1. Dorney Park


While summer is in full swing, the price of admission to this Pennsylvania amusement park (about a two-hour drive from Manhattan) also includes full access to the Wildwater Kingdom water park. The 28 water slides offer the same heart-racing thrills that the best roller coasters do, with the added bonus of a climactic splash at the end. If you're looking for that kind of excitement, you should try the 450-foot-long freefall body slide Python Plummet, race your friends on the Aquaracer, or hold on tight to your tube on high-speed twisty slides like the Constrictor or Boa Blaster. For a less intense chlorine-filled experience, try floating on the Runaway River or Wildwater River rides, which drift tubes through features including mists, fogs, fountains and "hydra-swirl" whirlpools. 3830 Dorney Park Rd, Allentown, PA (610-395-3724, dorneypark.com). May 1–Nov 1; hours vary. Adults and children taller than 48 inches $39.99–$44, children 3 and up under 48" $34, ages 2 and under free.
