Loch Achray South is a designated camping permit area within Loch Lomond & The Trossachs National Park, situated on the shores of Loch Achray in the Scottish Trossachs.

Camping Management Byelaws are in effect here from 1 March to 30 September each year, during which a permit is required to camp in this zone.

Permits can be booked up to four weeks in advance through the National Park Authority and allow camping anywhere within the designated permit area.

The byelaws exist to protect the lochshore environment and promote responsible enjoyment of this popular location. Outside the byelaw season, Scotland's access legislation permits responsible wild camping in accordance with the Scottish Outdoor Access Code.
