I biked through this afternoon for the first time. They don’t seem to have any security at the gates. I don’t know what hours the gates are open though; that is, I don’t know if they are open after dark. May wish to check their website first. During the day I don’t see how it would ever be an issue biking through.
Stick to the road though! The wide “bike path” next to the road is for the golf carts.
