St. Louis travel tips
Do you know what a Climatron is? Visit the world's first air-conditioned greenhouse in St. Louis
The Missouri Botanical Gardens in St. Louis houses the climatron, the world's first greenhouse filled with conditioned air. It is covered with a geodesic dome enclosed in rigid plexiglass panels. Sophisticated climate control systems create rainforest conditions under the dome. More than 400 species of plants grow inside. The unusual look of the building and the full feeling of being in the rainforest have made this place very popular with tourists and locals alike.
Hotel prices in St. Louis may be affected by the Cardinals’ home games
Although hotel prices in St. Louis are roughly the same throughout the year (around $100 per night), they can go up slightly when the Cardinals play at home. To save money and avoid crowds of sports fans, it is better to plan your trip to St. Louis in the offseason or when the Cardinals are playing in other cities.
