Thrypti (Greek: Θρυπτή) is a mountain range in Lasithi in eastern Crete, Greece.

The NE border of Ierapetra is so irregular that some small pockets of Thrypti might inadvertently be in neighboring Siteia municipality.

The Bebonas valley cannot serve as a border near the coast, as it only descends from its origin in the pre-existing mountains.

On top the massif are the montane slopes and plateaus of low enough inclination to support pastures, some agriculture or dendriculture, and villages.

The canyons, or gorges, are cut deeply into the edges of the massif by runoff from above, a process facilitated by the softness and solubility of limestone.

[3] The terrain offers a good starting point in Vainia, a settlement of Ierapetra to its NE.

The village is noted for Vainia Tower (35°01′33″N 25°46′49″E / 35.02574°N 25.78031°E / 35.02574; 25.78031), built by the Venetians 4.55 km (2.83 mi) from the city center at an elevation of 160 m (520 ft).

Through the bottom of the gorge is only a hiking trail, considered dangerous, but 20A bypasses it, climbing in hairpin turns across the upper slopes of Koufota, to arrive at Thrypti plateau at the 722 m (2,369 ft) contour line, where the original Thrypti village is located (35°05′28″N 25°51′48″E / 35.09119°N 25.86335°E / 35.09119; 25.86335) under the high point of the range, Afentis, which reaches to 1,476 m (4,843 ft) to the south.

The valley, called Havgas Gorge,[5] is caused by the Kavousi river, which drains westward from the slopes of Spathi, 1,177 m (3,862 ft) near Melisses, exits the massif at Kavousi, turns northward, and reaches Mirabello Bay at Tholos.
