Everyone is different, with different beliefs. I don't believe there is anything after we die- nothing, so I don't see my spirit as wandering in some dark place. I have hiked all over the world, so while I love nature I don't want my body lying somewhere alone in the dirt eaten by animals and then maybe discovered by some unsuspecting backcountry hiker who may stumble upon it and be traumatized by the state it might be in by then. I also don't want to create work for the Rangers, since depending on where they find you, it can take days/ hours to bring the body back. I have seen rescues in Colorado Rockies where many tourists would do stupid things and the Rangers had to rescue them at cost of $10,000 plus. I just don't want to be a bother to strangers. I want to go quietly, with least trouble. I don't care if society didn't treat me well, I am not going to stoop to their level and cause trouble to others who did me no wrong.
I'm going to do it in a hotel, and while I feel guilty about that as well, I am going to leave some extra money for them for their inconvenience. I prefer to be cremated, clean end to all my cells and destruction of DNA forever. The only other place I wouldn't mind is burial at deep sea, but it is impossible to achieve without help from someone who can drive a boat and dump body. Where is Dexter when you need him, eh?
I had my fill of nature in one last trip to several spectacular National Parks this Aug-Nov. i can just watch my videos before I die. I love all National Parks in USA. I don't feel like you do to be away from USA. I think America is beautiful. I separate the natural beauty of this land from the people I encountered or politics. I have no family or friends who care about me. Even so, I feel people have nothing to do with how beautiful the land is. Nature is one true thing and the beauty of American land, it's mountains is unquestionable. Without divulging my location, I can say I live in a beautiful state so I can still see beautiful things from my window. I am a big fan of America "the beautiful", in terms of its natural beauty. I always tell Americans to support its National Parks and visit all of them vs going overseas, if they don't have a lot of money.
The Himalaya are jaw dropping beautiful, but I wouldn't want to die in Nepal, Tibet or India. Yuk. No way. The Swiss Alps are beautiful but frankly I found the Swiss (mind you only what I experienced, not a generalization) not very friendly people. I did not enjoy it as much, people wise. The country I absolutely love is New Zealand- it is beautiful, with Kiwis being the nicest people in the entire world. I wouldn't mind dying there. I considered Bay of Islands, Milford or Mt.Cook. But frankly, the Colorado 14,000 ft mountains, or GNP of Montana, are way more beautiful than the Southern Alps of NZ. I can name 100's of beautiful spots I have hiked, in the RMNP, that tourists don't go to. I just don't see the need to find spectacular beauty anywhere else when it is right here at my doorstep in the USA. It is memorable - purple mountain majesties and from sea to shining sea- Denali, Yosemite, GNP, RMNP, Hawaii, Grand Canyon, New Hampshire White Mtns, Blue Ridge Mountains....take your pick. Any direction you pick in the USA- N, S, E, W, you will find a gorgeous National Park. So I guess I respectfully have to disagree with you.
But I do hope you find your perfect spot. However, if as you said it is all in your mind/ psyche then, if you are not at peace with it, there is no spot on this Earth that will be good enough. Good luck and peaceful journey to you.
