A fundamental review of all operations, including safety, is to be carried out on Skellig Michael off the Kerry coast.
Dr Martin Mansergh, Minister with responsibility for the Office of Public Works, made his comments following the second death in less than five months of a visitor to the Skellig rock.
He said the issue of access, fencing and the number of guides on site will be part of the review.
Dr Mansergh also said that boat operators and emergency services will be consulted for their input into measures required to make the island safer.
Yesterday, a woman died after a fall on the island.
The 57-year-old is thought to be from the US.
She sustained serious head injuries after she fell while walking with her husband.
