The gorge of Messonas is the continuation of the gorge of Havgas to the south-east, in the direction of mount Thripti. It requires special equipment and skill.
It is also good for trekking, on the ancient path which begins at Kavoussi, continues via Havgas and then carries on parallel to the gorge of Messonas.
It is 2 kilometres long in total and the elevation difference between the entrance and the outlet is 450 metres.
