"Castell Cawr, or Tan-y-Gopa as it is known locally, is a heavily forested hill above the town of Abergele in North Wales. On it is found the Iron Age hill fort of Castell Cawr, which overlooks the River Clwyd. Rare lesser horseshoe bats inhabit caves on the hill. The woods are owned by the Woodland Trust. The hill rises to 189 m (620 ft) above sea level, with extensive views to Snowdonia and the Clwydian Range. Thomas Pennant visited the area in the 18th century, and noted the existence of the hillfort. In 1860, James Halliwell-Phillipps wrote that the outline of the hillfort was obscured by vegetation, and identified the workings of a Roman lead mine on the hillside. The Welsh knew these excavations by the name "Ffos-y-bleiddiaid" ("Ditch of the Wolves")" Source: https://en.m.wikipedia.org/wiki/Castell_Cawr

The tranquillity of Bryn Euryn hill, 365 feet above sea level, belies a dramatic yet little known past. Iron and Dark Age strongholds, the medieval castle of a notable Welshman and a later fortified mansion have all been built here, and a Roman expeditionary force disappeared nearby. Bryn Euryn rises above the North Wales town of Colwyn Bay, dominating the old Welsh kingdom of Rhos. The ancient fortresses stood on its summit and the ruins of the fortified mansion are on its seaward slope. Historical records hint that Ednyfed had a castle here but where was it? The site commands extensive views of the Conwy Valley and coast, and was once the location of a hillfort, which was initially excavated in the autumn of 1997 for the Gwynedd Archaeological Trust. The excavations revealed a "massive, well-built" wall formed from quarried limestone, believed to have once been 3 m (9.8 ft) high and to have been fronted by 3.5 m (11 ft) of rubble. There were no archaeological discoveries permitting a certain identification, but the pre-Norman layout led David Longley, the study's director, to connect it with the early-6th century king of Rhos Cynlas the Red on the basis of the "Bear Den" (Latin: receptaculi ursi) mentioned in Gildas's passage on him and the surviving local name of the area as Dinerth, "Fort Bear" The hilltop was used again in World War II first as an observation post by the Home Guard; it was then used by the RAF as one of the first radar posts used to detect German bombers heading to Liverpool.[

The Little Orme (Welsh: Rhiwledyn, also known as Trwyn y Fuwch, Trwyn y Gogarth and Y Gogarth Fach) is 141 metres (463 ft) in height, and is a HuMP (having a minimum Hundred Metre Prominence). It is one of two headlands situated at either end of Llandudno Bay, in Conwy County Borough, Wales. The other, larger, headland is the Great Orme. It has two summits, the higher with a trig point. The cliffs are a popular challenge for highly experienced rock climbers. The Coast Guard Rescue Unit use the Little Orme for training. Otherwise, it is a popular sightseeing location and walking/hiking site. The Little Orme was inhabited during the Mesolithic and Neolithic eras, notably the Pant y Wennol cave. A small hoard of Iron Age Celtic metalwork was found in a cave on the Little Orme. The medieval chapel of Blessed Mary of Penrhyn, abandoned in 1930 and now in ruins, is at the foot of the Little Orme in the grounds of Penrhyn Hall at Penrhyn Bay. On 14 April 1587, printing material for Catholic literature was found in a cave on the Little Orme, where it had been used by the recusant Robert Pugh (squire of Penrhyn Hall) and his Chaplain Father William Davies to print Y Drych Cristianogawl (The Christian Mirror), the first book to be printed in Wales. They had taken refuge there during the persecution of Catholics instigated by Queen Elizabeth I in May 1586. The Royal Artillery coastal gunnery school, 198 battery, was posted to Little Orme during the Second World War. Target practice was undertaken from the headland to anchored boats, and unspent ammunition and unexploded shells may still be encountered offshore. Gun emplacements and ancillary buildings were in situ until at least the early 1960s, but the site has since been 'landscaped'.

Trwyn Y Fuwch has a very large rock formation of hills, these stick out considerably as you ride along the flat promenade. When you get close to then you realise the size
