Ha Gorge is located in eastern Crete, within the Lasithi regional unit, on the western slopes of the Thripti Mountains, north of Ierapetra and near the villages of Kato Chorio and Monastiraki.

It is considered one of the most impressive and wild gorges not only in Crete but in all of Europe.

The gorge begins at the Thripti plateau and descends toward the plain of Ierapetra, channeling water from the mountainous area to the lower regions. Its entrance is extremely narrow, about 3 meters wide, while the elevation ranges from approximately 370–800 meters at the upper sections to around 100–140 meters at its exit.

Ha Gorge is renowned for its unique geomorphology, which is the result of intense tectonic activity along the Ierapetra fault. Its walls are extremely close together, in some places only a few centimeters apart, creating a dramatic and almost otherworldly landscape.

Crossing the gorge is extremely difficult and dangerous, as it involves around 30–33 descents (rappels), with the highest reaching approximately 35 meters. For this reason, it is considered one of the most demanding technical canyons in Greece and can only be attempted by highly experienced canyoners with specialized equipment.

The name “Ha” is believed to derive from the Greek verb meaning “to gape” or “to open,” accurately describing the gorge’s deep and narrow formation.

The gorge remains a largely untouched natural habitat, with vegetation adapted to its harsh conditions and significant ecological interest. Its wild beauty and inaccessibility make it one of the most unique and striking natural formations in Crete.

Ha Gorge is not a typical hiking destination, but rather a place of exploration and adventure, intended mainly for experienced nature enthusiasts and canyoning experts.
