Via ferrata safety
Proper equipment, knowing the rules and knowing how to react in an emergency - safety underpins every outing.
Mandatory equipment
Via ferrata requires specific technical gear. None of these items are optional.
Harness
Harness certified to EN 12277 (type C). Must be correctly fitted and in good condition. Replace every 10 years or after a major fall.
Helmet
Climbing or mountaineering helmet certified to EN 12492. Protects against rockfall and impact in case of a fall.
Via ferrata lanyard
Y-shaped lanyard with two energy absorbers, certified to EN 958. Always stay clipped to the cable - never remove both carabiners at the same time.
Gloves
Via ferrata or climbing gloves. Protect the hands when sliding along cables and improve grip.
Suitable footwear
Hiking boots with stiff soles or climbing shoes. Essential for good grip on rock.
Water and food
Minimum 1.5 L of water per person depending on duration. The effort involved in via ferrata is intense and dehydration can occur quickly.
Via Ferrata Rating - understanding levels
Via ferrata routes are rated from K1 to K6 according to their technical and physical difficulty (Hüsler scale). This system is widely used across Europe and Switzerland.
AGenerally marked routes with generous protection. Natural ledges, ladders or footbridges where needed. Exposed sections secured by rope or chain.
BSteep terrain in places but very well protected. Near-vertical sections fitted with rungs or ladders. Cable or chain even in less difficult zones.
CWell-inclined rock with steep and sometimes exposed sections. Abundant protection. No sections requiring great arm strength.
DSteep to sometimes vertical terrain with short but secured overhangs. Very exposed route with few natural holds. Steel cable only at exposed sections - arm strength required. Exception: sport via ferratas 'a la francaise'.
EExtreme rocky terrain. Long, demanding and exhausting routes throughout. Some vertical sections protected only by cable. Reserved for experienced practitioners with good physical fitness.
FLong and poorly equipped sections on vertical terrain. Endurance and arm strength essential. For bold, well-trained individuals in excellent physical condition only.
The rating describes technical difficulty, not objective danger. A K2 via ferrata can become dangerous in poor weather conditions.
Hiking Rating - understanding levels
The Swiss Alpine Club (SAC) rates hikes from T1 to T6, from easy marked trails to extreme alpine terrain without paths. This scale is a reference across Europe.
Well-marked path or trail. Exposed sections very well secured. No specific requirements - route-finding straightforward, generally possible without a map.
Path with continuous route. Terrain sometimes steep. Risk of a fall cannot be excluded. Good balance and basic orientation skills required.
Path not always continuously visible. Steep terrain with some secured passages (ropes, chains). Scree, easy rocky slopes. Hands may occasionally be needed for balance. Sure-footed, moderate orientation, basic alpine experience.
Path traces only, often without a clear route. Demanding terrain with easy scrambling. Boulder fields, steep grassy slopes. Sure-footed, good orientation, alpine experience and basic knowledge of technical equipment.
Often without a path. Very demanding terrain with confirmed scrambling. Steep snowfields. Exposure over longer stretches. Very sure-footed, excellent orientation, in-depth alpine experience, good technical knowledge.
Mostly without a path. Particularly steep terrain with longer and demanding scrambling sections. Delicate snowfields. Very exposed over longer stretches. Perfectly sure-footed, proven alpine experience, confident use of technical equipment.
Routes are rated assuming favourable conditions (good weather, dry terrain, no snow). Modifiers + and - allow finer grading (e.g. T3+, T4-).
Essential rules on the route
These safety rules must be followed without exception.
Never remove both carabiners from the cable at the same time - always stay clipped in.
Maintain a safe distance from the climber ahead to avoid being struck by rockfall.
Never climb during a thunderstorm or when storm clouds are approaching - lightning risk on metal cables.
Follow the indicated direction of travel - some routes are one-way for safety reasons.
Do not overcrowd a single cable section. In case of a fall, the jolt can destabilise other climbers.
Never climb alone - always be accompanied or inform someone of your route and expected return time.
Check the condition of fixed equipment (cables, bolts, steps) before using it. Report any issues to the relevant authorities.
Children must be individually clipped in and supervised at all times by an experienced adult.
Weather and hazardous conditions
Weather conditions and the state of the rock are critical to your safety.
Thunderstorm / lightning
Lethal danger. Metal cables are excellent conductors. Descend immediately and move away from the cable if a storm approaches. Do not wait for rain to start.
Rain
Wet rock drastically reduces grip. Holds and steps become slippery. Strongly inadvisable except on routes equipped for wet conditions.
Snow and ice
Makes progress extremely dangerous or impossible. Cables and holds may be covered with invisible ice. Absolutely avoid.
Intense heat
Risk of heat stroke and dehydration. Carry enough water. Avoid the hottest hours (11am-3pm) in summer.
Rockfall
Wind, other climbers or thawing can trigger rockfall. Always wear a helmet and maintain a safe distance.
Before you go - checklist
Taking a few minutes to check these points could save your life.
Check the local weather forecast for the next 24 hours.
Verify that the via ferrata is open (opening period and current conditions).
Inspect all equipment: harness, lanyard, helmet, footwear.
Ensure you have enough water and food for the planned duration.
Inform someone of your destination, chosen route and expected return time.
Honestly assess your ability level against the route's rating.
Download the map or route card for offline use.
Charge your phone and note down emergency numbers.
Emergency numbers
Depending on the situation
Fall with serious injury
- Person hanging on the lanyard
- Fracture
- Head trauma
- Loss of consciousness
- Heavy bleeding
Person stuck / exhausted / panicking
Even without injury, mountain rescue can intervene if someone can no longer move forward or descend.
When calling emergency services: give your exact location (name of the via ferrata, canton, GPS coordinates if possible), the number of casualties, the nature of injuries and your phone number.
