Ben Tee is a hill with few outstanding geographical features, it has a broad grassy eastern ridge which sweeps down to the northern end of Loch Lochy and the Laggan lochs and gives one of the most popular approaches to the mountain. The southern slopes of the mountain drop very steeply to the valley of the Allt a' Choire Ghlais, a stream which drains eastwards entering a steeply wooded gorge where it changes its name to the Kilfinnan Burn. The gorge contains the Kilfillan Falls, a series of waterfalls, as the burn drains to the Great Glen at the north end of Loch Lochy.
