When driving to STL by car, the most convenient routes to take are I-70 or I-170. A direct flight from St Louis to Houston should last two hours.


With the Museum of Fine Arts among its artistic hotspots, Houston is filled with admiration for Texas fine arts. This renowned museum includes the Bayou Bend Collection and Gardens and the neoclassical Watkin Building. After looking at European paintings and furniture, head to the Downtown Aquarium to see aquatic life in themed sections such as the Louisiana Swamp and Shipwreck.
