Traveling from the Seattle-Tacoma (SEA) airport to Houston Bush Intercontinental (IAH) gives you a taste of two vastly different cities. Houston has many exciting things to see and do for those on vacation or business, and a rental car puts everything within easy reach. Head over to Lake Houston after your arrival to enjoy some time outdoors, where you’ll also be able to take advantage of the warm weather.
Houston is full of exciting museums and attractions to explore, including the Armand Bayou Nature Center, an example of one of the city's many green spaces. Visit the Museum of Cultural Arts Houston for interesting cultural exhibits, or the Battleship Texas in nearby La Porte to see the famous battleship that endured two wars. If you're willing to take a drive south of the airport, Space Center Houston, the Kemah Boardwalk, and the city of Galveston are within an hour's drive.
Your flight from Seattle to Texas will take about four and a half hours in total. Because Houston is spread out with traffic on I-45 and I-10, give yourself plenty of time to get to and from attractions so that you don't miss anything. If you choose to use Beltway 8, also known as the Sam Houston Tollway, you will save a lot of time.
