it before cooking it over a perpetual fire. "The blood from these whales stained the clay banks of the Cliffs dark red," the Tribe recounts. To reach whales in deeper water, Moshup threw stones into the sea, creating the underwater reef known as Devil's Bridge, infamous for shipwrecks. He also created Nantucket by emptying his pipe ashes into the ocean. Moshup Beach, at the base of the cliffs, is named for him. The Tribe has staged the Legends of Moshup pageant on tribal land in recent summers; check the Tribe's calendar for the current year.

From Gay Head to Aquinnah

The town changed its name from Gay Head to Aquinnah at an annual town meeting in May 1997, by a vote of 79 to 76, a margin of just three votes. (An earlier attempt in 1991 had failed 89-36.) The Massachusetts legislature passed enabling legislation, and Acting Governor Paul Cellucci signed it into law in May 1998. The effort was led by Wampanoag leader Carl Widdiss, who cited "the importance of retaining the town's Native American heritage."

"Aquinnah" is the original Wampanoag name, meaning "land under the hill", the hill believed to be Peaked Hill in Chilmark. "Gay Head" was the name English colonists gave the headland in the 1600s for the bright ("gay") colors of the cliffs. The lighthouse remains officially "Gay Head Light" on the National Register of Historic Places, and the tribe's federal name is the Wampanoag Tribe of Gay Head (Aquinnah), recognized on April 10, 1987, one of only two federally recognized Wampanoag tribes. Under the 1987 Settlement Act, approximately 485 acres were taken into trust, including the cliffs. Today roughly 1,364 citizens are enrolled, about 300 living on-island.

Gay Head Lighthouse

The lighthouse traces back to 1799, when a 47-foot octagonal wooden tower was built under a contract approved by President John Adams: the first lighthouse on Martha's Vineyard. The current 51-foot brick tower was completed in 1856, built by contractor Caleb King using bricks made from the cliffs' own clay. A First-Order Fresnel lens from France was installed with 1,008 hand-made crystal prisms. The lens was removed in 1952 and now resides at the Martha's Vineyard Museum in Vineyard Haven.

In May 2015, the lighthouse was moved 129 feet inland over three days after erosion brought the cliff edge dangerously close. The $3–3.5 million project was managed by International Chimney Corporation. The deed was transferred from the Coast Guard to the Town of Aquinnah for $1.

The lighthouse was closed for all of 2025 for a $1.4 million restoration funded primarily by offshore wind company Ørsted (~$1 million), a state tourism grant, and Community Preservation Act funds. A new LED beacon was installed, restoring the historic flash pattern of three whites followed by a red (established 1874). It reopened Memorial Day weekend 2026. Hours: 10 AM–4 PM, daily through Labor Day and four days a week into the fall. Admission: $6 (ages 13+), free for children 12 and under, veterans, and Aquinnah residents. Climb 55 steps for a view from 170 feet above sea level.

Moshup Beach and Practical Tips

The Gay Head Cliffs sign at the overlook. The beach below is a walk down Moshup Trail.

A 10-minute walk down a sandy dune path from the parking lot leads to Moshup Beach, roughly half a mile of shoreline beneath the cliffs. No lifeguards are on duty. The beach faces southwest with strong surf and currents, best for confident ocean swimmers. Portable restrooms sit at the beach entrance. Photographers should read our photo spots guide for the best hour at the cliffs and the rules on the face.

The section closer to the cliffs (to the right when facing the water) has a longstanding clothing-optional tradition. A posted sign reads "Beyond this point you may encounter nude sunbathing." Nudity is technically illegal under Massachusetts law but has been unofficially tolerated for decades. In 1991, residents rejected a bylaw that would have authorized arrests.

Parking: The clifftop overlook has free 30-minute parking. For the beach, the Moshup Beach lot charges approximately $35/day (credit card only, no cash). The lot holds about 90 vehicles and fills by 10:30 AM on summer weekends. Aquinnah residents can buy seasonal permits. Verify current rates: (508) 645-2300.

The most dramatic view of the cliffs, looking up at the full multicolored face, requires walking down to the beach. The clifftop overlook shows them at a distance. Sunset is prime time as the western-facing cliffs glow in golden light.

Clifftop Shops, Food and Cultural Center

The 10–15 businesses at Aquinnah Circle are virtually all Wampanoag family-owned, operating on town-leased land, a genuine Indigenous cultural district. Cliffhangers is the main food spot, serving lobster rolls, clam chowder, and ice cream with occasional Thursday-evening live music. Gift shops include Stony Creek Gifts (85+ years, wampum jewelry), Hatmarcha Gifts (handmade beadwork), and several others selling Native crafts. Shops open roughly Memorial Day through Columbus Day, closing around 5 PM.

Note: The Aquinnah Shop Restaurant, a clifftop institution since 1948, has been closed since approximately 2022. In 2023, the Native Land Conservancy purchased the property for $2 million to return it to Wampanoag ownership. No confirmed reopening as of 2026.

On the way to the cliffs, stop at Orange Peel Bakery (22 State Road, Aquinnah), owned by Wampanoag leader Juli Vanderhoop, featuring a 20,000-pound wood-fired beehive oven producing artisanal bread, pastries, and Thursday-night pizza in season. Partly on an honor system. The bakery's website showed a closed notice in early September 2026, so check before you go.

The Aquinnah Cultural Center at the Edwin D. Vanderhoop Homestead (35 Aquinnah Circle, built 1890) offers exhibits on Wampanoag history, guided walking tours, and art installations. Open for the 2026 season June 16 to October 21, Tuesday through Sunday 11 AM–4 PM; admission $10 adults, $8 seniors and students, $6 ages 7–17, free under 7 and for tribal members. Closed September 12 and 13 for the Powwow. A Heritage Exhibit Kiosk outside provides information when closed.

Getting to Aquinnah

VTA Bus Route #5 (via South Road through West Tisbury and Chilmark) serves the cliffs approximately once per hour in summer, currently free to ride through June 30, 2027 under the fare-free initiative. The trip from Vineyard Haven requires a transfer at West Tisbury Town Hall and takes about an hour. Check the VTA schedule for current times.

Driving: ~17 miles/30 minutes from Vineyard Haven. ~20 miles/35–40 minutes from Oak Bluffs. ~19 miles/30–40 minutes from Edgartown. The scenic Moshup Trail hugs the coast near Aquinnah.

Biking is possible but challenging: 17 hilly miles from Vineyard Haven on narrow roads with no dedicated bike path. Recommended for fit cyclists only. A popular strategy: take the bus up and bike back (largely downhill). See our bike routes guide for details.

Most visitors spend 1–2 hours at the cliffs for the overlook, shops, and lighthouse. Adding beach time extends a visit to a half day. The Jaws billboard scene was filmed at 35 Aquinnah Circle with the lighthouse visible behind. See our complete Jaws filming locations guide.
