Ok, then you are deploying!
The fortress is amidst a maze of narrow canyons and valleys. However, the building itself protrays high out of these rock formations. From a nearby bluff- about a ten minute walk away- you can see it all. It is of very traditional build; in fact, there is even a hi-tech drawbridge and gatehouse, the only access to the fortress itself being across that bridge, a 'moat' of thin air being all that otherwise surrounds the fortress, built on an isolated outcropping.
There is a main route up, or you can pick your way across the canyon tops- that will take longer though.
