Can u get in the water that's in the first picture and second

I wouldn't recommend it... It's really hot, but it's open... You can touch it, but I don't think you're supposed to actually get into it. If you want to bathe in the springs, I recommend the Quapaw Baths. It's like Turkish baths, it costs $20 a person, and you can stay in all day. They have 4 different pools with different temperatures.

Yes if you want to get burned

Yes

Yes if you like hot water
