Mynydd Mawr (Welsh for big mountain) is a mountain in Snowdonia, North Wales, situated approximately 7 km (4.3 mi) west of Snowdon itself, overlooking Llyn Cwellyn and being the northern outlier of the Moel Hebog group. A popular ascent starts from Rhyd Ddu. On its western flank are the remains of ancient settlements and field systems. The profile of Mynydd Mawr from the north is often thought to resemble an elephant lying down, and consequently the mountain is often colloquially also called "Yr Eliffant" ('The Elephant'), or "Elephant Mountain" to non-Welsh speakers.
