Loch Avon lies in a deep cliff ringed trench between Cairn Gorm and Ben Macdui. This is one of the most inaccessible places in the Cairngorms.
The Loch has several beaches of fine sand and stretches for over one and a half miles. Streams fall headlong over dark head wall cliffs into the burn running into the western end of the Loch.
To the east lie Upper Glenavon and the arctic plateaux of Ben Avon and Ben a' Bhuird.
