I was foaming at the mouth when I saw the signs. But there again I have been driving over the pass at night only to have to swerve past the sheep sleeping on the road by the Ponderosa cafe.
Within 1 hour to the north is the Clwyd Gate at the top of Bwlch Pen Barras (A494 Ruthin-Mold road), gives you grand views of the Beautiful Vale of Clwyd. Ruthin is very photogenic with its concentration of historic buildings. North westwards, via Ruthin and Denbigh are the Denbighshire Moors - Gwylfa Hiraethog - the old Shooting Lodge by the Sportsman's Arms affords great views.
If anyone thinks the Horseshoe Pass is dangerous. The A494 down from Clwyd Gate towards Llanbedr and Ruthin is on another level, a long straight incline, dropping steadily and then suddenly an extremely sharp left hand bend followed by a sweeping right. Speed limits are there, as are bump strips in the road, for the unaware but locals who know the road know exactly when to brake....miss it and you're in someone's bedroom..
