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.

Almost like walking on the moon - but then in all shades of yellow and orange.

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.

Mynydd Parys...❤️ 🏴 "Copper Kingdom" 👌🏴 Absolutely amazing place to explore, numerous times I've visited here and each time I have I've felt the presence of my late dad... Honestly it blew my mind being here, not only did the colours give you a feel of walking on Mars.. Even though mars has never been walked upon yet. To think of the history of this incredible adventurous open cast pit holds, still. Known as 'copper kingdom' Parys Mountain is one of Anglesey’s must-visit locations! Truly amazing walking landscapes of the ancient copper mine at Parys Mountain. A sight that is really not to be missed is the spectacular Great Opencast, shaped by miners using nothing more than picks, shovels and gunpowder! There is a level walk around the top of the Great Opencast and a viewing area with a stunning panorama that shows off the excavation’s amazing colours, like I said felt like Mars! It became known as the ‘Copper Kingdom’ The mine owner, Thomas Williams became known as the ‘Copper King’. Even today, there is thought to be a reserve of about 6 million tonnes beneath the old mine workings. Must say in all the times I've visited here I've never seen the place so busy.. Plenty of space to park if not busy and for free.. Highly recommended ❤️
