Do you have to camp here or is it like going to a beach where you can just visit for a day?

You can camp or day visit.

For a day or camping. So relaxing and Beautiful place!

You can camp here

My wife and I spent the day tubing down the Santa Fe, and then we floated in the springs for a couple hours. It was a bit less than $15 each (military discount) but even at full price it would have been a good value.

A day visit is $15 per person, and I believe that camping is $25 per person, per day. There are a lot of great spots next to the river and more farther from it, and pretty close to the springs.
