There is a long covered passageway that has been cleared of the sifting sands and rising water — it was built by Seti I and contains the inscriptions of the Book of What Is In the Duat and the Book of the Gates. This was probably finished by Seti I’s grandson. It has a sharp turn when it enters the Osirieon, but it is closed to tourists. Mark and Bessem walked over the roof to the end and tried the locked gates. While they couldn’t get inside (and I was pretty sure they’d plummeted to their death somewhere!), they did get some pictures of the well-restored causeway.
