New York: Top of the Rock
Get there: 30 Rockefeller Plaza, midtown Manhattan
Head up the top of the rock for a mind-blowing view of the sprawling concrete jungle that is NYC. The lifts go up every 15 minutes and you can stay as long as you want, walking round for a 360-degree view of the unbelievable city. Best times to go would be for sunset and night for the lights. If you wanted to be super stingy, you could just go up the top of another extremely tall high-rise free of charge if you’re good at sneaking past doormen.
