Needle Eye Rock is the tallest sea arch in the UK, yet probably the least well-known!
This relatively unknown sea arch would probably rank amongst Caithness' most impressive natural wonders if it wasn't for its remoteness. Just a few kilometres north of the abandoned Sarclet Harbour, this natural rock formation comprises a tall sea arch that resembles the eye of a needle, still joined to the mainland by a narrow rock promontory. Caused my natural erosional processes by the sea below, Needle Eye Rock stands approximately 45m in height.
At 45m high, Needle Eye Rock is the UK's tallest sea arch!
