Be sure to have plenty of offense and plenty of healing! The group MUST stay together or you will get slaughtered. However, a well coordinated party will come out OK. The pair of rest shrines lies outside the gate to the right. There is a resurrection shrine only (no rest shrine) inside the gate. Some people like to use the small opening inside the gate to the right. It is said it leads to the spawning point for the kobolds. Good XP's for this quest.
