Must visit butterfly beach, palolem beach ,arambol, spice plantation , dhudsagar falls and water activities.
stay options mykonos blu (north goa) , the nilaya hermitage ( really classy north goa but costly - murder 2 was shot here), the latlit golf spa resort (south goa)
South goa - peaceful and clean beaches are there. Less crowd. Beautiful churches
North goa - more commercialized, anjuna baga and Callenguate beaches, water activities like parasailing banana boat ride, water scooter. Disks and pubs (titos)
