First, you hike direction south along the river into the Vallone di Seiva. Either you cross the river at the beginning and walk on the left (western) side of the river or you go along the easter side up to the sign Rifugio Vittorio Emanuele, both is possible. The Rifugio is a great base to climb the Gran Paradiso in two days.
At the sign you head on for a few minutes and then you go to the East, following the summer trail into the forest. After around 100 altimeters you leave the forest and go on, quite steeply through hilly terrain, till you reach the hut Rifugio Vittorio Emanuele. Here you can get some food before entering the high alpine area of Gran Paradiso and head on with lots of people up to the peak.
If you are lucky and there are no tracks, you just pass the hut and afterwards you go to the left, direction North, until you reach the morain. From here you go on in long snake-like curves up to the Gran Paradiso Glacier and to the peak.
You will see the prominent Schiena d´Asino, where the uphill tracks from Rifugio Chabod meet the ones of Vittorio Emanuele, it is on a height of around 3500 meters. Having a beautiful view to the ice boom (if the weather is fine) you go on direction South-East up to the "Back of the Donkey" where usually are lots of crevasses and then to the Col d. Becca di Moncorvè. At this point you often have lots of clowds coming in over the saddle and some wind. In a left curve you move on to the steeper section, direction North, and then further up to the main crevasse which is almost every winter closed by lots of snow. Then you reach the Ski- or Splitboard Depot. From here it is just 60 meters further up to reach the summit, but you have to climb a bit (UIAA I-II). After an exposed step you will be just beside the Madonna enjoying the breathtaking views to the big neighbors like Matterhorn, Mont Blanc, Monte Rosa... and there is rising this feeling in your soul...
The time is estimated with 8+ hours when you go slowly and have a lunch break at the peak and another break at the hut.
If the conditions are right and your skills accordingly, you can find great untracked ascents aside to watch the caraavan hiking up from a distance. Later you get easyly back to the track to safe strength for the descent.
As ascent, if you open your eyes and ears you can find some excellent untracked descent options which make this classic an unforgettable experience.
Please take care even when it looks great, you are moving on high alpine area and you should be aware of the possible dangers. Also you should minimize your risk and choose your line carefully.
Alternative I Check out the way down to Rifugio F. Chabod.
Alternative II, if you hike up 150 altimeters again, you can reach the Col del Grant Etret at 3200 meter and ride down to Pont on this less tracked way. Keep in mind the steep walls of the mountains you are traversing.
