If I remember correctly, you CANNOT bring one onto the island. There can be a lot of walking, but it is sort of what you make of it. We walked around quite a bit and went over to the fort. Even if you have small children (mine were 2.5 adn 4.5) they may be itching to get out of the stroller at that point. It is all shaded, which is nice. It is hilly and there is a footbridge which I think would be hard with a stroller, anyway. Good luck!
