Hii scoopy ,it will be great to help you clearing your travel queries . some beaches get close by 1 a.m. while there are some beta which are open for whole night and especially famous for nightlife like Calangute beach. I want to stay whole night near beach that I will suggest you to rent a cottage as there are plenty of available if you are planning to stay on beach whole night boozing in with peers you can do this especially nightlife of Baga beach is pretty famous but I would like to warn you not to sleep in sand for whole night because you may find crabs roaming on and around you in early morning.
