Levels of difficulty for treks
No difficulty: example the visit of Kathamndu and its surroundings.
Treks usually in lodges with steps not exceeding 5 hours a day.
The altitude reached does not exceed 4500-4700 m and no night above 4000 m.
Treks in lodges or tents with steps of 4 to 7 hours per day and whose altitude can exceed 5000 m when passing a pass.

Trekking in complete autonomy or partly with stages of several days in altitude (above 4000 m) with low temperatures.
Passages of passes or walk on trays to more than 5000 m.
Example: CB of Kangchenjunga
Treks very demanding because of their autonomy, their duration, the length of some stages with passages over 5000 m and nights above 4500 m or 5000 m.
Treks requiring good endurance and a taste of effort.
Example: Rara Lakes trek
Levels of difficulty for treks peaks
Contrary to popular belief a trek peak is not "easy".
These are high mountain glacier routes. Good mountaineering skills and good physical condition are required.
You must be equipped with your mountain equipment and know how to use it. At the bottom of your trek peak page you have the list of mountain gear needed for your summit.
Besides, technical problems, do not neglect:
the day of the ascent you will already have many days of walking so accumulated fatigue,
from mid-November it can be very cold,
finally, these ascents take place at more than 6000 m.
