Six Flags Discovery Kingdom is located in Vallejo, California, less than an hour from San Francisco in one direction and Napa Valley in the other direction. The park runs the gamut of thrills, which include Cobra, Kong and Medusa, the latter of which is the longest and highest roller coaster in Northern California. A recent addition is “The Joker,” a 3,200-foot coaster featuring a zero-G barrel roll and reaching speeds of 53 miles per hour.

Youngsters enjoy train rides, splash zones and a roller coaster of their own (Road Runner Express), though one of the biggest highlights for families — and something unique to this park — is the chance to see and interact with animals. Families even have the opportunity to swim with dolphins!

If you’re planning to stay in town, consider a stay at the Fairfield Inn & Suites Napa American Canyon.
