Great loop around the reservoir, all kinds of gravel.

We visited for the Parkrun, which was cancelled whilst a walkway is fixed (some more weeks, I would expect). You can still access the lake along the disused railway line for part of the way - but not a good surface for running. Then there is a path around the lake with views across the lake and stretches through the woods, lovely, if rather muddy in places following wet weather. In total about 9 km around. Hope to do this again in the Spring with the promise of wild daffodils and perhaps a red squirrel.

Mynydd Bodafon is a small collection of peaks including Yr Arwydd which is the highest point on the island of Anglesey. It lies about 2+1⁄2 miles west of the coastal town of Moelfre and ⅔ of a mile south-west of the hamlet of Brynrefail. The meaning of Bodafon is obscure. You can see the road below that you came in on to give you an idea of the height.

Llyn Cefni Dam During World War II, a water scheme was devised for the town of Llangefni in central Anglesey. It involved water from a local source being pumped to two settling tanks in the Dingle part of the town. From here the water was pumped across the river to a reservoir and water tower, on the site of the present Pennant Estate. These arrangements became redundant with the building of the Cefni Reservoir, which was completed in 1951, but the settling tanks and pumping station survive in Llangefni to this day. The new scheme was designed to supply most of the water needs for the people of Anglesey for the foreseeable future

Llangefni (meaning "church on the River Cefni", Welsh pronunciation: [ɬaŋˈɡɛvni]) population 5,116, making it the second-largest town in the county and the largest on the island. The community includes the village of Rhosmeirch. Wonderful welsh town with all the shop can get busy in summer holidays.

Cors Erddreiniog is beautiful year-round, but the best time for family hikes often depends on what you want to see. Spring and summer (late spring to early autumn) are ideal for spotting wildflowers, including rare orchids, and observing insects like butterflies and dragonflies. Birdwatching is excellent throughout the year, with different species present in summer and winter. Always be prepared for potentially marshy conditions, especially after rain, and consider appropriate footwear.
Given the varied terrain and wetland environment, we recommend packing waterproof footwear, such as walking boots or even Wellington boots for marshier sections. Layers of clothing are advisable, as the weather can change. Don't forget water, snacks, sun protection, and binoculars for wildlife spotting. A map or a fully charged phone with the komoot app is also helpful for navigation.
