I checked some vacation options. There's Annapurna circuit for $1650, Manaslu circuit for $2000, Kala Patthar and Everest base camp trek for $2000 or $2500 if you add Ilsand Peak. There are also some more trekking peaks in Himalayas. And of course every one of these treks is advertised as the most beautiful.

So which one is the best option? And how difficult are those treks compared to European mountains? Are trekking 6 thousanders anything like Elbrus? Do Thorong La or Larkya La require significant experience in Alps or Caucasus?
