Reeking Cave

It is located to the Northwest and underneath the Thalmor Embassy, to which it is connected by a trapdoor.

Description
Reeking Cave is a small unmarked cave inhabited by a Frost Troll.

To find it from the outside, fast travel to the Thalmor Embassy. You will land in front of the gates facing North. Turn West and head to the rocks nearby. Carefully descend those rocks, then continue downhill until you reach the road. Turn right and follow the road downhill (there will be a line of rocks on your right), the entrance in nearby. Look for a narrowing with a rock on the left and a large tree on the right. There will be another tree on the right about ten feet further downhill. Between the rock and tree is a dark arch, which is the cave entrance.
