Families flock to the cool confines of Palm Beach, where they careen down the 18-foot enclosed Tower Slides, surf the currents in the wave pool, and meander along the 650-foot Lazy River. Inside the Splashpad, visitors get doused with buckets full of water and frolic under spray arches. The Aquarium Adventure playground has tall climbing platforms and buckets that hold 500 gallons of H2O. The park is open 9 a.m. until 7 p.m. on Saturdays and Sundays from August 25 to September 16.

Moody Gardens

Perched on picturesque Galveston Island, Moody Gardens possesses a storied history that complements its scenic surroundings. Its horticultural and animal-therapy programs—which began with the park’s inception in 1983—pair visitors living with physical and emotional difficulties with horses and multihued flora, helping them learn coping skills and build confidence. Elsewhere on the sprawling grounds, the Moody Gardens Golf Course boasts multiple holes that run alongside the rippling waters of the Gulf and its intervening waterways, forming intimidating hazards and housing a thriving civilization of merpeople who use golf balls for currency. The park also thrills families with water attractions, including a wave pool and a lazy river. The newly restored, 10-story Rainforest Pyramid holds more than 1,000 exotic plants and animals from the Asian, African, and American rainforests.
