Start your day by exploring the popular beaches in North Goa such as Baga Beach, Anjuna Beach and Vagator Beach. Spend time sunbathing, playing beach volleyball and swimming in the Arabian Sea. In the evening, head to Tito's Club in Baga for a night of dancing and partying.
Take a break from the beaches and get your adrenaline pumping with some thrilling water sports at Calangute Beach. Parasailing, banana boat ride and jet ski ride are some of the popular water sports activities. In the evening, hit up SinQ Nightclub in Candolim for a wild night of partying and cocktails.
Take a long drive to South Goa and spend some time on the secluded beaches such as Palolem Beach and Agonda Beach. You can as well have a quiet day shopping at the local markets near the beaches. In the evening, go for a lavish river cruise and party on the Santa Monica Resto Cruiser and let it be the perfect ending to your 3-day bachelor party in Goa.
For more time, add a day trip to Dudhsagar Waterfalls. For less time, skip shopping at local markets and spend more time clubbing and partying. Note that some clubs may have dress codes, and it's wise to check this beforehand. Finally, use sunscreen as much as you can during your beach time.
