The centre point of Wales is dependent on whether only the mainland is used for calculation or outlying islands as well.

One centre point is calculated to be near Cwmystwyth, Devil's Bridge, Ceredigion (; )

Elevation extremes

Wales: Snowdon (Yr Wyddfa) in Snowdonia (Eryri) - 1,085 m (3,560 ft)

Many points are on, or near sea level, but due to high rainfall, there are no natural dry pieces of land below sea level - see rivers and lakes below.

Rivers and lakes

The largest natural lake in Wales is Llyn Tegid (Bala Lake). Llangorse Lake is second largest by area.

The River Usk is the longest river to flow wholly within Wales. The table below lists Wales' longest rivers including (in italics) those only partly in Wales.
