The bay is on the Anglesey Coastal Path at grid reference and has, with most of the rest of the coast of Anglesey, been designated as an Area of Outstanding Natural Beauty by the UK government. The geological makeup of the area is mostly Devonian Old Red Sandstone, although the north side of Traeth Dulas sees the limestone beds alternating with shale and gritstone. There are unusual levels of zinc and copper in the soil, and a water-table brought in by Afon Goch from the nearby Mynydd Parys (Parys Mountain) mines. However, the level is nowhere near high enough to be of danger to humans or animals. Just two and a half miles from the bay is Mynydd Bodafon, the highest point on the Anglesey mainland, reaching 178 metres above sea level.
