If you're in the area, be sure to plan at least an hour. Parking is free. It feels like you're on another planet. The trails are very easy, you can visit the ruins of the windmill, and it's simply wonderful. Highly recommended, even with a dog.

On the longest day of the year, sunlight flows into the passageway of this Neolithic burial grounds. Bryn Celli Ddu Burial Chamber is one of Anglesey’s most famous prehistoric landmarks, Bryn Celli Ddu (the ‘Mound in the Dark Grove’ in English) is actually two sites in one. In the early Neolithic (New Stone Age) period, a henge (bank and ditch) enclosing a circle of stones was built here, to be replaced later by a chambered tomb beneath a mound measuring up to 85ft/26m in diameter. Inside, a long, narrow passage leads to an octagonal chamber 8 feet/2.4m across, where artefacts such as human bones, arrowheads, and carved stones have been found.

Absolutely amazing place. Imagine flying to Mars and going for a walk - this is what you would imagine to find there! The colours on the rocks and the general feel and scenery is crazy cool.

Large sandy bay surrounded by dunes. On the north side there are large, striking limestone cliffs of Castell Mawr - certainly geologically interesting, looks like climbers could have fun here... The beach itself is a really large (!) sandy bay, very popular in summer but largely deserted out of season. You can sometimes see kitesurfers and windsurfers here. There is parking behind the dunes and there is a small beach café and shop.

A small but tough and technical climb, beware of sharp rocks on the left hand side when descending

The Dingle Local Nature Reserve is a 10 hectare (25 acre) wooded valley rich in wildlife and history. It is bisected by the river Cefni, which comes from the Welsh word "cafn" meaning trough or hollow. The Dingle is a steep sided gorge formed by glacial meltwater during the last ice age hence one of its Welsh names Nant y Dilyw - Valley of the Deluge. Another name for the Dingle is Nant y Pandy - Brook of the Fulling Mill. This refers to the old wool processing plant situated upstream. Much of the reserve is ancient woodland which led to it being known as the Dingle as early as the 1830s. Dingle literally means steep wooded valley.

Copper has been mined here since the bronze age with recent archaeological digs finding evidence of 4000-year-old mining activity. It's a huge open cast copper mine created entirely by people with spades, pickaxes and dynamite. It's rise in the late 1780's to early 1800's dominated the worlds copper industry, contributing to the demise of the Cornish copper mines. Today it's a scared landscape with only a few plants coping with the copper polluted soil and very few animals. It does create an amazing landscape though, almost alien. Interestingly there is still about 6.5 million tonnes of copper underground which may lead to the mining re-starting in the future.
