Ai-Petri (eastern peak) via south-eastern ridge, category 3B

The approaches to the route start from the Yalta-Sevastopol highway at the turnoff to Miskhor. The route begins along the ridge that goes left from the center of the eastern wall (moderate rocks, 40 m). The landmark is an inclined terrace located to the right of the ridge.

From the ridge, transition to a series of vertical cliffs with a weakly expressed counterfort, the length of this section is 20 m. Then:

• traverse left,
• ascend 30 m along moderate rocks,
• follow an inclined ledge to a vertical chimney.

The chimney leads to a ledge, from which difficult climbing up an inclined ledge leads to a rocky ridge where a yew tree grows. Continue towards a pine tree (difficult rocks, 15–20 m).

From the pine tree, move upwards and to the right along the rocky ridge. The path along the ridge is easy. The length of this section is 80 m. Then, very difficult climbing up overhanging rocks leads to the pre-summit tower. The length of this section is 20 m.

On the plateau, ascend along the ledges and join the trail leading to Miskhor.

The route length is 580 m:

• difficult rocks — 95 m,
• moderate rocks — 300 m,
• easy rocks — 180 m.

The ascent takes 6 hours.
