Although Estonia is the smallest of three Baltic states, here are numerous interesting geological monuments. In most areas of Estonia you could find the bedrock outcrops - in southern part beautiful Devonic sandstone cliffs in the western islands - Siluric limestone cliffs but in the northern part - impressive chain of Cembrian and Ordovician cliffs - the famous glint. For Estonia there are characteristic such nature wonders as unbelievably huge boulders, meteoritic craters, peculiar carst phenomenons... just name the Wonder Well - it may look like general countryside well, just sometimes over the well-curb is falling spring water in great amounts!
The waterfalls mentioned in this description and known to the author are located in the northern part of the country. Still it is possible that there are small, temporary waterfalls in southern part of Estonia and in islands.
