If Goa is too busy or crowded for you, there are other destinations that would give you almost the same kind of vibe. Some of these places are located in our neighbouring countries, while one can be found in Malaysia.
Quieter than Koh Samui and definitely less crowded than Phuket, Koh Phangan is where one goes to completely unwind. Unless, of course, you visit during the full moon party seasons. The beach parties here are epic, but at the same time, you would still be able to enjoy some quiet time during the day. The locals here are more laid back too, and you don’t get disturbed by friendly beach vendors as much.
