Legend claims the staircase was carved into the cliff in a single night by Aragonese invaders.
The staircase serves as a functional connection between the citadel walls and a natural cave housing a potable water source.
The steps are cut into Bonifacio's characteristic white limestone, which is prone to erosion and requires ongoing stabilization.
The path is extremely narrow, forcing a single-file descent and ascent for all visitors.
The Escalier du Roy d'Aragon is a flight of 187 steps carved directly into the limestone cliffs of Bonifacio, Corsica. Tradition attributes the staircase to the troops of King Alfonso V of Aragon during the 1420 siege of the city, though geological evidence suggests it may have been cut earlier by monks to access a freshwater spring. The path descends approximately 60 meters from the upper town plateau to a narrow cliffside trail just above sea level. The trail follows the coastline for a short distance before reaching the site of a natural spring cave. The stairs are angled at approximately 45 degrees, making the ascent physically demanding. Visitors must walk along the cliff face exposed to the Mediterranean Sea. The site is a primary element of Bonifacio's historical defensive landscape.

Wear sturdy, closed-toe athletic shoes with good grip, as the limestone steps can be slippery.
Avoid this site if you have a fear of heights or limited mobility, as the stairs are steep and lack extensive safety enclosures.
Bring water, as there are no facilities available once you begin the descent.
Attempting the climb during high winds or rain, as the cliffside path becomes hazardous.
May be closed during periods of extreme high winds or inclement weather for safety reasons.
Maintain a steady pace to avoid congestion on the narrow stairs; do not stop mid-staircase to take photos.
