This little Pillbox is located in the corner of the small beach behind the Bus depot in Shek O. If you have not been there before there is a little Bar called "The Back Beach Bar" which is a fantastic place to "Re-hydrate" after a walk or a day on the beach. It very reasonably priced with beers $20/Bottle, right next to the beach, with a great view. Perfect before/after having a Thai meal.
I went for a little walk a couple of weeks ago from Tai Tam to Shek O. Along the way I took a couple of photos of the Pillbox right on the waters edge opposite Red Hill.
