The estuary of the River Erme, Devon

This photo, taken in 1997 as far as I can recall, shows the estuary of the River Erme in Cornwall.

Other estuaries on the South West Coastal Path have a bridge or a ferry, but you have to wade the Erme at low tide.

I arrived a bit before then, but took local advice and crossed a little downstream from where the guidebook said. I had no problems.
