Introduction: Why Peak Grading Matters

Whether you’re taking your first steps into mountaineering or planning your next big Himalayan expedition, knowing what you’re getting into is crucial. One of the most trusted ways climbers assess difficulty is through the UIAA Peak Grading System, also known as the French grading system. In this guide, we’ll walk you through what the grades mean and how they apply to popular trekking peaks in Nepal.

How the Peak Grading System Works

Originally developed in France and later adopted by the International Climbing and Mountaineering Federation (UIAA), this system combines numbers and letters to describe the technical challenge of a climb.

Grades range from I to VII, with I being the easiest and VII the most extreme.
Each grade can be fine-tuned with subgrades (e.g., + or -) to reflect slight variations in difficulty.
It’s used globally to give climbers a clear idea of what to expect — whether it’s a gentle ascent or a tough technical challenge.

Grades Explained: From Easy to Elite

Let’s break down each level of the grading system in simple terms:

Grade I / F – Facile (Easy)

Think of this as a scenic mountain hike. These routes involve walking or light scrambling, suitable for beginners with minimal climbing experience.

Grade II / PD – Peu Difficile (A Bit Difficult)

These routes require a bit more effort. You might encounter snowfields or gentle rock faces. Basic gear and knowledge of mountaineering techniques are helpful.

Grade III / AD – Assez Difficile (Fairly Hard)

Now you’re climbing. Expect steeper terrain, ice or snow slopes, and the need for intermediate climbing skills and rope work.

Grade IV / D – Difficile (Difficult)

Climbs at this level demand strong skills, endurance, and experience. Technical rock and ice sections are common.

Grade V / TD – Très Difficile (Very Difficult)

These are serious climbs that push your physical and mental limits. They require advanced climbing techniques, glacier travel, and high-altitude experience.

Grade VI / ED – Extrêmement Difficile (Extremely Difficult)

Expect long, complex climbs with high exposure to risk. Only seasoned mountaineers with exceptional skill should attempt these routes.

Grade VII / EX – Exceptionnellement Difficile (Exceptionally Difficult)

The pinnacle of mountaineering difficulty. These routes are reserved for elite climbers and involve extreme weather, technical terrain, and life-threatening risks.
