Aber Falls (known in Welsh as Rhaeadr Fawr, meaning 'big waterfall') is a stunning waterfall located in the foothills of the Carneddau range, about 3 km south of the village of Abergwyngregyn in Gwynedd, North Wales. It's a highly popular tourist destination within Snowdonia National Park. Beauty: The falls are beautiful in all seasons, but are particularly spectacular after heavy rain, especially in autumn and winter, when the water flow is at its most powerful. Plunge Pool: There's a shallow rocky plunge pool at the base of the falls, where some brave visitors even take a dip (though the water is very cold!). Rhaeadr Bach: A short distance to the west, there's a second, smaller waterfall called Rhaeadr Fach (or Rhaeadr-bach).

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.

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.
