North, Central, and South Texas are excellent hog hunting ground.....the west probably is too. Texas is a large state. Contact Texas Parks and Wildlife to see if you need any sort of permit since you are out of state.
My family has property in the Texas Hill Country (west of San Antonio-Kerrville area). South Texas has some very large hogs; the biggest I ever got. North Texas where I live has really had a big jump in the hog population. There is a place here, Hagerman Wildlife refuge, where the population has skyrocketed.
My lake house is nearby there and my neighbor there has property and the hogs have been playing hell in his pasture where he has always grown hay to feed his cows. In fact, he has hired some trappers with that new style hog pen which traps them.
For your first Texas hog hunt, I would do South Texas. You'll sure to get a trophy down there. Use a guide the first time until you meet folks down here. Everyone is friendly for the most part. We welcome hog hunters, have NO MAG capacity limits, and are a gun loving state. We need all the help we can get.
The dam hogs even tried to dig up my dead dog a few years ago. No joke. We were having a hot, dry spell, and the dam critters tried to dig him up. I thought it was coyotes, but, come to find out, coyotes would not have done that. It was the hogs. I also found tracks.
South Texas, the dam thing really get big, with big tusks. Get a guide and when your here, befriend land owners. They'll let you hunt the critters, I'm sure.
