The gorge itself is a fascinating relic from the time when 16 active water mills stood here in the 19th century! 🏞️✨ They supplied the region with flour and still shape the name of the gorge today ("Mili" means mill). Today, you can discover many dilapidated mill ruins along the riverbed – with information boards that tell you the history.

The Apoplystra folds are located near Agios Pavlos in the Rethymno region and are a series of impressive rock formations distinguished by their vibrant colors and intricate patterns. These folds are the result of intense geological forces that, over millions of years, have compressed and twisted layers of sedimentary rock, creating a visually captivating landscape.

Around 50 million years ago, the region was subjected to intense pressure from tectonic movements, causing the sedimentary rock layers to fold and deform. This process led to the unique, angular formations that can be seen today and are to be designated as natural monuments of Greece due to their geological significance.

A highly recommended hike. There's plenty of parking (extra touristy 🫣😅). Restrooms are also available, and they were quite clean. The signage is a bit outdated, but if you have a cell phone or something else with you, you'll find your way easily. The route is quite challenging; the first 1.5km involve a good 200 meters of elevation gain. The view, however, is simply stunning. Anyone who wants to see wildlife will definitely get their money's worth here. We saw several mountain goats, vultures including their nests, and various other small animals. The highlight is the chapel, which unfortunately was somewhat damaged when we visited. We definitely recommend this route and consider it a must-do for anyone in the area or on Crete.
