The rock climbing spot Arimonda is suited near the Italian / French border about 50 kilometres North of Monaco.
The rock climbing on French Limestone is nice and even if there ain't many routes, it has together with other climbing spots nearby a lot to offer.
The view over the valley and several French and Italian summits reaching 3000 meters in the surrounding area makes a rock climbing day or two to a pleasant memory.
If you need more rock climbing routes then cross the border, in 15 minutes you reach the rock climbing spot Vernante / Fulchi and another 20 kilometres takes you to the rock climbing spot Andonno.
