I recently spent a week in the Mentawai Islands in Indonesia, where I work as Director of Programs. The Mentawais are a group of islands in the Indian Ocean and accessible from Sumatra only once a week by overnight boat. It's about as close to the end of the Earth as most people care to get.
Mercy Corps has been active in this far flung location since October 2010. Rather than write about my experience here, I tapped into my love of photography and video to put together this video blog of my time there: http://www.mercycorps.org/countries/indonesia/24978
