Houston is the largest city in Texas, on the Gulf Coast, and is served by two commercial airports: the large international hub at Bush Intercontinental and the smaller Hobby Airport closer to downtown. Summers are hot and humid and winters are mild, so spring and autumn are the most comfortable seasons for visiting. Most visitors will want a rental car or rideshare, though METRO buses and light rail cover the central areas.
