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.

Llyn Brenig is a reservoir located on Denbigh Moors in North Wales. The artificial lake, which was constructed between 1973 and 1976, was created by building an embankment dam across the Afon Brenig valley. It lies at 1,200 ft above sea level on the border between the counties of Conwy and Denbighshire.

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.

Llyn Brenig is located at the heart of the Mynydd Hiraethog and is a good base for outdoor activities, including walking, cycling, fishing and sailing. It is a great spot for a break off the bike and the area is surrounded by a network of footpaths and a number of way marked trails suitable for biking and walking, including the Brenig Trail. The Visitor Centre provides toilet facilities and a cafe.
