The Aquinnah Cliffs, formerly known as Gay Head, is one of Martha's Vineyard's most-visited tourist spots, with bus and bike tours congesting the paved roads in the peak summer season. But the epic clay cliffs, which were carved by glaciers millions of years ago, are worth the trek. Visitors can explore the lower beach paths to see the cliffs up close and stretch along the sands at Moshup Beach. Or take the upper trails to the top of the cliffs to catch a glimpse of Gay Head Light and nearby Elizabeth Islands.

The Gay Head Cliffs are a national landmark. The beautiful, colorful layers of clay make up the cliffs. It has been said that fossil bones of whales, camels, and wild horses have been found in the cliff layers. The Gay Head Lighthouse is perched atop the cliffs. It is the only working lighthouse on Martha’s Vineyard. The Gay Head lighthouse was built in 1856. The lighthouse is open for tours and several events have been located on its grounds including weddings.

You'll find the Aquinnah Cliffs off of State Road on the southwestern tip of the island, to the west of Gay Head Light. There's parking available (for $15 in the summer), but the lot fills up fast. Most visit Aquinnah by bike or bus.
