Ardvreck Castle, Loch Assynt

A ruined 15th-century keep on a spit jutting into Loch Assynt, with Quinag's sandstone ridges behind — Ardvreck is a complete aerial composition waiting for you when you arrive. Park in the layby car park on the A837 and you are a two-minute walk from a clean launch on the loch shore. The classic move is a slow rising reveal from behind the ruin with Quinag filling the background, or a high top-down of the spit showing how the castle sits in the water. Light works both ends of the day: sunrise puts soft light on Quinag, sunset backlights the castle from the west end of the loch. This is one of the more relaxed Highland flights legally — the ruin is not an HES-managed property, the surrounding land is open access, and there is no FRZ within a very long way (Inverness is around 80km southeast). It gets a steady trickle of NC500 traffic in summer, so mid-day flights will have people wandering the ruin; go early and you will likely have it alone. Watch the wind funnelling down the loch between the hills — it can be flat calm at the car park and lively at 60m. Midges in still summer evenings are ferocious here; a breeze is your friend. Combine it with the old Calda House ruin next door for a second subject.
