    This stage takes you along the final stretch of the Dyke, past two enchanting castles, and over the ‘stream in the sky’.

    The trail voyages into the Clwydian Range Area of Outstanding Natural Beauty on this hike, which remains the case until its ultimate conclusion in Prestatyn.

    From Castle Mill, it is a short but sharp ascent to Chirk Castle, which was completed in 1310 during the reign of Edward I.

    You then hike east briefly to pick-up the Llangollen Canal. After a few miles following the canal you make an epic crossing over the River Dee via Pontcysyllte Aqueduct.

    Known as the ‘stream in the sky’, Pontcysyllte Aqueduct is an 18-arched structure that was completed in 1805. At the time, it was the longest aqueduct in Great Britain and the highest canal aqueduct in the world

    You depart from the canal at Trefor and climb through farmland and woodland back into the hills.

    It is well worth a short detour to see Castell Dinas Brân, an enchanting 13th-century ruin sat atop a rugged and prominent hilltop with wonderful views.

    This stage finishes in Llandegla, which has some options for accommodation and food and drink.
