What is Trekking?
Types and differences.

Trekking is more than just walking: it's a way of exploring nature at your own pace. Knowing what it really means and how it differs from similar activities helps you choose the right experience and enjoy every step.

What is trekking?

The word comes from the English verb to trek, meaning "to make a long journey on foot".
Today it refers to a structured hike on trails, in the mountains or in natural environments, with a physical commitment that goes beyond a simple walk.

Trekkers choose their route, pack their backpack and set off with the right gear. It's a way of being in nature that asks for attention, and gives back a lot in return. A true trek shares a few key elements:

• A clear itinerary, planned before setting out;
• Real elevation gain, which requires effort and training;
• Natural terrain: trails, rock, meadows, forest;
• Variable duration, from a few hours to several days;
• Purposeful gear: technical footwear, backpack, thermal layer, water and food.

Trekking, walking and hiking.
What's the difference?

These terms are often used as synonyms, but they describe different experiences.

Walking is the simplest activity: you can do it anywhere, without specific gear, for everyday wellbeing.

Hiking instead takes you into hills or mountains along marked trails, usually for a day.

Trekking asks for more: greater autonomy, deeper preparation, more demanding environments and often several days on the move.

The key difference between hiking and trekking is hence time: hiking refers to a one-day outing, while trekking is a walking journey that lasts several days, with overnights in mountain huts, bivouacs or tents. Every trek includes hiking sections, but not every hike is a trek.

Trekking and trail running.
Two ways to live the trail

Trekking and trail running share the same terrain, but read it in opposite ways.

Trekking is about pace, observation and duration.
Trail running is running in nature: lightness, speed, shorter times.

What really changes:

Pace: steady walking vs. running;
Length: hours or days vs. short, intense sessions;
Backpack: full and roomy vs. minimal running vest;
Footwear: sturdy trekking shoes with ankle support vs. light, flexible trail shoes;
Approach: the journey vs. performance and training.

Trekking and Trail Running. Two different disciplines, not rivals: many enthusiasts switch between them depending on season, fitness and mood.

The main types of trekking

Every trek has its own character.
Duration, altitude and environment change from one to the next. The most common forms:

Day trekking: a single day, no overnight. The best way to start or to train for longer routes. A 10–20 litre backpack, trekking shoes, water, snacks and a spare technical layer are enough.

Multi-day trekking
: several consecutive days with overnights in mountain huts, bivouacs or tents. It calls for real planning and a 40–60 litre backpack. Iconic Italian routes include the Alta Via delle Dolomiti, the Sentiero Italia CAI and the Tour du Mont Blanc.

High-altitude trekking: above 2,500–3,000 metres, where the air gets thinner and the weather changes quickly. It requires acclimatisation, experience and technical gear like micro-crampons, poles and thermal layers.

Urban trekking: walking through cities and historic centres along themed routes — historical, artistic, gastronomic. No technical element, but the same spirit: discovering a place at a slower pace.

How to choose the right trek

Which trek is right for you?

It depends on three things: your fitness level, the time you have (a few hours, one day or several) and your mountain experience (navigation, weather reading, terrain handling).
The advice is simple: start with day outings on marked trails, build up gradually and reach the tougher challenges well prepared.

A useful reference is the Italian Alpine Club (CAI) scale:

T (Tourist, easy routes for everyone),
E (Hiking, well-marked trails of moderate difficulty),
EE (Expert Hikers, exposed or demanding terrain) and
EEA (Expert Hikers with Equipment, via ferrata and equipped passages).

Starting from T or E routes builds a solid base before moving on to more technical itineraries.

Frequently Asked Questions

What's the best season for trekking?

For high altitude in Italy, the ideal window is June to September. In hills and mid-mountain areas, you can trek all year round, checking weather and conditions.

Can you go trekking alone?

On easy, well-marked trails, yes, but with the right care: always let someone know your route, check the weather and carry the essentials. On demanding routes or at high altitude, it's better to go with a partner or a guide.

How many kilometres do you cover in a day?

On average, a day of trekking covers 10 to 20 km, with 500 to 1,500 metres of elevation gain. It's not the distance that makes the difference, but the pace you set.

Do you need to be fit to go trekking?

For an easy day outing, a good basic fitness level is enough. For multi-day treks or high-altitude routes, you need steadier training: long walks with a backpack and regular aerobic activity.

What's the difference between trekking and mountaineering?

Trekking takes place on trails and non-technical terrain, without ropes or harnesses. Mountaineering means moving on rock, ice or mixed terrain, with specialised gear and dedicated safety skills.
