Statue of Liberty, New York, NY

Lady Liberty’s crown, which reopened after an eight-year hiatus in 2009, is scheduled to close again in November (along with the rest of the statue) for at least a year’s worth of safety upgrades, so act fast to see the famous 125-year-old French gift from the inside. As you exit the ferry at Liberty Island, you’ll need to purchase a Crown Visit wristband at the information center. The only thing you’re allowed to take inside is a camera. Even cell phones and wallets are no-gos, so travel light and bring two singles to feed the three-hour lockers where you’ll stash your goods. (There’s no change machine, and to complicate the matter further, only singles and dollar coins are accepted). One wardrobe must: shoes with good grip. Descending the crown’s 354 steps can be a slippery affair.
