This trail focuses on some of the typical features of the Garda area, and all with a view of the lake. From Torbole, the trail runs past the glacial potholes and then heads up to the Castegneto chestnut wood, where you have a wonderful view of Torbole and the lake below.
Watch out because the stretch leading up the chestnut wood is short but quite steep!

Safety information

The information on this chart is subject to inevitable variations, so this means that none of the 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,  the hiker is advised to check the conditions of the places, environment and weather before setting out.


You need to be wearing 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?

What you should have in your rucksack (for a day trip a 25/30L capacity should do):

  • 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
  • emergency telephone number: 112

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.

Tips, hints and links

  •  The Monte Corno area where the Castagneto chestnut wood is situated was on the Front held by the imperial Austro-Hungarian army during the First World War: there are still stretches of trenches and various buildings restored by local associations which are open to visitors. For anybody interested in visiting these trenches, you can follow signposts in the area and then head back down to Nago on trail SAT 637.
  • The Marmitte dei Giganti are glacial potholes (known as the Giants' Potholes) formed millions of years ago by the erosion of the rock. These great cavities have a diameter of 4 or 5 metres and are as deep as 12 metres. The potholes were formed by the melting of the glaciers which modelled the rock and polished its surface. The potholes often occur together with other natural karst phenomena such as striated rock, sheepbacks and glacial shift.

  • The sweet chestnut tree was widely grown in Trentino as elsewhere because of the major economic importance it had for mountain people who depended on it as a subsistence food. The fruit of this tree is highly nutritious and formed an important part of the local diet. Testimony to this are the numerous chestnut woods in Garda Trentino, including those in Drena, Pranzo, Tenno and Campi. Today the "maroni" (larger and tastier than normal chestnuts) play a major part in the menu for festivals and speciality menus for the autumn season. Info:

Turn-by-turn directions

Head north from the centre of Torbole along via Strada Granda where the path begins which leads up the valley at the foot of a high limestone wall to the glacial potholes. Cross the main road and continue uphill along the dirt track which goes to Nago. When you come out at the roundabout, take the trail on the left for Castagneto (uphill towards the residence Nido d'Aquila) which climbs up the slopes of Monte Perlone. On your right, on the Nago side, you will come across other interesting glacial potholes.
