THE BEACH
I don't know what it is with the Indian peoples but they seem, as a collective whole, to be oblivious to the concept of carrying home their litter and waste. If you like walking amongst litter and filth, then I'd recommend baga. They've completely ruined what could be a veritable paradise with their attitude that the beach/street is a rubbish tip for their trash, and a public urinal to be used at their convenience. Beer bottles, plastic wrappers, used nappies, dog poop etc etc. You cannot walk freely without carefully navigating each step in front of you.
NIGHTLIFE
I can't comment on the nightlife because i was there only during the day.
BEING A WOMAN
If you're a young women, esp. of European ancestry and are starved of male attention, then baga is the perfect place for you. Men stare at you openly here, and that might make you uncomfortable.
WEED
Don't get caught with weed - the police are shamelessly corrupt and will extort you with as much as they think they can get from you AND keep the weed as well.
Those things aside, it's a great place.
