Minecraft wiki entry for Multiplayer_PvP_bases, associated text: Selecting a spot for this is hard. As previously stated, don't make this thing in an extreme hills or jungle biome. If it's high enough over an ocean, plains, desert, etc.... then it will take a while to notice and often be obscured by clouds. If it's over an extreme hills or jungle, anyone getting materials from a tree or climbing a mountain will look up and see your precious base sitting there. You don't want that. Instead, build it over a valley or a plain or desert. That should help disguise your place. Another idea is to build it over a plains forest, because most players will travel beneath the trees and will not notice the great big shadow on them. Don't build it over forests, though, if the trees are too tall or if they're too sparse, as players could notice the shadow or be high enough to see your base, and don't build it if the trees are too dense because most advanced players will travel above them to avoid monsters and hiding players, and it's a lot easier to walk on, and ultimately see your base.
