Here is a winding cliff of 2400x2400 meters, where small caves and inlets are hidden.
Interesting basic environment, with which you can prepare your own original scenes.
Notes: The scene include 1 simple terrain, modeled in Acropora and texurized and populated in Blender (Render Cycles).
The terrain was populated with 2 eco-systems (by ParticleSystems).
