Loe Bar was originally the mouth of the River Cober which led to a harbor at Helston. However, by the 13th century the bar had cut Helston off from the sea and formed the lake. Loe Bar consists largely of chert deposits, although it is not certain where this comes from as the nearest source is more than 200 kilometers away. There is also a reasonable amount of sand.

It might not look like it, but there is a bridleway here which crosses the sand bank, Loe Bar. The lake, the Loe, is the largest freshwater lake in Cornwall and the coastal bar separates it from the sea. It was once the mouth of the River Cober. Some say it was formed when two local giants had an argument and one of them dropped a bag of sand here as he was being attacked by the other throwing rocks at him, one of which being St Michael's Mount. No wonder he was keen to get away!
