The Algarve Cala trail was the ultimate reward for my trail adventures along the Portuguese coastline. Earlier that morning, I visited the inland pilgrimage town of Loulé. After six days, I already had over 100 kilometres of running, hiking, scrambling, and climbing over rugged sea cliffs in my legs. But neither Cala nor Loulé was something I could bear to miss.
Cala Trail: Imagine walking across the undulating countryside of the inland Algarve, wrapped in the scent of wild thyme and sun-baked grass. The ocean is nowhere in sight—you are easily 200 metres from the open coast. And suddenly, right in front of you, a massive crater opens in the earth. Far below on the floor, fine white sand glows and turquoise water sparkles.
Welcome to Algarve Cala (Praia da Cala)—one of the most jaw-dropping and best-kept secret beaches in all of Portugal.
How Does an Inland Beach Form?
Praia da Cala is an example of a geological phenomenon known as an alpondra or sinkhole.
Over millions of years, subterranean seawater carved away the soft limestone and sandstone bed of the inland terrain until the ceiling of a massive sea cave finally collapsed. This formed an enormous rock crater connected to the open ocean via a natural underground tunnel. Fine marine sand washed into the basin, creating a perfect, fully sheltered beach surrounded by sheer, 30-metre-high vertical walls.
Algarve Cala Trail: When Even the Locals Shake Their Heads
No asphalt roads lead to this beach, nor will you find brown tourist signs or parking facilities. That is precisely why Algarve Cala has retained its raw, untouched isolation.
Yet the adventure didn’t end there. As if the Algarve wanted to reward me one last time, the trail led me across six distinct beaches, each boasting a completely unique character and geological composition.
Today, I paused for a second time to consider the rocky reefs I was scrambling over. This trek was strictly for strong nerves. Time and again, I carefully weighed where to place my foot—or whether to take the step at all. Definitely not an excursion for all-inclusive resort guests in high heels or casual strollers with toddlers.
Clementines and GPX Coordinates for a Local
Just like every other day, I stopped by a local roadside grower and bought 6 kilograms of fresh clementines for an unbelievable 5 euros. Sweeter juice than from these citrus fruits simply does not exist.
With a backpack loaded with fresh fruit and two cold beers, I pushed through the scrubland terrain to the edge of the rock fissures and cliffs surrounding Algarve Cala. The 100-metre descent along narrow rock ledges demands sturdy footwear, caution, and a sure foot.
The reward? Beaches without a single human soul. No sun loungers, no bars—just sacred silence, the subterranean rumble of water surging through the rock tunnel, and soaring cliff walls shielding you from the wind. Just take care not to get trapped like that fellow watching the swallows.
The Tale of Rabbit Beach and the Trapped Tourist
The name of Praia da Coelha translates literally to “Female Rabbit Beach”. Centuries ago, thousands of wild rabbits populated the pine-framed cliffs here. Whenever local fishermen headed down to the sea, rabbits would literally dart between their feet.
Just a 15-minute walk west along the cliffs lies the hidden cove of Praia do Ninho de Andorinha (Swallow’s Nest Beach). It is a massive rock crater enclosing a tiny sandy beach inside the mainland, connected to the sea via a natural tunnel. A few years ago, a German tourist looking for a shortcut scrambled down the rock ledge at low tide, completely forgetting that the tide rolls back in. The rising water submerged the entire tunnel and access route, trapping him inside the rock crater. Search and rescue crews had to winch him out by helicopter. When asked what on earth he had been doing down there for four hours, he replied: “I was taking selfies and watching the swallows.”
When I showed my photos from the Cala trail to a local Portuguese gentleman later that evening, he stared at the screen in disbelief: “Is this really here in the Algarve? Where on earth is this, exactly?”
When a local asks you for the GPS coordinates of his own homeland, you know you’ve stumbled upon a true treasure.
From €50,000 to €6,000,000
The Portuguese hold their coastal cliffs in exceptionally high regard. Have you ever paid a fine? Certainly nothing quite like this. Though paying even a draconian sum is arguably far better than plummeting off a cliff face in a car or on a motorbike.
Practical Tips for Exploring Algarve Cala
- Zero Amenities: You will find absolutely nothing on Algarve Cala. All food, ample water, and trash bags must be brought in—and carried out—by you.
- Scramble with Care: The descent path through the rock fissure is not secured with ropes or railings. It demands sturdy shoes (definitely no flip-flops!) and a level head.
- Mobile Reception: Inside the sunken rock crater, mobile signal generally cuts out completely. Embrace the feeling of a total digital detox in the heart of raw nature.
🏖️The Most Beautiful Beaches Around the Cala Trail
A genuine hidden gem! A tiny sandy beach enclosed at the bottom of a deep rock crater (sinkhole) with a natural tunnel leading to the ocean. Reaching it requires a careful scramble down the rocks.
A magnificent cove framed by soaring golden cliffs. It takes its name from a 16th-century watchtower that once stood here to guard the coast against pirate raids from North Africa.
A small, rocky cove surrounded by pines, renowned for its crystal-clear waters. It is home to one of the most famous seafood restaurants in the Algarve, frequented by Portuguese presidents and international celebrities.
One of the most photogenic beaches in all of Portugal. It is dominated by bizarre rock formations like Ponte Pequena (Little Bridge) and Ninho das Andorinhas (Swallow’s Nest) rising straight out of the seabed.
A charming, diminutive cove characterized by three massive rock stacks (Os Três Ursos – The Three Bears) standing just offshore. It is a true paradise for snorkelling and observing marine life.
In contrast to the intimate coves, Galé is a wide, kilometre-long beach where rocky cliffs give way to low, sweeping dunes. Low tide reveals natural rock pools in the sand, ideal for safe bathing.
