Ha gorge is located in the west slope of Thrypti mountain and exits near the village of Vassiliki, near Ierapetra in south Lasithi.
Its name derives from the verb “hasko” which means to open widely, to gape.
Ha is a rare geological phenomenon probably caused by tectonic asctivity.
It is considered one of the wildest gorges in Greece and very few experienced climbers have managed to cross it.
A similar attempt from a non experienced climber, without the right equipment and a guide could be prove fatal, as it has been in the past.

The gorge is quite narrow, particularly near its entrance, and in general its width doesn’t exceed three metres.
Its vertical stone walls rise at an altitude higher than 300m while its length is approximately 1km.
Before the entrance and in the interior of the gorge, there are quite a few small ponds and waterfalls, especially in the wintertime.
The highest waterfall in Crete of 215m height is poured in Ha.

The surroundng area of theThrypti massif as well as the interior of the gorge is a very important wildlife habitat as the small ponds form important wetlands for many migratory birds, and also endemic birds and mammals, insects and serpents.
