This walk begins with a cup of tea at Flatford Mill, a site steeped in history and immortalized by John Constable's paintings. Standing before the mill, now a Field Studies Centre, its weathered timbers stand sentinel over the placid River Stour, its waters reflecting the dappled sunlight filtering through overhanging willows. The rich air is scented with damp earth and wildflowers.

My path meanders through the plains of Dedham Vale, an Area of Outstanding Natural Beauty that seems to exist in a timeless bubble. Ancient hedgerows line parts of the trail, their gnarled branches home to a chorus of songbirds. Blackbirds and thrushes flit between the thorny embrace of blackberry bushes, while the distinctive "see-saw" call of the great tit echoes nearby. I am reminded of the old folk song, Pleasant and Delightful:

It was pleasant and delightful one midsummer’s morn,

When the fields and the meadows were buried in corn,

And the blackbirds and thrushes sang on every green tree,

And the larks they sang melodious at the dawn of the day.

Meadows unfurl on either side of me, a patchwork of emerald and gold. This late summer day finds these fields a riot of colour – buttercups, red clover, and purple knapweed creating a living canvas that sways gently in the breeze.

The path dips and rises with the gentle contours of the land, each crest revealing to me new vistas of the quintessential English countryside. Grazing cattle dot the landscape, their presence a living link to centuries of agricultural tradition. Their presence made my walking partner slightly nervous, convinced that one of the cows would chase after us – this did not happen, thankfully.

The river is never far from my side, its presence marked by a line of tall trees. I had hoped for the elusive flash of iridescent blue from a kingfisher darting past, but alas. In the shallows, I spot water voles leaving rippled V-shaped wakes as they swim between the reeds, while dragonflies perform aerial acrobatics above the surface.

As I near Manningtree, I notice the landscape gradually shifting. The river widens, and I see the first hints of the estuary's brackish influence in the vegetation. Sea lavender and glasswort add splashes of purple and green to the mudflats exposed at low tide, where I watch wading birds probe for a crustacean lunch.

Finally, Manningtree comes into view, its post-industrial quayside a welcome sight after my day's exertions. I find a seat at The Crown pub by the river and order a cold glass of local pale ale. As I sip the crisp, hoppy notes - the perfect complement to the salty tang in the air – the River Stour stretches wide before me, its waters now decidedly tidal.

Sailing dinghies from Stour Sailing Club tack back and forth, their white sails billowing in the freshening breeze. Across the water, the Suffolk shore presents a mirror image of the Essex landscape I've traversed – a reminder of the shared heritage of this borderland between two ancient counties.

As the sun dips lower, casting long shadows and painting the sky in hues of pink and gold, I reflect on my day's journey. From the timeless beauty of Flatford Mill to this bustling riverport. Draining my glass, I realised that the essence of this landscape – one which has inspired artists and nature lovers for centuries – remains unchanged despite the mercurial passage of time. Long may that continue.
