It is one of several lochs in Glen Affric, a National Nature Reserve within Scotland's Caledonian Forest.

[1] The loch is named after the mountain on its northwest shore, Beinn a' Mheadhoin, which translates from Scottish Gaelic to "Middle Mountain".

[2] The Affric-Kintail Way runs along the loch's south shore.

In 2016, Scottish rewilding charity Trees for Life planted aspen along Loch Beinn a' Mheadhoin's shores to support the reintroduction of beavers.

[3] The loch was partially expanded in the 1950s as part of the Affric-Beauly hydro-electric power scheme, drawing water from Loch Mullardoch to the north via a 5.5 km long tunnel.
