The village lies at the north-eastern edge of the Lake, at the junction of the A81 road with the B8034 road, which runs south, just to the west of Flanders Moss, to meet the A811 road at Arnprior. The elevation is around 25 m above sea level. The country around is generally low-lying, except to the north where the Menteith Hills rise, including Beinn Dearg (426 m), with the Trossachs and the southern Highlands beyond. The Parish includes the outlying settlements of Coblehead, Dykehead, Gartmore and Ruskie.

In the summer months a ferry runs from Port of Menteith to the island of Inchmahome, site of the Historic Scotland-maintained Inchmahome Priory. The village is home to a fishing club and is the starting point for anglers on the Lake of Menteith. Nick Nairn's cookery school is based at Loch End, just south of Port of Menteith at the south-east corner of the Lake.
