Prati di Tivo in Gran Sasso is busy in the summer with hikers, tourists enjoying beer at bars with views of Corno Grande, and children jumping here and there in the rope park.
During our five-day stay in Prati, we did three long trails and some shorter. And because we both like waterfalls, one of them was an easy hike in Gran Sasso to Cascata del Rio Arno.

Easy Hike in Gran Sasso – the Trail from Prati di Tivo to Val Maone
We stayed at Orto Bianco Residence; from there, the path to the cascata starts on the right, on the way to the main Prati square, Piazzale Amorocchi. According to the well-visible sign (100D path), the hike takes 40 min.
With our super sandwiches and water in backpacks, we started hiking through Val Maone. For several hundred meters, the path is open, which is great if you want to get a tan. I didn’t want to get any browner, so I applied sunblockers and wore a hat.
On Trail 100D: Sun, Shade, and Bear Thoughts in Gran Sasso
Walking, we got to the forest; on both sides of a wide, well-trodden path, trees are growing, providing sweating hikers walking up (i.e., myself) with shade, but even so, it was hot.
The rest of the trail is wide, mainly gravel-surfaced, and, like in the mountains, it runs up and down. Even if there are some rather steep sections, the path is absolutely suitable for beginners and casual walkers.
You can even bring your kids or grandparents to this family-friendly trail in Abruzzo; just remember there are some more challenging (at certain ages) parts.
At some point I felt that I was going up the hill at a 45-degree angle, but it was only a feeling. If that were really the case, I’d rather gracefully roll down than scramble up the hill.
The views on the way were great: I love Abruzzo, so not very objectively I state that the mountains are beautiful; grey rocks, grassy plateaus, woods and blooming plants.
From time to time a hawk or other falcon flies overhead, and chamois jump on the slopes. I would say it’s magic, but bears are always somewhere on my mind. Even if they rarely visit Gran Sasso. It’s just my bear mania, which, in a way, never allows me fully enjoy the mountains. Hm, maybe it’s time to visit a therapist.
Cascata del Rio Arno: The Taped-Off Path and a Tiny Trickle
We walked up to a small stream with drinkable water and huge stones lying around. According to the sign, the waterfall should be on the left. After a few meters down, we saw hanging tape blocking the way. But the tape can’t really block/close the way, can it? Of course we wanted to see the waterfall anyway, just decided to be cautious (who knows what was waiting on the way?). Anyway, I don’t advise crossing any lines/tapes.
After several steps, we realised that there were some construction works. The waterfall,with an emphasis on less, was more or less visible, and it was very small. Unbelievable—such a long name for a small waterfall trickling sluggishly down from the mountains. Disappointing.
Beyond the First Fall: Rio Arno Riverbed, Wildflowers, and Avalanche Ruins
But it’s Abruzzo, so even if something lets you down, there has to be something that gives you an opposite impression. And there was. We got back to the rivulet and crossed it and headed up.
After a short walk, we saw the upper reaches of the stream. It was just amazing – crystal-clear water flows through the canyon, winding its way among the boulders. The banks of the stream are lined with colourful, blooming plants—and they do the trick. The mixture of water, rock, and colours of the flowers is simply beautiful. Well, just the magic of this region of Italy.
Hiking along the Rio Arno riverbed, I came to the conclusion that nature keeps hikers grounded, preventing them from becoming too dizzy from the beautiful views. I mean, it’s enough to see its power; and even if you feel like doing something reckless in the mountains, it’s better not to—unless, of course, your dream is to be commemorated with a Darwin Award.
On the way, we saw hundreds of fallen trees and massive stones lying here and there. It looked like a landscape after an avalanche – stones had snapped the trunks rather than pulling them up by the roots. It was definitely an avalanche.
And beneath one of those trees—barely clinging to the ground and weighed down by a massive rock—two young ladies in ballerina shoes were having a photo session. Well, why not.
Further ahead, a massive trunk was blocking the path along the stream. Being in a not-very-hiking-like mood, I actually hoped there was no passage, and we would stay at the stream enjoying the water and colours. No way, Mauro found the path.
It became wider, steeper, and densely ‘decorated’ with branches. At some point we saw a wee rivulet springing up between stones. It looked as if somebody turned the tap upside down.
Funny, but instead of the inverted tap, there should be another cascade there. But there were just rocks – snow gliding downhill had blocked the stream and killed the waterfall. Second disappointment this day. Unbelievable.
Cascata or Cascate? Finding the Hidden Falls and the Canyon “Pier”
It’s not nice to end a hike regretting it, so instead of wandering among the remnants of an avalanche, we went back to the ‘flowery’ stream; in such a setting, even slightly stale sandwiches tasted good.
Going down, on the left we saw a narrow (not very narrow though) wall going into the canyon; it looked like a mountain pier. From there you can see another two waterfalls.
Being honest, I was a bit confused by all these waterfalls. The torrent itself is called Rio Arno; the main waterfall, i.e. the one with the blocked path, actually was not the nicest one. Maybe with high water it is more impressive. I saw four or five falls along the path, so the track should be called Cascate (cascata is singular) Rio Arno.
Even with the sight of fallen trees and dead waterfalls, the hike was not bad. I burned calories, enjoyed a beautiful torrent, amazing mountains, and saw what happens when nature goes crazy.
The path is good if you don’t want to climb a lot, but you still want to move. The route takes 40 min-1 h, but if you decide to spend time just sitting on the bank of the river, it can easily turn into an easy day hike in Gran Sasso.
I think maybe in May (if there’s no snow) or at the beginning of June, the torrent is full of water, so it might be the best time to visit the Rio Arno waterfall(s)
Practical Tips: Rio Arno Hike at a Glance (Distance, Parking, and Best Time)
- The trail takes about 40 minutes to 1 hour one way (roughly 4–5 km return), depends on your speed,
- You have to climb max up to 150 m (the path goes further up if you want to continue)
- The path goes partly in the sun, so in the summer a hat and the sun blocker are useful
- Drinkable mountain water at the stream/fountain along the way, but carry a bottle regardless.
- People walk dogs in the forested sections, but I wouldn’t recommend bringing them all the way to the falls, because of the surface and the national park rules.
