The South West Coast Path follows the
tidal road at the Avon, with a high tide detour over the adjacent hill. When I was walking it I arrived just as the tide was coming in, but I could see the low point that floods and decided I had time to get across rather than climb the hill. Then half a mile up the road I came to another low point which was submerged by now, so I turned back and ran as fast as I could with walking boots and a 30lb rucsac, splashing through the now submerged section that I'd just come along. When I got to the pub in Aveton Gifford the barman said "Oh, you'd have been alright, that second bit is the last one".
When I was back there on the bike ~10 years later the tide was out.
The
Strood at Mersea floods on spring tides, but I've only ever seen it covered once. I arrived just as the tide was turning, and had a wait of an hour before I could ride across dry on the path. By that time the cars had already been driving through a few inches on the road for several minutes, but I didn't want my rims full of salt water. AFAIK, at one time the Peldon Rose used to have a special concession to remain open out of hours when the Strood was covered as a refuge for travellers.
I followed road signs to
Tarr Steps at a time when I'd never seen them before, but when I saw what was there I wasn't about to drive through that, so I turned round.
In Whitby, as l type
I might head back over the ‘moor road’ from Egton Bridge, to see what the fords are like en-route to Pickering
I remember wrestling the bike over the narrow bridge at Grosmont ford, it wasn't particularly full, but it looked very slippery.
