How comparable is it?

Hikes / treks are always a good portion of my travels. Soon, I’m looking to do the Acatenango volcano trek in Guatemala.

Can someone who has done the Ala Kul pass trek in Kyrgyzstan give insight on how the two compare?

Either that one, or the trek up Fansipan peak in Vietnam.

At the time I did Fansipan (2017) I thought it was the hardest hike I’ve done, and the same with AlaKul in 2024.

Are either of them comparable to Acatanengo?

Trying to gauge difficulty.
