The welcoming destination of Greenwich is a good choice if you've been considering a getaway with your children. The museums, sightseeing tours and cafes are just some of the things that make this an attractive spot for a family holiday. Fly into London (LCY-London City), which is the closest airport, or Heathrow Airport (LHR), which is located 21.5 mi (34.5 km) from the centre of Greenwich.
