Firkin Point C is a backcountry camping area on the western shore of Loch Lomond, operated by the Loch Lomond & The Trossachs National Park Authority.

Camping bylaws are in effect from March to September, and a permit must be obtained in advance through the National Park's pre-booking system.

There are no designated pitches; instead, advance reservations are used to manage visitor numbers and keep the experience uncrowded. Campers enjoy open views across the loch toward Ben Lomond.

The site sits along the West Lomond Cycle Path, which runs between Balloch and Tarbet.
