10 Spectacular Coastal Rock Formations Around the World
Coastal rock formations endure constant battering from nature. Malta’s Azure Window collapsed in 2017, only eight of the original 12 Apostles remain along Australia’s Great Ocean Road, and New Zealand’s Elephant Rock lost its trunk during a 2016 earthquake.
Yet geology enthusiasts and fans of dramatic seaside landscapes still have much to explore. Discover 10 of the world’s most striking coastal rock formations.
Durdle Door – Dorset, England
This iconic limestone arch on Dorset’s Jurassic Coast resembles a sea serpent sipping from the waves. A beloved natural wonder in England, it draws photographers and beachgoers to the adjacent pebble shore in summer. Its name stems from Old English ‘thirl,’ meaning ‘pierce’ or ‘drill.’ Reach it by parking atop the cliffs and descending, or hiking the one-mile path from Lulworth Cove. Nearby, discover jagged limestone islets dubbed the Bull, Blind Cow, Cow, and Calf.
Yehliu Geopark – Taiwan
Jutting into the East China Sea, Yehliu Geopark features hoodoo formations resembling mushrooms, dragons, and trees—perfect for sci-fi backdrops. These occur when softer sandstone erodes beneath harder volcanic caps, creating slender columns with bulbous tops. Highlights include Elephant Rock, Fairy Shoe, and Queen’s Head, evoking a regal profile. Follow up with fresh seafood at nearby restaurants.
Punakaiki Pancake Rocks – South Island, New Zealand
Along New Zealand’s rugged northwest coast, these layered limestone cliffs—formed 30 million years ago from marine deposits—create an otherworldly scene. During high seas, water surges through blowholes, erupting dramatically. An easy 20-minute loop track provides access. Visit in stormy weather for peak action, and watch for dolphins in the waters below.
Source d’Argent Beach – Seychelles
Massive, sculpted granite boulders frame this powdery beach on La Digue’s southwest coast, evoking ancient elephants. Snorkel in shallow waters amid the rocks for turtles, avoiding sea urchins. Relax with a coconut, gazing at Praslin’s emerald hills. Time your visit for low tide, as high water engulfs the shore.
Arch of Cabo San Lucas – Baja California Sur, Mexico
At Baja’s southern tip, where the Gulf of California meets the Pacific, ‘El Arco’ or ‘Land’s End’ stands unreachable by road. Approach by glass-bottom boat, sunset catamaran, or kayak—mind Pacific swells. Millennia of erosion shaped this arch, home to lively sea lion colonies. Afterward, savor tacos and mezcal in Cabo San Lucas.
The Remarkable Rocks – Kangaroo Island, South Australia
Over 500 million years, Indian Ocean winds and waves sculpted these granite boulders into abstract forms blending mica, quartz, feldspar, and orange lichen. Visit at sunset for a golden glow. Kangaroo Island offers seals, lavender fields, and fairy penguins beyond.
Hopewell Rocks – New Brunswick, Canada
In Bay of Fundy’s dramatic tides, these tree-topped sandstone towers transform: walk the seabed at low tide among Lover’s Arch and Dinosaur Rock; kayak hidden coves at high tide. Shaped by ice and rain, note that even stalwarts like Elephant Rock fell in 2016.
Giant’s Causeway – Northern Ireland
Legend credits giant Fionn mac Cumhaill with building this bridge to Scotland, but 40,000 basalt columns from ancient volcanoes are the true story. A top Northern Ireland attraction off County Antrim, reach it fee-free by 45-minute walk from Bushmills amid Atlantic views.
High Island Cliffs – Hong Kong
Escape Hong Kong’s neon for these towering hexagonal basalt columns from 140-million-year-old lava flows—a UNESCO Geopark. Hike for sea views to jungle islands, then taxi to Sai Kung for seafood.
The Glass Window – Eleuthera, Bahamas
On narrow Eleuthera, the 30-foot-wide Glass Window contrasts calm Caribbean shallows with turbulent Atlantic depths. Climb bluffs for views (carefully on windy days), then soak in Queen’s Baths rock pools.
