Enter this enchanting ancient beech wood to find a mossy gorge, waterfalls and an old stone bridge over the Anghof river. There is a vast lake, from the slate-quarrying era, connecting to a fascinating man-made stream ravine (fun on an inner tube).
N from Haverfordwest on A40, just N of Wolf’s Castle, turn R into cul-de-sac Quarry Lane (SA62 5ND, park here or layby off A40 just beyond). Follow footpath at end and bear R at junction down towards stream. 300m upstream, beyond activity camp, is the lake. 10 mins, 51.9080, -4.9675
