Hobøl is one of 10 municipalities which, due to their geographical placement miles away from the fjord / coast line, can be put into the area of Indre Østfold (Inner Østfold, the part of Østfold which do not have fjord or coast line), while those areas of Østfold who have fjord / coast line (Moss - Fredrikstad - Sarpsborg - Halden etc.) are called Ytre Østfold (Outer Østfold) and Nedre Glommaregionen (Lower Glomma Region).
