I find myself writing in similar settings a lot. A lot of my stories take place in remote places largely untouched by civilization. I'm not sure why I do this, that's just the way it comes out when I'm formulating a story. Perhaps it's because I don't like dealing with time period, so the further away from cities and technology I am, the less I have to explain what year it is.
Islands
Jungles
Cross Country stuff, like Lord of the Rings
Abandoned places, like temples and warehouses and old ruins
All these places are places where people can't really dispute what you write. I think that's why I put my characters there. I can do whatever I want without having to do too much research about facts. I just want to tell a story, not dwell on the nitpicky details of a setting.
My favorite settings to read...
TDF, of course
The Dark Tower universe, Stephen King...the ultimate Anything Can Happen setting
Jurassic Park, Sphere, Timeline, Prey, The Andromeda Strain...pretty much anything by Crichton has a cool setting.
