The historic island, which is located in Plymouth Sound, has been closed to the public since 1989. An extra tour date has now been added.
Drake’s Island was put up for sale for £6million in October last year.
Plans for a multimillion-pound re-development of Drake's Island in Plymouth Sound have been approved.
A row about a colony of protected birds could ruin plans for a £10 million hotel on Drake's Island.
The area is home to a colony of Egrets - a white coloured bird similar to a heron.
A report to Plymouth City Council's planning committee has found the egrets would be disturbed if the hotel is built.
Councillors are expected to make a decision this afternoon.
