This new walk (2020) has a lot of variety, including a bit of adventure. It starts in Asomatos, where you can visit the Papa Michalis Georgoulakis Museum (Oriseum). Then the walk takes you down into the Kourtaliotis Gorge to a small church and waterfalls before you walk down the alongside the river towards the Preveli Bridge and the ruins of Preveli Monastery (Kato).
Take into consideration there are steps down and up, you have to make a small jump and you have to cross the river twice, so your shoes will get wet.
You take the bus from Plakias to Asomatos and back to Plakias from Preveli Bridge. Or you can walk on using walk 8 to Preveli Beach, Lagoon and Palm Forest.
