Bring your own lunch & towels . Definitely wear walking shoes (!) not flip flops to enjoy the long walk around the island. Totally worth the day trip as the water was turquoise, pristine & warm. To get the tickets walk all the way to the end of the waters edge. There you will find the ticket office to swap your QR code for a piece of paper ticket ( which is a must)

the island is beautiful, we visited with our 4-years old son in late January and also spent nice time there. Except for the Royal forth, you can walk around in the nice nature, around and in the island. You can spend there 1 hour or 4. Just take some food and drink with you if you go off-season, there are no restaurants or shops open. The only disappointment was, that we bought tickets via GetYourGuide for our son as well, because there was written "children 4-12". However, later I found original web-pages of the ferry company, where you can buy tickets slightly cheaper and olso "children 5-12". So 4-years old are free :-(

Good organisation to ferries; remember to exchange voucher for tickets at the office. Lovely crossing; beautiful views. Fort fantastic; well worth a visit. Beaches/coves really not that appealing for a swim due to the dried seaweed on the beach which resembles feathers!!!! Yuk... best avoided; go for a walk & then head to Cannes beaches!
