Texans flock to sandy barrier isles like Galveston Island to frolic in the warm waters of the Gulf. You could do the same, or make a visit to the stately homes that grace the island. Or go on a mission to mainland Houston, to tour the impressive NASA Space Center.

Nearby stand the great pyramids and temples of their ancestors.
