Erbusaig Bay has a classic half circle shape, that faces the island of Scalpay, with the small twin Black Islands in the bottom half of the bay looking north, obscuring the view.

The southern plateau is the higher, rising to 215 feet, while the northern rock plateaux is slightly lower.

The west coast of Scotland close to Erbusaig Bay is highly fragmented and populated with many hundreds of small islets.

Access to the bay is by rail or the A87 road, which runs west from its junction with the A82 road at Invergarry (NH307011), along the north shores of Loch Garry and Loch Cluanie, then down through Glen Shiel and along Loch Duich to Kyle of Lochalsh before crossing the Skye Bridge to Kyleakin, Broadford, and Portree, and terminating at Uig in the north of the Isle of Skye.

An unnamed B road leaves the A87 at Kyle of Lochalsh, and travels north passing the bay.
