Route Difficulty Levels

Understanding grading systems for hiking and mountaineering

Why Difficulty Grades Matter

Difficulty grades help you choose routes that match your experience and skills. Understanding these systems is essential for safe trip planning. Different regions and disciplines use different scales, so knowing how to interpret them can prevent dangerous situations in the mountains.

RePeaks Difficulty Levels

For trips and events, we use a simplified 4-level scale that's easy to understand:

Beginner

Suitable for first-timers. Well-marked trails, minimal elevation gain, no special equipment needed.

Intermediate

Some hiking experience required. Steeper terrain, longer distances, basic outdoor skills helpful.

Advanced

Significant experience required. Challenging terrain, may include scrambling, exposure, or glacier travel.

Expert

Extensive mountaineering experience required. Technical climbing, serious commitment, specialized equipment essential.

International Grading Systems

HikingSAC Hiking Scale (T1–T6)

Developed by the Swiss Alpine Club in 2002. Used throughout the Alps and increasingly worldwide for rating hiking and alpine hiking trails.

Grade	Name	Description
T1	Hiking	Well-marked path, easy terrain. Trainers OK.
T2	Mountain Hiking	Continuous path, some steep sections. Hiking boots needed.
T3	Demanding Mountain Hiking	Exposed sections may have ropes/chains. Alpine experience needed.
T4	Alpine Hiking	Sometimes unclear path, use of hands required. Blue-white markers.
T5	Demanding Alpine Hiking	Often unmarked, climbing sections (UIAA II). Ice axe/rope knowledge.
T6	Difficult Alpine Hiking	Very exposed, climbing up to UIAA III, glacier sections. Full alpine skills.

MountaineeringRussian Alpine Grades (1A–6B)

Used in CIS countries. Unique in considering altitude, route length, and overall commitment alongside technical difficulty. Grades range from 1A (basic alpine terrain) to 6B (extreme expeditions).

Grade	Description	Examples
1A–1B	Easy alpine terrain, basic rope work	Simple peak ascents
2A–2B	Multi-pitch climbing, UIAA II–III	Elbrus (Normal Route): 2A
3A–3B	UIAA III–IV, full-day routes	Moderate alpine routes
4A–4B	UIAA IV+, 1–2 day routes	Serious alpine climbs
5A–5B	UIAA V–VI, multi-day commitment	Peak Lenin, Pik Kommunizma: 5A
6A–6B	Extreme expeditions, sustained VI+	K2 Japanese Route: 6B

MountaineeringFrench Alpine Grades (F–ED)

The international standard for alpine mountaineering grades. Adopted by UIAA in 1967. Rates overall route difficulty including length, technical sections, and commitment level.

Grade	Name	Description
F	Facile (Easy)	Glacier hiking, easy scrambling. Rope optional.
PD	Peu Difficile	Basic climbing (Fr. 3–4), crevasse navigation, ≤45° snow/ice.
AD	Assez Difficile	Sustained climbing, 50°+ snow/ice. Belayed sections.
D	Difficile	Technical rock/ice (UIAA IV–V), up to 70° slopes.
TD	Très Difficile	Difficult climbing (Fr. 6), 80° ice. Very serious undertaking.
ED	Extrêmement Difficile	Extreme routes. Open-ended: ED1, ED2, ED3...

Note: + or - modifiers (e.g., PD+, AD-) add precision.

Approximate Comparison

Russian	French	UIAA Overall
1A–1B	F	I
2A–2B	PD	II
3A–3B	AD	III
4A–4B	D	IV
5A–5B	TD	V
6A–6B	ED	VI

This comparison is approximate. Russian grades include altitude as a factor; French grades do not. Routes may not fit neatly into these categories.

Important to Know

Conditions Change Everything

The same route can feel completely different in summer vs. winter, dry vs. wet conditions. Grades assume favorable conditions. Always check recent reports before your trip.

Grade ≠ Safety Guarantee

Even "easy" alpine routes can be dangerous. Rockfall, weather changes, and other objective hazards exist at all difficulty levels. A grade indicates technical difficulty, not safety.

Overall vs. Technical Grades

Alpine grades (1A–6B, F–ED) rate the whole route experience. Technical grades (UIAA, YDS) rate specific climbing moves. A route can be technically easy but still serious due to length or commitment.
