I probably won’t be 100% helpful but wanted to write. Our family has been to both. Greg dove Balmorhea and the kids and I snorkeled and swam. It was beautiful but definitely a nice little drive to get there. Our family has been on the glass bottom boat tour at Aquarena Springs and it looked like it would be a neat dive. I’m sure you’ll get more responses but I wanted to add my few cents worth. ;O)
