Houston earns all of Texas’ superlatives: biggest, hottest, and—thanks to the NASA Space Center—most out of this world. A guided tour of the city offers insider insight into the city’s wacky and wonderful attractions, from the old-school amusement park rides at Kemah Boardwalk to the USS Texas and San Jacinto Monument commemorating the Texas Revolution with a 220-ton (200-metric ton) star. Spend some time browsing the 60,000 works on display at the Museum of Fine Arts; travel underground on a tour of the city’s vast tunnel system; or eat and drink your way through the day on pub, brewery, and food tours that showcase the city’s historic, haunted, and straight-up honky-tonk charms. Those who prefer fashion to food can explore funky thrift stores and high-end boutiques on a shopping tour, while those looking to beat the heat can fill an afternoon of family fun at the Downtown Aquarium or the Houston Museum of Natural Science. For a fully customized itinerary, choose a private tour; or save money on a group sightseeing tour, including options to roll in style on Segways or hop-on hop-off buses. Finally, be sure to check out nearby haunts such as historic Galveston Island, known for its Victorian mansions and white-sand beaches.
