If you use a dipole or other horizontally polarized antenna near the 
edge
of cliff you will have a very low take off angles (comparable to a 
vertical over salt
water)  so it is possible to work some pretty good DX.  Also having a 
clear,
unobstructed view of the horizon helps a lot.  Vertical monopoles with 
ground
mounted radials often don't work that great in these sorts of 
environments due
to the poor soil conductivity resulting from the rocky terrain.
