“When spring came, even the false spring, there were no problems except where to be happiest. The only thing that could spoil a day was people and if you could keep from making engagements, each day had no limits.”

That’s a fun quote from Hemingway. I take it to mean prioritise walks above socialising, now it’s a bit warmer (I reserve the right to be wrong about that) and to get out in the woods and downs, witness the transformation from grey and brown to green, blue and yellow. I say “witness” but it happens suddenly, overnight perhaps, when you’re not looking. Suddenly the air is soft, the countryside hues have changed and spirits have lifted.

We chose the 3.5-mile Knockholt/Chevening North Downs route for late Saturday afternoon and a 4.5-mile stroll on the Greensand Ridge at Hosey for the following morning. On the Hosey route bluebells were two-thirds in bloom and were mixed beautifully with stitchwort and anemone. We heard coal tit, nuthatch, song thrush, chaffinch joining in the merry burble of song from great and blue tits, robins and wrens. A delightful pint of Westerham Brewery’s Light Ale ensued after the walk at Squerry’s Winery.

At Knockholt, along the escarpment, three red kites drifted overhead throughout the walk and a pair of buzzards hung in the air. These raptors love the updraft along the ridge and I think this walk is the most reliable route for seeing them on of all the walks here, though they can pop up on any. Please don’t think me callous but I rather hope the birds of prey feast on pheasants; there are too many of the latter human-introduced birds in these parts and they kill a large number of reptiles and amphibians.

The chalk Knockholt/Chevening walk on the North Downs ridge is separated from the Hosey walk on the Greensand Ridge by the clay Vale of Holmesdale, an east to west valley that runs in parallel to the two lines of hills and which contains the M25 and M20 motorways. Holmesdale clay runs between the chalk and sandstone yet despite the starkly different geology in such a small distance the plants and tree species don’t superficially appear to differ that much – presumably the plants have adjusted to the contrasting soils over the millennia. But there are some differences – there are more likely to be orchids and expanses of grassland on the less densely wooded chalk hills; while on the greensand the woods seem a tad more extensive and are more likely to include stands of pine, which like the sandier soils. I’m no expert so I won’t go on. Bluebells like both; that’s the main thing and this week they are reaching their peak at sites like Meenfield Wood, Scords Wood, and Mariners Hill. Enjoy them, they’ll be gone within about four weeks.
