White water rafting is one of the classic, wild activities in the outdoors. It is also an opportunity for an unbelievable family adventure. Around the country, there are several rivers—and rafting outfitters—that are perfectly suited to the entire family.

Here are three of the best:

New River Gorge, West Virginia

Rafting in West Virginia is renowned for its established infrastructure, reliability and easy access. These things make it an obvious choice for a family vacation. Famous areas, including the New River Gorge, offer everything from lazy floats to intense Class IV runs.

Grand Canyon, Arizona

For really bold families, a multi-day trip down the Colorado River in the Grand Canyon is the penultimate adventure. Guided trips typically pack in boats-worth of supplies so the overnight adventures are far from “roughing it.” Instead, evenings are catered in a rugged luxury style, allowing everyone to rest up for the next day’s activities.
