On the slightly larger side, I was able to visit Easter Island at one point. Depletion of natural resources led to an all out class war that nearly wiped everyone out (see: the popular 'Collapse' (2005)). It is a very eerie place to visit because there is not much vegetation across large parts of the island and you can see the the extent of the island in all directions standing on one of the peaks. I couldn't really put my finger on it at the time but I definitely had an uneasy feeling being in such a remote location in the middle of the vast ocean. It hits you in the gut that you would be trapped on this tiny speck of land if it were not for the occasional airplane or cargo ship. I can only imagine what crew of the Bounty (or any other shipwreck) felt.
It's a similar isolating feeling on Pitcairn. There's no air access so I arrived via a two day boat trip from Mangareva. Once there my boat left leaving me with no way off for the time I was there until another arrived to pick me up. You become very aware of how problematic a medical emergency would be.
In the Netherlands we had a Dutch writer, Boudewijn Büch[0], who was obsessed with remote islands and as such visited many. He wrote his experiences in several books, which might be of interest to to some people.
I'm not sure if any of his books were translated to English though.
He also made a few documentaries for television, for example a visit to Tahiti[1] (again, in Dutch).
