Saint Louis Zoo
With the opening of Sea Lion Sound on June 30, it's sure to be a popular weekend at the Saint Louis Zoo. Zoo officials recommend visiting during the cooler times of the day (the zoo is open from 8 a.m. to 7 p.m.), and take advantage of misting stations, water fountains and the water play area of Emerson Children's Zoo. Several buildings are air-conditioned, including Penguin and Puffin Coast — where it's downright chilly at 45 degrees — Monsanto Insectarium, Primate House, Herpetarium, Bird House, Lakeside Cafe and many other buildings. The new sea lion viewing tunnel is also air-conditioned.
Six Flags St. Louis
If a trip to Hook's Lagoon at Hurricane Harbor doesn't cool you off, stop by any of the restaurants at Six Flags for free water, or hang out in front of one of the park's numerous misting stations. For some air conditioning, visit either of the theaters for some cool entertainment. The Palace Theater Lobby acts as a cooling station for guests that need a break from the heat.
Museum of Transportation
It's always cool in the Creation Station, and the Museum of Transportation has added additional boarding times at the heat of the day during the holiday week. A 1 p.m. session is open June 29 and July 2-6 (regular boarding times are also available at 9:15 a.m., 10:30 a.m., and 11:45 a.m.). Better yet, ice cream treats will be served at the end of each session during the week of Fourth of July.
Missouri Botanical Garden
The Missouri Botanical Garden encourages its guests to BYOB — bring their own water bottles. Special water fountains are available throughout the garden for refilling bottles. Guests will find plenty of shade under the trees, and kids can cool off in the splash area of the Doris I. Schnuck Children's Garden.
The Grafton, Ill., water park is encouraging guests to remain hydrated by adding water stations during the heat wave. Raging Rivers has also added an additional emergency medical professional to their schedule to help out with any heat-related health conditions. To protect their feet from hot surfaces, the park is encouraging guests to wear sandals or other footwear while walking through the park.
Free ice water is always available at The Muny. However, guests are also encouraged to dress for the temperature and bring ice-cold beverages. Small, soft-sided coolers (no glass or metal) are allowed in the outdoor theater.
