Pretty much the title. I'm a big outdoors enthusiast, and love to get out and hike, camp, explore the backcountry, etc. I'd love to find some hot springs somewhere within "long weekend trip" distance of Houston. It seems like Arkansas is the best bet, but googling anything with "hot springs" in the title for Arkansas just gets you on the city and bathhouse rabbit hole.

Ideally, something that's a bit more natural, but if that's not possible any recommendations will do. Thanks in advance!
