In this first episode Iolo is exploring busy Bute Park right in the heart of Cardiff. He has a close encounter with a green woodpecker, finds that it's the best place in Wales to see jays and discovers that it's not only dippers and salmon that can be found along the river Taff when he goes in search of evidence of otters.

In this second episode, Iolo is exploring ancient Dinefwr Park in the beautiful Carmarthen countryside near Llandeilo. He tracks down rarely seen lesser spotted woodpeckers, uncovers the wealth of wildlife found in Dinefwr's special ancient trees and gets up close to brown long eared bats and badgers.

In this third episode, Iolo is exploring an old slate mining family's estate in the Snowdonia National Park. He gets up close and personal with a grass snake, uncovers a rarely seen mammal in the garden and, with help from local experts, uncovers the varied wildlife found in the wild woodlands surrounding the house.
