The Ross Isles are two small islands in Loch Lomond, in west central Scotland.
They lie opposite Luss, and are named after the promontory on the east shore (ros meaning the same in Scottish Gaelic.), where Ross Priory is located.
The Pilot sank off here in 1850.
The islands have some vegetation but are mostly uninhabitable, with no suitable landing locations for boats to approach.
