Unfenced Existence: Tetney Marshes

Cleethorpes is a lovely, characterful place - if busy with families enjoying their hols at this time of the year. Walking South along the Humber, beyond Cleethorpes, beyond the 'Pleasure' park, past the caravans and the moored yachts, it is possible to walk in peaceful isolation in a unique and desolate landscape: the Tetney Marshes. Wikipedia tells me that the marshes
"cover over 1,500 hectares of coastal mudflats, salt marsh, dunes and saline lagoons on the north Lincolnshire coast, the reserve forms an important part of the Humber Estuary Site of Special Scientific Interest and Special Protection Area, administered by the RSPB as the Tetney Marshes nature reserve, which functions as a grazing marsh and home of lagoon sand shrimps". 
So, it's probably a good thing that there aren't so many human visitors, I guess. Still, I'm moved to share my experience, as I found the walk in such an environment to be remarkable. Here's the 25 mile (there and back) route we took:

The geography of the area is all about movement, due to the ebb and flow of the river at this point in the estuary, and the twists and turns of the trail give the impression of the various landmarks - the wartime forts, Spurn Head lighthouse - themselves shifting position, now ahead, now behind, now left, now right. And that was before visiting the excellent Greyhound Inn at Marshchapel. I took a few pics along the way...

Here is unfenced existence:
Facing the sun, untalkative, out of reach.
