This is a seed I found which spawns you on a small grass and sand island surrounded by water. There are a few ravines directly below the island which cross over including a very large Abandoned Mineshaft. There is also a very large spherical cave once again directly below the island. The whole underground is densely populated with a large number of cave systems.

This seed is perfect for Survival Videos or Lets Play for servers which want to focus on survival rather than building.
