The journey to the tomb is actually fairly boring. You stay on the road for the most part, but veer off through the forest to the East after about two hour's journey. When you reach the mountains, it takes some time to find the entrance, but thanks to the maps and journal, you find it hidden behind some vines and overgrowth.
