The Floe
The Floe is a location in Conan Exiles and one of the entrances to the volcano with a loading screen.
It can be found above the right statue of Ymir in front of The Temple of Frost. It is a small cave entrance that leads you straight into the volcano.
If you turn left at the start you will come to The Shattered Stairs after a jump passage and if you orientate yourself to the right at the start you will reach The Pens.
Unfortunately due to the loading screen, this route may not be used to extract thralls out of the volcano as the thralls disappear when entering the cave.
