Trek Difficulty Level – Hiking Grades in the Mountains

The Trek difficulty level in the Mountains of Nepal mainly varies depending on the different geography, terrain, altitude, durations, weather, and the fitness level of the trekkers.

During trekking at a high altitude on the lap of the high mountains, one should be physically and mentally prepared to overcome all the consequences that might occur in the mountains.

Trekking in the mountains, some routes are easy while you might be facing challenging perspectives such as leaving behind the treeline zone and moving towards the alpine region. Where the oxygen level decreases and makes it difficult to breathe. We will move slowly as we are familiar with the high mountain environment (acclimatization) and get to the destination.

Some factor that affects the trek difficulty level in the high mountains is as follows:

Altitude Variations

During the trek in the mountains, the higher the elevation, the fresh and thin air you feel. As a result, it makes the trekkers on difficult to get full oxygen to breathe and it may also lead to Acute Mountain Sickness (AMS), whose consequences might be more serious if not treated properly.

Duration of Hikes

The longer the number of days it takes to trek in the mountains, the more trekkers should be physically fit and mentally prepared to tackle all the situations that might occur in the mountains.


The different terrain and the geography of Nepal make the trekkers more challenging to push to their final destinations. The Terrain is more rough and rocky which the trekkers need to pass via which might be more challenging.

Weather Conditions

The weather in the high mountains is unpredictable. It keeps on changing each minute. So, the trekkers need to be physically fit and have a strong mindset to overcome all the obstacles in the mountains.

However, trekking in high altitude can be more challenging and difficult to overcome the different obstacles in the mountain area. So, before trekking to the mountains consult with the registered trekking companies and hire a guide for a better smoother trekking journey in the mountains.
