Mynydd Mawr is a mountain in Snowdonia, in the county of Gwynedd, North Wales. Its elevation reaches 698 m ( 2290 feet) and is located about 7 km (4.3 mi) west of Snowdon, overlooking Llyn Cwellyn. A popular climb begins from Rhyd Ddu. On its western slopes are found the remains of ancient settlements and filed systems. Seen from the north is frequently thought to resemble an elephant lying down, and because of this the summit is often named "Yr Eliffant" ( "The Elephant").
