Karavolades Stairs, the staircase that links Santorini’s old port to the town of Fira, is currently closed, according to reports by local media.

The closure impacts cruise calls to the Greek Island, which is one of the most popular destinations in the Aegean Sea.

Atlantea reported that the 558-step pathway is blocked due to the collapse of a wall of a private building.

The local news source added that the closure was decided by the Mayor of Fira and will remain in place for the time being.

Cruise passengers arriving in Santorini traditionally disembark at the old port after being transferred by tender boats.

The pier serves as a starting point for excursions to other parts of the island via water, as well as a gateway to Fira, which is located 250 meters above sea level.

To reach the town, which is the largest settlement in Santorini, guests must either use the staircase or a cable car service, as roads for vehicles are not available.

As a result of the Karavolades Stairs closure, cruise passengers with booked shore excursions will now disembark at Santorini’s new port.

According to Business Daily, tenders will transport these guests to Athinios, from which they will be able to board tour buses.

While regulations introduced earlier this year limit the percentage of cruise passengers allowed to use the new port per day, restrictions will be lifted due to the closure.

Business Daily’s report said that the change will remain in force until the Karavolades Stairs are reopened.

In June, local authorities decided to limit the number of passengers in Athinios to 30 percent due to what they called civil protection measures.

Οικονομικός Ταχυδρόμος reported at the time that the Municipal Port Fund of Fira aimed at keeping roads clear for potential emergencies.

Over 25 cruise ships are scheduled to visit Santorini in August, including large vessels from brands such as Royal Caribbean, Princess, Norwegian, P&O and Celebrity.
