San Juan de Gaztelugatxe: what does the audio guide cover?

  1. 01

    Welcome to the Rock of the Castle

    Welcome to one of the most breathtaking sights on the planet, San Juan de Gaztelugatxe. As you stand here, look out toward that jagged islet rising 80 meters above the crashing waves of the Bay of Biscay. The name itself carries a mystery; in the Basque language, it can be translated as The Rock of the Castle or even the Inaccessible Castle. You are currently near the San Pelaio area of Bakio, though the islet itself belongs to the municipality of Bermeo, and it all feels a world away from any city. Feel the salt spray on your skin and listen to the Atlantic wind—this is a place where nature and history have fought for supremacy for over a thousand years. This tiny island is connected to the mainland by a man-made stone bridge that looks as if it were plucked straight from a fantasy novel. Prepare yourself, because you are about to walk a path that has been trodden by pilgrims, pirates, and even legendary kings.

  2. 02

    The Path of Two Hundred and Forty-One Steps

    To reach the top, you must conquer a winding staircase made of exactly 241 stone steps. While some older records mention different counts, modern measurements confirm 241 as the number you will likely find yourself counting under your breath. This is not just a hike; it is an architectural marvel that zigzags across the crag to overcome a steep 100 meter incline. Despite its peaceful appearance today, this rock was once a strategic military stronghold for the Lords of Biscay, serving as a defensive fortress against pirate raids and seafaring invaders during the Middle Ages. In fact, the famous English privateer Sir Francis Drake is said to have attacked this sanctuary in 1596, looting its treasures. As you climb, notice how the stones are worn smooth in the center—each step is a physical memory of the millions of pilgrims who have come here seeking solace or protection.

  3. 03

    The Footprints and the Lucky Bell

    As you reach the final summit, you will find a small church dedicated to Saint John the Baptist. Local legend tells us that the Saint himself reached this peak from the town of Bermeo in just three giant strides. Look closely near the last step, and you may see what is said to be his final footprint—tradition dictates that if you step into it, you will receive protection and good luck. But the most famous tradition here involves the church bell. It is standard custom to pull the rope and ring that bell three times while making a silent wish. This practice was originally intended to ward off evil spirits and protect the local arrantzales—the Basque fishermen—from storms at sea. Even today, you might see fishing boats from Bermeo performing a special ritual of three turns toward the island before heading out for the tuna season, asking the Saint for a safe return.

  4. 04

    A Cinematic Fortress in a Living Sanctuary

    For many, this location is instantly recognizable as Dragonstone from the television series Game of Thrones. While the massive castle you saw on screen was digitally added, the winding stairs and the bridge were the actual stage for the Mother of Dragons and her world. However, the reality is even more scientifically fascinating. This island and the neighboring rock of Aketxe form a Protected Biotope, a sanctuary for rare marine birds like the European storm petrel and the shag. If you look down at the waves, you are looking into a vibrant underwater ecosystem where a submerged image of the Virgin of Begona was placed in 1963 as a patron for divers. It is a delicate balance of pop culture fame and biological preservation. Because of this popularity, remember that you must reserve a free ticket online in advance during the high season, as access is strictly capped to protect this fragile environment.

  5. 05

    The Infinite Horizon

    As you pause at the top, take a moment to look toward Cape Matxitxako to the east and the town of Bakio to the west. The coastline here is a living laboratory of geology, where the relentless Atlantic has carved out sea caves and arches over millions of years. You might feel the weight of history in your legs after that climb, but let your curiosity lead you further. Perhaps you will wander into Bermeo to see the fishing harbor, or toward the nearby Urdaibai Biosphere Reserve just a short drive away. The path back may be downward, but the perspective you have gained from this ancient crag will stay with you. There are still many small paths and hidden viewpoints around the Urizarreta checkpoint waiting to be discovered—each one offering a slightly different angle on this impossible castle.
