Everyone loves a trip to the beach. The gentle kiss of the Sun on your skin, the fresh sea‑breeze ticking through the air, the soft grains of sand slipping between your toes, the shimmering waves, the surprising chunks of ice, and even the occasional hot spring—all combine to make a perfect holiday, and some beaches take these wonders to a whole new level.
Why These 10 Strangest Beaches Capture Our Imagination
10 Hidden Beach
Algar de Benagil, perched on Portugal’s famed Algarve coast, hides a secret that only the curious discover. From the cliff‑top you can hear the roar of waves, yet you won’t know where the sound originates until you spot a fenced‑off opening in the rock face. Peering down, you’ll find a secluded stretch of sand tucked beneath a natural roof.
This grotto was carved out over centuries by relentless tides, leaving an arched cavern with a sunlit aperture that pours daylight onto the hidden shoreline. The only way to reach this tiny beach is by sea, so you’ll need to brave the surf and slip between the guarding rocks to set foot on this magical cove.
9 Black Sand And Chunks Of Ice
Iceland’s volcanic heart creates beaches of deep, midnight‑black sand, but the real spectacle lies at Jökulsárlón Glacier Lagoon, where ebony grains are speckled with crystal‑clear ice shards.
The lagoon, linked to the ocean by Iceland’s shortest river—just 1,500 metres long—formed in the mid‑1930s as the Breiðamerkurjökull glacier retreated. The glacier continuously calves massive, diamond‑like ice blocks that drift onto the black‑sand shore, while the sand itself is the pulverised remnants of volcanic rock, ground down by the glacier’s immense weight.
8 Hot Water Beach
Most beachgoers bring buckets and spades for sandcastles, but on New Zealand’s Coromandel Peninsula visitors wield their tools to dig personal hot‑water spas.
When the tide recedes, bubbling water surfaces from the sand—heated by an underground river warmed by geothermal activity. This literal namesake, Hot Water Beach, offers a natural sauna right at the shoreline.
As soon as low tide arrives, people flock with rented spades, carving shallow pools that fill with the steaming water while the cold sea pulls back. The result is a temporary spa where you can soak before the incoming tide washes the pits away, resetting the beach for the next batch of dip‑seekers.
7 Bioluminescent Beaches
Bioluminescence turns ordinary sand into a star‑studded carpet when certain plankton and algae emit light after being disturbed. This natural glow only appears under specific conditions, lighting up entire shorelines.
For predictable displays, head to Mosquito Bay in Puerto Rico, which looks drab by day but erupts in blue‑white sparks at night as tiny dinoflagellates flash when swimmers move through them. In the Maldives, low‑moon evenings coax larger crustaceans to emit a soft blue glow, dotting the sand with luminous specks. Some organisms also shine under pressure, so walking across a bioluminescent beach can leave a trail of glowing footprints.
6 An Inland Beach
Most beaches hug the sea, but Spain’s Gulpiyuri defies that rule, sitting a mere 100 metres from the ocean yet isolated by towering cliffs.
The tiny inlet becomes tidal thanks to a network of hidden caves and channels that connect it to the distant sea. Formed during the last Ice Age, Gulpiyuri—meaning “Circle of Water”—is often called the world’s smallest beach. Visitors can wade in knee‑deep water at low tide, while at high tide the tiny basin fills, offering a surprising splash of seawater far inland.
5 The Disappearing Sea
Low tide usually reveals a broader stretch of sand, but at India’s Chandipur the ocean vanishes entirely, exposing a massive dry seabed.
The coastline’s unusually flat profile allows the sea to retreat up to five kilometres during each low tide. Locals and tourists seize the opportunity to walk, cycle, or even drive across the exposed floor, spotting abundant red crabs and other marine life stranded until the water returns. Timing is crucial—miss the tide, and you could find yourself stranded kilometers from the shore.
4 Shell Beach
While most beachcombers hunt for seashells, Australia’s Shell Beach offers a different treasure: a 70‑kilometre expanse blanketed in layers of cockle shells up to ten metres deep.
Over millennia, trillions of shells have accumulated, forming a massive shell mound that slowly weathers into finer sand. Historically, locals harvested the shells for building material, but today the site is a World Heritage destination, and its hypersaline waters make floating a breeze.
3 Glass Beach
Broken glass is rarely a welcome sight on a shoreline, yet Fort Bragg, California, boasts a beach glittering with sea‑polished glass pebbles.
Decades of dumping unwanted items—including cars—left glass as the only lasting debris. Waves tumbled the shards into smooth, colorful stones that now line the shore. The beach is protected by law, and visitors may not remove the glass. Similar phenomena appear in places like Russia’s Ussuri Bay, where industrial waste created a vivid sea‑glass shoreline.
2 Parrotfish Poop
Imagine strolling across a pristine white beach, the sand slipping through your fingers, and realizing its origin is fish excrement.
Parrotfish graze on coral algae, scraping off calcium carbonate with their beaks. The material passes through their throats, where it’s ground into fine sand before being expelled. A single parrotfish can generate up to 360 kilograms of sand each year, and over centuries, countless fish have turned reefs into the powdery white beaches we adore.
1 Dragon Egg Beach
New Zealand’s dramatic landscapes have filmed fantasy epics, and Dragon Egg Beach lives up to its mythic name with giant, egg‑shaped boulders scattered along Koekohe’s shore.
These Moeraki boulders formed 60 million years ago as concretions of mud, clay, and calcite deep underground. Over time, they were uncovered by erosion, rolling down cliffs onto the beach, each bearing cracks that give the impression of hatching eggs.
According to Māori legend, the stones are the remnants of a wrecked canoe: the hull became the surrounding reef, while the baskets and gourds tossed overboard turned into the massive boulders. The beach remains a popular tourist spot, celebrated for its otherworldly appearance.
