Mountains have long been the ideal destination for hiking enthusiasts, not only for their stunning landscapes and natural beauty, but also for the spirit of friendship and camaraderie that unites walkers on the trail.
An ever-growing number of people are discovering this world, passing on their passion to their children or sharing it with friends. There are countless trails and treks just an hour or two's drive from wherever you live. You can find plenty of information online or from local tourist offices as well.
But how do you know if a trail is right for you?
To help you choose, you can use the hiking difficulty scale. Created by the CAI (Italian Alpine Club) to consistently categorise trails, it's based on three main parameters:
- Elevation gain: the total cumulative ascent and descent
- Distance: the straight-line distance from point A to point B on the map, without accounting for elevation. GPS tracks, however, factor in elevation and show the actual kilometres you'll walk.
- Trail marking: usually consists of signs indicating the location, estimated walking time, and trail number (waymark), and is typically marked with the distinctive red and white blazes on rocks and trees along the route.
Based on these factors, there are five hiking difficulty levels: Tourist, Hiking, Experienced Hikers, Experienced Hikers with Equipment, and Experienced Hikers with Ice Equipment. Here we'll cover only the first three, as the higher levels require ropes, harnesses, helmets, and specialised equipment like crampons and ice axes.
First level: Tourist (T)
Let's start with the first level, which includes most people who've recently discovered hiking and are still getting comfortable with mountains. I'm talking about the Tourist level, marked with the letter T on most trail information sheets. These routes feature simple, short, well-marked paths with under 500 m elevation gain. They often follow old mule tracks and established paths that are easy to navigate. You won't need strong navigation skills or intense training. These are trails suitable for everyone—children, seniors, and those with a more sedentary lifestyle can all enjoy them. It's the perfect chance for a day out combining sport, nature, and relaxation.
The second level is Hiking (E)
Here, the elevation gain increases to between 500 and 1000 m. While the path remains well-marked, the terrain becomes more challenging—both in terms of ground conditions and distance—and requires better fitness levels. You'll need more specialised mountain gear and improved navigation skills. If you can comfortably walk uphill for a couple of hours without difficulty, this level might be right for you.
The third level is for Experienced Hikers (EE)
At this level, knowing the mountains is essential. Trails exceed 1000 m of elevation gain, so you need to be in excellent physical condition and prepared for any type of terrain—steep slopes, scree fields, and exposed sections. Trail marking won't always be present, so you'll need strong navigation skills, the ability to follow faint traces on the ground, and crucially, you must be able to read a topographic map so you always know your location and what's nearby in case of emergency. Specialised climbing equipment isn't yet required at this level.
Now you have all the information you need to choose the right trail for you. If you're caught between two levels, don't hesitate to try the more challenging one, but be prepared to turn back if you realise it's still too demanding.
