A heritage tourism trip to Texas takes some special planning, depending of course on what set of parameters you choose to use in setting your priorities. Texas is so big, for one thing, that you need to have a specific plan in place before you start your trip to be sure you can get there in time to do anything useful. Even with the recently increased speed limits on some of the Interstate highways, if you are driving, it takes a long time to get from any one point in the state to another. If you are flying, seats tend to fill up early, so planning ahead is essential.
My recent webpage on Texas Heritage Tourism may be useful as you begin your travel plans to Texas. You will find useful links to the several regions of the state and suggestions of some historical, cultural and natural sites you may want to include in your visit. I travel through central Texas several times a year as we come from the Missouri Ozarks to visit our grandchildren and their parents now living in Austin (they earlier lived in Dallas).
While it is a long drive to West Texas, Big Bend National Park is a very special experience, if you are looking for something a little out of the ordinary. We visited at Christmas time, and it was a distinctive experience. Houston has the Johnson Space Flight Center, and Austin features the Texas Hill Country along with the Lyndon Johnson Presidential Library as well as the Lady Bird Johnson Wildflower Center (just a few blocks from our grandchildren). Each region features a different mix of experiences.
There are seven regions in Texas (each could be a state itself): Panhandle Plains, Prairies and Lakes, Piney Woods, Gulf Coast, South Texas Plains, Hill Country and Big Bend Country. Do you have relatives or ancestors in Texas? That will color your view of the state, of course, as well as have a direct affect on your choice of travel destination. I'd love to get feedback on your trip and your reactions to your visit!
