South Outpost Island

The South Outpost Island is in Exbel and can be accessed after beating Mineral Cavern. It has a Kangaskhan statue and Chimecho Assembly. There is also a rest stop for 3,500 Poké. The entrance to Southern Sea is here and the path to Archford Cove, which has the dungeon Crescent Islet and is how players must gain initial access to Archford.

If Southern Sea has been beaten, you can come straight to here using Surf on the dock near the entrance to Mineral Cavern.
