Cholpon-Ata is Issyk-Kul's main resort town — busiest in July and August when Bishkek residents come for the lake, quieter and arguably more pleasant the rest of the year.
The real draw for most visitors passing through is the open-air petroglyph field just outside town: thousands of stone carvings scattered across a boulder field, dating back as far as the Bronze Age, depicting hunting scenes, animals, and figures. There's no fixed route — you're free to wander the field and pick out carvings yourself, which some visitors find more rewarding than a structured museum tour.
Coming from Karakol, it's a full day round trip since it's the opposite shore of the lake — worth planning as a dedicated day rather than trying to combine it with something else.
