8pm, Channel 4
Part-documentary, part-promotional video for the Welsh tourist board, this visually spectacular, somewhat effusive new series posits Wales as God’s own country. Essentially, it’s an adoring deep-dive into the beautiful landscapes of Snowdonia, the fecund glory of the Pembrokeshire coast and the picturesque Vale of Ffestiniog. We meet a father and daughter team of steam train enthusiasts, a lobster fisherman and, perhaps inevitably, a sheep farmer. Plenty of ideas if you’re considering a late summer holiday. Phil Harrison
