How are the rules with alcohol and is there anything to do in the winter besides swimming? Hiking or fishing? Im looking to camp in the next few weeks, 4 tents.

Alcohol is allowed please clean up after yourself and as long as you're not causing a ruckus late at night you're fine. If you camp farther away from the main springs it's like you have the whole place to yourself! Provided it's not a holiday weekend or summertime! They have rents there also.

As long as you don't do anything that would harm anyone, you are fine.

I think yoh can pretty much do what ever. Even swim at night till 12am.
