I’ve been to Goa a few times, and for a family holiday, staying near beaches like Calangute or Baga is a good idea. These areas have lots of activities for kids and good facilities. We found a hotel with a pool, playground, and other amenities that kept our children entertained all day. If you're open to other options, you might also want to check out places like the
conference venues Blue Mountains. They also offer great family escapes with beautiful scenery.
