Tavia's island is an unofficial name given to the uncharted isle claimed by Tavia the legendary fisherwoman. Players may visit the island by speaking to Quartermaster Gully with a red uncharted island map. While Tavia is not on the island when a player visits it, players will be able to find a stack of books containing Tavia's Fishing Notes along with Tavia's fishing rod.
On the front door of the house, there is a note that reads "GONE FISHING -Tavia", with a mysterious rod standing against the front post. The front door can be knocked on but nobody will answer.
Unlike other islands in the Uncharted Isles, this island cannot be claimed with a claim island flag. Attempting to plant a flag will prompt the message "You cannot claim this particular island."
