The destination of Olivais is a good option if you've been considering a getaway with the children. The beaches and restaurants are just a couple of things that make this an attractive spot for a family holiday. Take to the air and fly into Lisbon (LIS-Humberto Delgado), which is the closest airport, or Cascais (CAT), which is located 13.1 mi (21 km) from the city centre.
