There is something for everyone in beautiful Houston, which is America’s fourth largest city! If you’ve never visited Houston you may not realize that it is home to a large community of cultural institutions, exhibits, performing arts, outdoor activities and more. In addition, the city has played an important and historical role as the main center of activity for NASA, giving Houston the official nickname of "Space City."

The best thing about spending time in Houston—in addition to its beautiful climate and friendly people—is the fact there is an abundance of activities to take part in which are inexpensive or free. Here are eight that might pique your interest:
