Passengers on the ferry to Grímsey Island, located on the Arctic Circle north of Iceland, in 2012 were twice as many as in 2007.
A total of 6,535 people traveled to Grímsey last year, compared to 3,088 in 2007, according to visir.is.
The ferry, which has a capacity of 108 per trip, sails year round between Dalvík, on the northern coast of Iceland, and Grímsey. Foreign visitors make up the majority of passengers in six months of the year.
In addition to ferry passengers, four cruise ships are scheduled to travel to Grímsey next summer.
The number of foreign visitors traveling to the island by plane has also increased.
