Crete is full of karst and geological formations, with caves being the most interesting, but also most fragile. This category hosts some places which have high geological interest and are worth getting known better.
Crete's Geology: How was it formed? 
Gray limestone atop mountain peaks and vertical cliffs, deep and narrow dark canyons, steep shores, shiny greenish schist, pale phyllite, light limestone eroded by rain and wind, fertile yellowish marlstone - it’s all here. No wonder Crete is a multicolour island.
Voulismeno Aloni 
Voulismeno Aloni is located approximately 15km west of Heraklion and next to the old road connecting Heraklion to Rethymnon, near the village Marathos. It is one of the weirdest geological phenomena in Greece. It is a very large sinking (karstic doline) with circular shape.
Komolithi is one of the most bizarre and interesting landscapes in Crete. They are met by the village Potamida (Kissamos province), at the valley of Tyflos River, about 35km west of Chania. These are alternating small hills consisting of soft clay, which due to time erosion, have turned them to wonderful conical shapes.
The folds of the rocks at position Apoplystra, between the village of St. Paul and the sandhills are remarkably colorful and have been proposed to be listed to the Natural Monuments of Greece.
From the village Astiraki, Malevizi province, we can reach the fertile plateau of Vaklia. Before meeting the plateau Strouboulas we meet the position Galia. Galia is a completely barren plateau in contrast to the fertile reddish soils of Vaklia.
This is an entire mountainside with spectacular naturally carved rocks having amazing shapes. They are extremely sharp and stand tall like meteors in the sky, and between them aisles are formed that leave space for walking and for a few shrubs and trees.
At Tripiti, you'll meet an imposing passage, an open cave, with 200m high cliffs and amazing views to Lagada and Mesada areas. According to tradition, once the Turks stole the legendary icon of Virgin Mary from Kera monastery, but the icon used to return miraculously every time. Once, the icon flew hill and crashed to the mount, forming this cave.
At the eastern end of the sandy beach of Plakias, at the base of the Karavos peninsula, the impressive limestone rock of Paligremnos is formed. Paligremnos is a geological fault with a great height and extremely smooth surface that exceeds 80 meters.
