Europa-Park, Rust, Germany
Europa-Park features a rollercoaster called the Megacoaster (good name) that takes you from O to 100 in 2.5 seconds—hint: that is FAST. You can also hop on board a raft experience a water rafting adventure without ever leaving the park, and yes, there are kid-friendly activities as well.

Tivoli Gardens, Copenhagen, Denmark
In Copenhagen, Tivoli Gardens is a must-see; it’s got everything from old-school rides like bumper cars and Ferris wheels to thrilling drops and free falls, and with Vertigo, the park’s wildest ride, you experience 5G, “which means acceleration at five times the weight of gravity.” In other words, you go really fast. If rides aren’t your thing, explore the beautiful gardens or enjoy the various shows and musical performances on the park grounds.
