As we looked up at the castle perched above us the walk up looked a little daunting. In 34° heat we steadied ourselves and started walking anyway. In for a penny. A mixture of stairs and twisty gravel paths awaited us. At one point the path split and we had a 50/50 decision to make as it’s not sign posted. We chose the wrong path and after a couple on minutes we decided to turn around and go the other way. The climb was actually ok and not too taxing. We were very proud of ourselves. Near the top a booth greets you. After paying €5 each to enter the castle and a fair few more steps later we arrived at the Main tower. You find out it was actually a full on settlement of 120 rooms etc with a fair few more turrets to visit. The view is fantastic from all aspects and there are a few buildings explaining the history of the castle. As you finish your tour there is a little cafe that awaits you where you can get a well earned beer and some food as well as a toilet. The walk down is easy. It’s well worth a visit when you get to Arco as well as a look around the pretty town square etc.
Arco
Arco sits at the northern end of Lake Garda's reach, where the Sarca River has been cutting through limestone for longer than anyone has kept records. The town spent its 19th century as a winter cure destination for Central European aristocrats and tuberculosis patients alike — a fact that explains the Art Nouveau casino (now a library) and the particular hush of its palm-lined squares, which feel designed for slow afternoons rather than passing through.
Above everything, the Castello di Arco anchors the skyline from a volcanic rock. Inside its ruined walls, a 14th-century fresco cycle survived centuries of abandonment: knights playing chess, St. George and the dragon, a couple weaving rose garlands. That these images exist at all, recovered in a 1986 restoration, gives the climb a specific reason beyond the view.
💛 What travellers fall for
People who come back tend to mention the same two things: the fresco room in the castle, which rewards a second look once you know what you're looking at, and the Collegiata dell'Assunta on a quiet weekday morning, when the 17th-century nave is almost entirely yours. The walk between the two takes about ten minutes and passes Palazzo Marchetti, whose portal is attributed to Giulio Romano.

People have lived on this plain since the Neolithic, and the Cenomani tribes used the castle rock as a shelter around 300 BC. Roman origins are probable, though the ancient name remains debated. The first clear documentary record comes from the 12th century, when a Bavarian noble family took the castle — likely built originally in the era of Theodoric — and received feudal investiture from the Bishop of Trento, eventually Italianising their name to d'Arco.
The town passed through the hands of the Visconti, the Scaligeri, the Venetians, and finally the Habsburgs, before joining Italy after World War I. The castle itself was abandoned after a French siege in 1703, left to ruin until restoration work began in 1986. The late 19th century brought a different kind of transformation: Arco reinvented itself as a winter health resort, and the buildings of that era — the Art Nouveau casino, the grand hotels — still set the tone of the centre.

When to go
Summers are warm and manageable, with July averaging around 23°C and a chance of afternoon showers. Winters are cool rather than harsh — January lows can dip below freezing, but the town's historic role as a mild-winter retreat reflects a genuine microclimate that keeps things gentler than the alpine terrain suggests.

What travellers say about Arco
This is a truly magical place. The ruins of the castle are mesmerising on their own. However, when you add the incredible views and the vistas of the surrounding areas, the combination is truly amazing.
Lovely morning looking around the castle. Managed to get free entry with the Garda Guest card. It's a very steep walk up to the castle and around it. Lovely views from the top. We cycled from Riva. Left bikes in the old town at the bottom and walked up. Then walked back down for some well deserved lunch. Lovely day.
Went here as I saw the castle and the views were stunning, and they were. Be prepared for steep walks up however, it will test you (depending on your ability that is). There is a ticket office on entry and it is a reasonably low price, you can pay on card. The walk up might take about 20 minutes or so. If you are there in the spring or summer there is a nice breeze at the top.
A very stiff but beautiful climb from the old town of Arco. You park near the central piazza and go up the cobble streets up until you get to the mountain path. It’s about 30 minutes climb by foot. Bicycle trails also exists. The castle and the views of the town and surrounding mountains are worth it!
