Make a splash at Jellystone Park™ Mark Twain Lake with a week packed full of soak-soaked excitement! Grab your swimsuits and your biggest water blasters because this is your chance to dive headfirst into nonstop fun. Whether you’re drenching your friends, racing down slip ’n’ slides, or teaming up for epic campground water battles, every day is a wave of adventure waiting to happen. Cool off with creative water games, laugh your way through our famous Wet Wagon Ride, and enjoy splash-tastic surprises with Yogi Bear™, Boo Boo™, and Cindy Bear™ cheering you on. Then on Saturday, dry off just long enough for an out-of-this-world Mad Science Show featuring jaw-dropping demonstrations and wildly interactive experiments that will wow campers of all ages. It’s the perfect mix of splash and spectacle for a week you’ll never forget!
