There are parts of the country where geothermal activity has created natural hot springs. I fantasize about going nude no matter how many people are there even if I'm the only one nude. I love finding grey areas where nudity is not expected or necessarily allowed but people might just tolerate it depending what mood they're in. These spots are popular with tourists so people might assume I'm German or Scandinavian and it's normal practice for me. I have to be careful because I've been in trouble with the law. When there's children about people tend to get uptight but in my experience kids are the least likely to get upset - they just roll with it. They don't know that it's unusual or have the indignation that adults have. If parents just say hey look at that guy - he forgot his swimwear and have a laugh and don't make a big deal the kids won't either.
There are natural hot springs all over the West. I have been to many in ID, WA, OR, and NM. Nudity is the norm any clothes free coed soaking is a great experience and usually free of obnoxious folks. Great experience and highly recommended.
My wife has been all over hot springs out west. I was never with her, but she said it was always nude, and large groups, too. She is incredibly shy, but she says it would be really weird to be the only one with a swim suit on.
I have always loved bareing it all at the beach or hot springs.We were at the hot springs the other night and about eight of us were nude when a couple families came walking in. We all were yelling that we didn’t have clothes on because they had kids .They say it’s ok and this girl about 12 or so jumps in and is trying to eyeball my shaved stuff .Very uncomfortable we had to leave
I go to a Japanese Onsen bath in the big smoke where nudity is normal. Closer by, there is a Day Spa that permits nudity as you're in your own little bath cubicle. There are hot springs dotted around this great country of Australia, but the very best are in the Top End (Mataranka Thermal Springs) and definitely no nudity allowed, even though I've fantasised about ducking under and ripping off the budgie smugglers, just " 'cause I can!".
