With rides named Mind Eraser and Brain Drain, it's clear that Elitch Gardens is a thrill-seeker's paradise and, not surprising, a perennial teen favorite. But there's a little something for everyone at this park that first opened in 1890. Twister II, the popular 10-story wooden coaster, perfectly evokes the park's old-school/new-thrill vibe. A portion of the grounds are also devoted to a summer water park, which features about a dozen attractions including high-speed slides and drops, lagoons and wave pools. Parking on the grounds is pricey; consider visiting via the RTD bus or Light Rail, which stop just outside the park. Do note that height requirements are enforced on rides, so check the park's website before going.
