Leave Inversnaid and pass through the RSPB reserve and near Rob Roy's Cave before reaching Inverarnan on an undulating path.
The path from Inversnaid to the head of the loch is undulating with a generally rough surface. After passing Doune Bothy the path improves but it may seem a long two miles from Ardleish to Inverarnan. If you are staying across the water at Ardlui, look out for the sign pointing to the little ferry (2 miles before the end of this section). Walk down to the loch shore and call the ferry by raising the ball (you'll be returned to this same spot the following day). Otherwise, Beinglas Farm marks the end of your day. Leave the way and follow the signs for Inverarnan.
