Ystrad Mynach is the principal settlement of the upper Rhymney Valley section of Caerphilly borough, home to Ystrad Mynach College and the Rhymney Valley's main retail corridor. The town sits at a valley widening where the river gradient eases, giving a broader flood plain and a more open feel than the narrow upper valleys; sycamore on the valley sides gives a reliable May flow, and white clover is abundant on the college and leisure-centre grassland. Nelson Bog — a raised mire SSSI to the north of the town — provides a distinctive forage of cross-leaved heath, bog myrtle and purple moor-grass for any colonies on its margins. The Cardiff, Vale and Valleys BKA covers Ystrad Mynach and the surrounding Caerphilly villages.
Collectors handle swarms in the residential streets around the college and the town centre, in the garden plots of the hillside estates above the valley floor, along the Rhymney River corridor and its scrub margins, on the bog-edge bramble and gorse at the Nelson Bog SSSI perimeter, and in chimney pots and eave voids of the older terraces on the roads towards Nelson.

Sycamore is the defining tree across these valleys, blanketing every south-facing slope and delivering a generous May flow almost regardless of colony location. Hawthorn on valley-side hedge lines and blackthorn in scrub above the terraces follows through late spring. White clover persists on allotment gardens, valley-floor parks and the gentler upland grazings from June onward. Bramble is dense on reclaimed colliery tips, forest margins and Sirhowy and Ebbw valley sides; bilberry and ling heather on the Gelligaer, Mynydd Islwyn and Mynydd Llangynidr plateaux provide a useful late-August supplement for hives on the valley rim. Alder and willow along the Rhymney, Sirhowy and Ebbw corridors contribute early pollen; meadowsweet and purple loosestrife on wetter valley-floor ground extend the late-summer flow. Ivy on old stone chapel walls and valley-side garden walls closes the year.
