The top of the Mynd is a pretty featureless, flattish expanse of moorland - pretty dull this time of year. I find the colours most uninspiring - dull green grass, dark heather and acres of orange dead bracken. Most photographic interest lies in the deep valleys (locally known as 'batches') that penetrate its eastern flanks. Carding Mill Valley is the most popular, the most populated and probably the most picturesque. The waterfall at Lightspout Hollow, part way up Carding Mill Valley, is pretty small so best visited after substantial rainfall.
Ashes Hollow is another batch, starting from the village of Little Stretton, a couple of miles south of Church Stretton. Quieter than Cardingmill but just as picturesque in my view.
Another option for piccies is from the top, looking down. The ridges that separate the eastern batches offer good vantage points both into the batches themselves and across to the neighbouring Stretton Hills. Personally, it's amongst these neighbouring hills that I find the most photographic interest - particularly the area around Caer Caradoc and Hope Bowdler hills.
Now Long Mynd in the summer is a different proposition entirely. The green grass is more lush, the skies are blue and the acres of moorland are ablaze with vibrant purple heather. Well worth a visit.
