Brunkebergs tunnel is a 231-metre passage through a ridge in central Stockholm, linking David Bagares gata with Tunnelgatan. Visit Stockholm describes it as a shortcut for people walking or cycling. The route goes through the ridge rather than around it, so the tunnel itself is both a passage between the two streets and a place visitors can stop to see or photograph.

Visit Stockholm says the tunnel posed a difficult task for engineers in 1884. It was ready to welcome Stockholmers two years later, in 1886. The account gives those dates but no further detail about the engineering. The passage remains described as a shortcut for pedestrians and cyclists.

Visitors can walk or cycle through the 231-metre tunnel. Visit Stockholm calls it a classic Instagram spot. The page gives no admission price or opening hours, and it does not recommend how long to spend there. Its stated location is David Bagares gata–Tunnelgatan, Stockholm, so the two named street ends identify where the passage connects. The information provided does not specify whether operation changes by season.
