In antiquity Jegindø comprised two neighbouring islands, divided by a shallow sound, Since then slow raising of the ground has transformed the sound to a stretch of low meadows or water meadows, that have attached the islands to each other.
Nonetheless at times – luckily only once every so many decades – a particularly high tide in the autumn will force salt water into Kringelkjær, Bjerregaard Dam and Lillefywer. Then, for a short while, Jegindø is once more divided in two.
The usual edge of meadows are totally lacking on the eastern part of the island. This is the stretch from Sandkrog to the point, there the steep cliffs alternate with green hills and brushy slopes inclining straight down to a narrow, stony beach. Here you can almost always find a sheltered nook, where it’s a pleasure to be even on the days, when a hard wind makes it a doubtful pleasure to stay on the windward side of the island. And you will find enough to look at if you have just the slightest interest in geology. Among other things the island offers a kind of clay that is so rare, that this is the only place in Denmark you will see it.
