Sea Life Loch Lomond is offering free entry for children who come dressed as their favourite book characters or carry their favourite book.
Children aged between two and 15 years, dressed in book-themed costumes, accompanied by a fully paying adult will receive free entry from March 7 until 10.
The adult ticket must be pre-booked by visiting merlinmagic.biz/wbd/.
Nick Brigden, head of UK Brand Partnerships at Merlin Entertainments, said: "We are very much looking forward to sharks, Queens, bunnies and dragons visiting us across World Book Day weekend.
"If your children love a great read, we’re hoping to inspire their future reading through our attractions.
"World Book Day provides us with the perfect opportunity to ignite the spark of imagination in the hearts of children, encouraging them to explore the wonders of reading."
Cassie Chadderton, chief executive of World Book Day, said: "It’s wonderful to partner with some of the top UK attractions to celebrate the enjoyment of reading.
"We hope these fabulous days out in amazing spaces such as SEA LIFE inspire families and children to have fun with books, so that many more can grow up with the life-changing benefits of reading for pleasure."
