Did You Know?
- •The name is derived from the Welsh 'Cam' (meaning crooked or bent) and 'Allt' (a steep hillside or wooded slope), likely describing the irregular, undulating profile of the hill's western flanks.
- •From the summit, walkers are rewarded with a specific view of the Broad Water—a salt-marsh lagoon near Tywyn—and the long, sweeping curve of the Dyfi Estuary as it meets the Irish Sea.
- •Despite its modest elevation, the hill is classified as a Marilyn because its drop on all sides exceeds 150 metres, making it a more significant topographical landmark than many higher peaks nearby.
- •At 288.5 metres, the summit is technically 11.5 metres short of 'mountain' status, a distinction your knees may choose to ignore while navigating its steep, trackless western approach.
