HikeBuddy Hike Difficulty System

The Hike Difficulty System on HikeBuddy helps hikers easily understand the challenge level of every trail before setting out on their adventure. Based on the official SAC (Swiss Alpine Club) hiking scale, our color-coded guide provides a clear and consistent reference across Europe.

Please note: All trail classifications on HikeBuddy are added by individual users and are not verified by the platform.
We recommend checking official trail maps, signs, and local conditions before your hike.

Color-Based Trail Classification (Simplified)

Color	Trail Name (EN)	User Level	SAC Equivalent
🔵 Blue	Easy hike	Beginners, families	T1
🔴 Red	Moderate hike	Regular hikers	T2–T3
⚫ Black	Difficult hike	Experienced hikers, mountaineers	T4–T5
🏔️ Alpine	Alpine route	Expert alpinists, glacier travel, rope needed	T6

Understanding Hiking Trail Difficulties: The SAC Scale

The SAC Hiking Scale is the standard in all German-speaking countries denoting the difficulty of all paths, hiking ways, and trails. Developed by the Swiss Alpine Club, it takes surface, gradients, exposure, experience and gear required, and safety precautions into account.

Grade	Trail Type	Description
T1	Hiking Trails	Well-cleared trails with no major challenges. Compact surface, gentle gradients, no risk of falling.
T2	Mountaineering Trails	Well-marked trails with occasional steep sections. Slight risk of falling.
T3	Demanding Mountaineering Trails	Trails may be steep and exposed. Chains or ropes are often provided. Higher risk of falling.
T4	Alpine Hiking Trails	Trails may be unmarked. Includes gravel, glaciers, or steep terrain. Constant exposure risk.
T5	Demanding Alpine Hiking Trails	No clear path. Includes rocky slopes, glaciers, and technically challenging terrain. Gear like ropes/ice axe may be needed.
T6	Advanced Alpine Hiking Trails	Unmarked and includes climbing (UIAA grade II). Very steep, icy, or glacial. High risk. Advanced alpine gear required.

Difficulty Levels of Mountain Trails: The SAC Hiking and Alpine Hiking Scale

The SAC Hiking Scale was developed by the Swiss Alpine Club (SAC) and is the standard for rating mountain hiking trails in all German-speaking countries. It evaluates the nature of the terrain, the exposure of the trail, and the technical equipment and experience required for safe passage. Hiking associations use different rating systems. In Switzerland, the Swiss Hiking Trails (SWW) system is common, while in Germany and Austria, the German Alpine Club (DAV) system is often used.

• T1 – Hiking, Easy Valley Trail: Well-developed path. If exposed sections are present, they are very well secured. Danger of falling can largely be ruled out with normal behavior. Suitable even with regular sports shoes. Orientation is straightforward, usually possible even without a map.
• T2 – Mountain Hiking, Easy Mountain Trail: Continuous trail path. Terrain partly steep; risk of falling cannot be entirely excluded. Some surefootedness required; trekking shoes recommended. Basic orientation skills needed.
• T3 – Demanding Mountain Hiking, Moderate Mountain Trail: Trail may not always be clearly visible on the ground. Exposed sections may be secured with ropes or chains. Hands may be needed for balance. Some exposed areas with risk of falling, scree fields, pathless rocky terrain. Good surefootedness and sturdy trekking shoes required. Average orientation skills. Basic alpine experience.
• T4 – Alpine Hiking, Difficult Mountain Trail: Trail markings may not be present. In some sections, hands are needed for progression. Terrain is often exposed, includes tricky grassy slopes and rugged terrain. In high alpine areas possibly simple snowfields and bare glacier crossings. Familiarity with exposed terrain required. Stable trekking boots. Ability to assess terrain and good orientation skills necessary. Alpine experience required. Retreat can be difficult in case of sudden weather changes. Trail markings: blue (Switzerland), black (Germany, Austria).
• T5 – Demanding Alpine Hiking, Difficult Mountain Trail: Often no trail present. Occasional easy climbing sections. Exposed and challenging terrain, steep rocky slopes. In high alpine areas, possibly bare glaciers and snowfields with slipping danger. Mountain boots required. Confident terrain assessment and very good orientation skills needed. Solid alpine experience in high mountain terrain. Basic knowledge in the use of ice axe and rope. Trail markings: blue (CH), black (D, A).
• T6 – Difficult Alpine Hiking, Severe Mountain Trail: Mostly no trail. Climbing sections up to UIAA grade II. Frequently very exposed. Tricky rugged terrain. Bare glaciers with high risk of slipping. Usually not marked. Excellent orientation skills. Advanced alpine experience and proficiency in using technical alpine equipment. Usually unmarked.
