There are a number of ways to approach this area. Most will recommend that you come up from Benkongerike, to the Southeast, you will be able to climb the rocks that overlook the area. This is especially helpful for Archers and Mages. It will trigger the Dragon and the Draugr below who will start fighting.
Otherwise, you will be approaching from the Northwest. This area is still very defensible because of the high amount of cover. You can always get into the huts which dot the slope up. This will provide protection from the Dragon and the Draugr Deathlords which populate the area.
