Vagator is one of the best beaches of Goa. As soon as you reach, you will see a local market abundant with all kinds of beach wear. Decend a few steps and the majestic view of the clear sea with a lush green hill complimenting it will certainly blow your mind.
Would recommend walking to the farthest end of the beach as it is not as crowded and you can enjoy the serene view.
Rent a shack and bask in the glory of the sun while sipping on a bottle of beer or a glass of wine.
As the water is clean, as compared to other beaches, I will recommend taking a dip too.
If you are not on a budget, do try Thalassa, a famous restaurant located on the hill top. The restaurant is known for its food and the breathtaking view from the hilltop( try visiting this one at the time of sunset) .
Overall, this beach is a total hit.
