A lovely market town with pubs and shops and bakeries. Hilly routes into town but a number of good places for a stop mid ride.

The Moel Arthur climb from the Hendre side is a legendary North Wales brute: short but savagely steep. Prepare for an immediate, intense assault on an extremely narrow lane, averaging a punishing 10-13% but hitting vicious ramps, particularly on bends, well over 20% and reportedly reaching towards 25%. Reaching the exposed summit pass by the ancient Moel Arthur hill fort brings immense relief after conquering this notorious Clwydian Range wall.

Savage climb for which I’d recommend at least a 32t on rear. Oh and not doing it on a loaded bike😫 But what a view! And very few cars. Always a bonus. Relatively narrow tarmac. Bit gravelly nearer the bottom but gets smooth and dry once above the trees.

Complete knackered after this one and cars get very close.

The castle passed between various owners in the first half of the 14th century, before coming under the control of the Mortimer family. Meanwhile, the walled town had proved impractical to live in, and a newer, much larger, settlement developed outside the defences. In 1400, the walled town was raided during the Glyndŵr Rising, although the castle itself remained secure throughout the rebellion. During the Wars of the Roses, Denbigh was attacked by Lancastrian forces; the walled town was attacked and burnt. In the aftermath, the old town was largely abandoned by its inhabitants, the walled area becoming an extension of the castle's defences.

Denbigh Castle and town walls (/ˈdɛnbi/ DEN-bee; Welsh: Castell Dinbych a waliau tref [ˌkastɛɬ ˈdɪnbɨχ]) were built to control the lordship of Denbigh after the Conquest of Wales by Edward I of England in 1282. The lands were granted to Henry de Lacy, Earl of Lincoln, who began to build a new walled town, colonised by immigrants from England, protected by a substantial castle and surrounded by deer parks for hunting. The work had not been completed by 1294, when the Welsh temporarily seized the castle during the Madog ap Llywelyn revolt. The defences continued to be improved, although the castle was not completely finished by the time of Henry's death in 1311.

It’s a pretty tough climb popular with cyclists. There are 2 routes to reach the pass. From the west side (from Llanbedr-Dyffryn-Clwyd) the road gains 260 metres (853 feet) in altitude in just 2.25km (1.4 miles), the first half of which is at a gradient approaching 25%, followed by an even-steeper hairpin bend before the gradient finally eases slightly. More than two kilometres in length, the climb is introduced softly but very quickly begins to rise steeply, reaching a fearsome crescendo as it bends left on a huge 25 per cent hairpin. The other route, the east side, has a less severe gradient, but from the summit it is dead-straight for over a mile downhill, which provides an exhilarating descent for cyclists who have struggled up the pass from Llanbedr. Its location also makes it an ideal segment to link up with other climbs in the area, including The Shelf and Horseshoe Pass.
