If you have more time, try indulging in some water sports or yoga classes by the beach. You could also take a day trip to the lesser-known Divar Island for a quiet escape to nature.
If you have less time, consider skipping Dudhsagar falls and Anjuna beach to make time for some extra relaxation or a spa session at your hotel. Also, be mindful of the weather, as Goa can get very hot and humid in the summer months, so plan your itinerary accordingly.
