Príncipe Real is known for its gardens and cafes, and offers plenty to see and do without spending a fortune. You can budget for the top local attractions that interest you most, such as Rossio Square, and then look for sights and activities that cost little or nothing at all. If you're looking to enjoy the area's natural beauty, you can get outdoors at Torel Garden, Eduardo VII Park or Miradouro de Santa Luzia.
