What a great little castle. Amazing to see it still standing after so many years. Very cool little place to visit and explore the ruins - never quite seen anything like it.

Keiss Castle – Ruin on the Edge of the World This 16th-century tower ruin teeters spectacularly on a cliff above Sinclair’s Bay, just outside the village of Keiss. The walk to it (approx. 2km return) starts at the harbour and takes you past abandoned brochs, coastal defences and rugged beach scenery. You can spot seals, otters and seabirds along the way. The ruin itself is not accessible, but the views are unforgettable.

Bucholie Castle – Forgotten ruin on a cliff edge One of Caithness’s most dramatic, yet least visited castles, this 15th-century ruin sits on a narrow headland overlooking the North Sea, a few miles south of John O’Groats. The walk to it (approx. 20 mins from the A99) takes you across quiet meadows and ends with a spectacular view of the remains.

The romantic ruins of the old Keiss Castle right on the cliff are very easy to reach from Keiss Harbour. You can't get past the new Keiss Castle, the owner has locked the gates to the road.

This is all on main roads and we are monitoring it to see if we can find a better route.

The parking lot at Castle Sinclair does not have any sanitary facilities, but it is permitted to spend the night here (once) - and this is also used a lot! The sunrise and sunset are certainly spectacular... The parking fees are moderate - and according to the sign, they are not even enforced (so they are voluntary).
