Duration in hours
Distance in km
Suggested period

The “Defensionmauer” was the defensive wall built before WWI in the area of Sperone against possible attacks by the Italian infantry and was armed with machine guns.  

The path to reach the first trenches is easy but a little bit exposed; there are a big embrasure excavated in the rock, the entrance of a gallery (be careful and have a torch if you visit it) and all around trenches and rock walls. 

After that, starts the Defensionmauer, a trail digged in the mountain side and if necessary covered by concrete to hide it from the enemy. The several openings allowed the Austrian to dominate the valley and fire the Italians on the other mountain side.

Safety guidelines

Safety Tips

  1. Choose itineraries that suit your physical and technical abilities. Collect information about the area you are visiting and the trail’s conditions and get a detailed trekking map.
  2. Wear clothes and take equipment that suit the difficulty and length of your tour. Keep emergency gear in your rucksack, including first aid supplies.
  3. Do not go walking alone in the mountains. In any case, tell someone where you are going and report back on returning.
  4. Look at the weather forecast before setting off and always keep an eye on the weather.
  5. In case of doubt, go back. It is better to give up than risk bad weather or face difficulties beyond your strength, ability and equipment.
  6. Do not leave marked paths and do not take shortcuts.
  7. All described walks are in a natural environment and therefore their use is at your own risk.

This information is subject to inevitable variations, so none of these indications are absolute. It is not entirely possible to avoid giving inexact or imprecise information, given how quickly environmental and weather conditions can change. For this reason, we decline any responsibility for changes which the user may encounter. In any case, it is advisable to check environment and weather conditions before setting out.

You need to wear the right clothing and take the proper gear when you go hiking in the mountains. Even on relatively short easy outings make sure to take all you need so you don't run into trouble if things take an unexpected turn, for example a storm blows up or you have a sudden drop in energy levels.

What should you take when you go on a hike?

Your rucksack (for a day trip a 25/30L capacity should do) should contain:

  • water canteen (1L)
  • snacks (e.g. mixed dried fruit or chocolate)
  • First aid kit
  • windproof jacket
  • fleece
  • change of t-shirt and socks (in a plastic bag)
  • make sure to wear or at least bring a pair of long trousers
  • hat
  • sun screen
  • sunglasses
  • gloves
  • whistle to attract attention in an emergency


Make sure you're wearing the right footwear for the trail and season. The going can get rough and rocky underfoot and a pair of hiking boots will protect you from sprains. When wet, a grassy slope, rocky slab or steep trail can be dangerous unless you are wearing the proper footwear.

And finally... don't forget to bring your camera! You'll need it to capture the stunning views you come across all over Garda Trentino. And if you like, you can share your memories with us at #GardaTrentino.
