Valcamonica is the valley of the rock carvings, and Sellero is one of the places where you can walk among them. For about eight thousand years, from the Stone Age to Roman times, the people who lived here, especially the Camuni of the Iron Age, hammered and scratched pictures onto the smooth glacier-polished rock: hunters, deer, warriors, farmers, ploughs, huts and strange symbols. The valley holds hundreds of thousands of them, and in 1979 it became Italy's first UNESCO World Heritage Site. The municipal park at Sellero preserves a group of engraved rocks in woodland above the Oglio river, so you walk on a path and find the carvings on bare sheets of stone among the trees.
What makes the carvings compelling is that they are not formal art. They show what people cared about: weapons, farming, ritual scenes, and the occasional picture of a house or a dancing figure. After rain the lichen and wet stone make them easier to read, and low raking light helps too, so early morning or late afternoon is the time to look. Be gentle, stay on the paths and never rub or touch the surface, as the engravings are fragile.
The valley is a fine ride. Valcamonica runs north from Lake Iseo for about 80 km, with the Adamello massif on one side and the Orobie Alps on the other. The main road is a busy valley road with traffic and a lot of small towns, so most riders use it as a connection to the passes: the Tonale at about 1,880 metres to the north-east, and the Gavia, a much more demanding high pass beyond Ponte di Legno, which is closed in winter and often opens only in early summer. Snow and fog can arrive quickly at height, so take layers.
Sellero is a small village of about a thousand people, with Cedegolo and Capo di Ponte a few kilometres away. Capo di Ponte has the largest cluster of carvings at Naquane and a number of simple places to eat. For fuel the valley towns have stations, but do not count on a small village, so top up in Capo di Ponte or farther down the valley around Darfo Boario Terme, which is the larger town. Try casoncelli, the local filled pasta with sage and butter, and a glass of Franciacorta if you are heading toward the lake.
