The northern and eastern part of the hill merges into a common, maintained through grazing, with primrose blossom in spring.

[2] At the foot of the hill lies an elevated beach plain resulting from land uplift due to release of pressure when the heavy ice sheet covering large parts of Denmark melted away 10.000 years ago at the end of the last ice-age.

The coast down from Jernhatten is known among anglers and divers, due to a varied sea bed with kelp and stones, giving favorable conditions for fish life.

[2] On this stretch there is also a hill with angled beech trees, growing on unstable ball clay, that is slipping into the sea.

The tidal difference in the area is normally negligible in the order of one foot, so one does not have to worry about being cut of, even though the beach down from Rugaard Forest is narrow to pass at some places.
