Osiglia is roughly 25 kilometres inland from the Riviera coast at Finale Ligure, reached by a narrow mountain road that climbs the upper Bormida valley. The drive is slow but scenic, with switchbacks and stretches of beech and chestnut forest. There is no train station in the village; the nearest railway is at Millesimo or Calizzano, both of which require an onward bus or taxi.
In summer, weekend visitors from Savona and Genoa make the trip up for the cooler temperatures and the lake. The road is straightforward in good weather but should be avoided after heavy rain, when stretches can be affected by landslides.
