At the lower point of the river that passes through the Portela Gorge and a few meters before it meets the small plane of Keratokambos, the beautiful waterfall of Richtra is formed. Richtra, which is the pride of the inhabitants of Keratokambos, has a height of more than ten meters and has water during the rainy months of the year. When it has enough water it forms a double waterfall of unique beauty.
We can easily reach the point along the river from the exit to the beach. Above Richtra there are other higher waterfalls, but Richtra is the best known as it is easily accessed.
