I noticed the last time I went to Hawaii, there was a ton of hostility toward us outsiders by the locals. It was very noticeable. I was on Maui, and some local chewed us out for just hiking on a regular trail that our guidebook recommended.
There were also signs in a bunch of places in Hana, which basically told tourists to keep out to “respect” the property. These signs too were near regular beaches and trails.
I get it if tourists are trashing stuff. But tourism is the lifeblood of that place, and that attitude towards people just doing normal things was really nuts.
