Minecraft wiki entry for Nomadic_experience, associated text: This might be one of the most efficient, and safest, ways of making a one-night shelter. All you do is go up in a tree and barricade yourself with any material. This works especially well with larger trees (the ones with branches). Note that spiders may be able to get up the smaller trees. Also, a plus-side to this shelter is that you have a natural way to see outside.
