Cross the famous Samaria gorge.Take the early morning bus going to Chania. On the way (near Rodovani), the driver will let you off to catch the bus coming from Paleohora and going to Omalos. Cross the Samaria gorge and after 6-7 hours you will reach the coastal Agia Rourneli, from where you take the boat back to Sougia.
Take the boat to Agia Roumeli and walk the «lazy way» in the Samaria gorge, which goes up from the mouth of the river up to the Iron doors (Sideroportes), the narrowest point of the gorge. You will return to Sougia in the afternoon in the same boat.
