The sand is perfect for it. Bring some pails and shovels for them. If you don't have that stuff there are shops all around that sell it.
Yes sandcastle can be made, but it is normally windy. So make them strong!😊
Go out to Mustang/Padre to make real sandcastles with real sand. North Beach, renamed Corous Christi Beach to fool tourists, is a nice place to look at the water. It's just off the ship channel and so close to refineries that you don't want to get into the water here. Guides earn money by lying; listen to locals.
Bring a bucket and get some beach water, and it to the sand to make it stick together a little better. It's okay as it is, but that may help keep it strong. Have fun!
