Enjoy the walk up from Clifford Mesne, and then taken in the expansive views. Don't miss the copse at the top, planted to commemorate Queen Victoria's Golden Jubilee.

The Wye was voted the nation’s favourite river in 2010. It starts not far from my home town in Brecon in mid-Wales and trundles south for some 150 miles before meeting the Severn. I have forgotten how many times I have cycled it, run it and kayaked it. Simply my favourite place on earth!

Doable on an MTB, but not by me without an electric motor.

The fourth-longest river in the UK, the Wye stretches 155 miles (250 km) from its source on Plynlimon in the Cambrian mountains to the Severn estuary. For much of its length, the Wye marks the border between England and Wales, with the lower section being designated an AONB. The Wye is important for nature conservation and recreation, but, particularly in recent years, is severely affected by pollution.

This pretty, wooded area with its network of small caves - the result of former quarrying - is a nature reserve with a rich variety of flora and fauna. Horseshoe bats and rare invertebrates such as the cave spider and hibernating herald moths make their homes within the caves.

Puzzlewood (grid reference SO578092) is an ancient woodland site and tourist attraction, near Coleford in the Forest of Dean, Gloucestershire, England. The site, covering 14 acres (5.7 ha), shows evidence of open-cast iron ore mining dating from the Roman period, and possibly earlier. Over a mile of pathways were laid down in the early 19th century to provide access to the woods, and provide picturesque walks. The area contains strange rock formations, secret caves and ancient trees, with a confusing maze of paths. The site is listed as a regionally important geological site in the 'Forest of Dean Local Plan Review'. The geological features on show at Puzzlewood are known as scowles. Scowles originated through the erosion of natural cave systems formed in the Carboniferous Limestone many millions of years ago. Uplift and erosion caused the cave system to become exposed at the surface. This was then exploited by Iron Age settlers through to Roman times for the extraction of iron ore. It is usually impossible to date open-cast extraction precisely, although ores with a chemical signature consistent with those from the Forest of Dean were certainly used to make tools and weapons in the late prehistoric period. Over 3,000 Roman-era coins were found by workers in 1848. The coins were stored in three earthenware jars in a cavity in the rock formations. The origin of the coins is unknown. Puzzlewood has been used as a filming location for both film and television in recent years. Notable examples include: Films Harry Potter and the Deathly Hallows – Part 1 (2010) Jack the Giant Slayer (2013) Star Wars: The Force Awakens (2015) The Huntsman: Winter's War (2016) A Midsummer Night's Dream (2016) The Secret Garden (2020) Television Doctor Who (2005-present) Merlin (2008-2012) Wizards vs Aliens (2012-2014) Tree Fu Tom (2012-2016) Atlantis (2013-2015) Da Vinci's Demons (2013-2015) Hidden Kingdoms (2014) The Dark Crystal: Age of Resistance (2019) Cursed (2020-present)

I was silly and forgot my tortch before first light don't do the same!

caves wasn't big and was a steep incline to get to them. i would miss them out next time

King Arthur's Cave is a limestone cavern at the foot of a low cliff at the north-western end of Lord's Wood, near Symonds Yat. The cave entrance lies about 285 feet (87 m) above the River Wye. It has a double interconnected entrance and two main chambers. Protected as a nature reserve under the Herefordshire Nature Trust, there is evidence that the cave was occupied by man during the Upper Palaeolithic era. Flint tools and woolly mammoth bones have been unearthed within and around the caves.

Distinct and visible for miles around, May Hill has a little hat of trees on top. A Marilyn, it lies just north of the Forest of Dean in Gloucestershire and two named trails cross it: the Gloucestershire Way and the Wysis Way. Enjoy the far-reaching views from the summit towards the Welsh border and over the River Severn.

A nice little hike in the English countryside to take in a May Hill. At 295m it is a UK listed Marilyn so one less to do.

This remarkable series of dams (at least 60) occurs over nearly half a mile of Slade Brook. They completely dam the stream, which is from 3 to 30 ft wide, and range from about 1 to 18 inches in height, with an average of about a foot. Such dams are formed when spring water, near-saturated in lime, runs over obstructions in the stream bed, when loss of dissolved carbon dioxide results in deposition of travertine (a porous, friable type of limestone). Development of dams may well have been initiated by water running over accumulations of twigs and branches across the stream. The dams are colonised by various species of moss and algae, which become encrusted by travertine as the dams build up, and they have considerable conservation value. Most of the water in the stream is discharged from a large spring, which emerges from the Carboniferous Limestone bedrock near the head of the valley. The Slade Brook dams are possibly the best example of such structures in the country. On no account should they be touched, as they are easily damaged.

Highest point in the area (Trig point) Very good views. Benches in the close to sit down and enjoy your lunch. Plenty of trails to follow from here
