go to vagator/anjuna. baga is more middle aged touristy. go to the nine bar in vagator and ask around, since the government cracked down most of the parties start at like 1am in an out of the way place. nine bar has music until the early evening but then it shuts down, people go to cafes and hang out waiting to get confirmation on where the party that night is. also in anjuna there's another established place to dance called paradiso, which i think is a lot of fun, with a small dancefloor but still a very cool space with platforms outside to chill. both of these places are more commercial than the underground beach parties but they're still fun. and you can find out about the underground beach parties. there's also a day place in vagator that has day parties but i forget the name.
