Glyn Y Mul Farm, known as the "Lone Wolf" campsite, is a privately owned woodland site located just outside Aberdulais in South Wales, where the River Dulais runs through approximately 18–20 acres of natural deciduous woodland.

Operating since 1999, it caters to a small number of campers at a time, with pitches available in a top field near basic facilities or deeper in the woods for a more immersive experience.

The ethos here is firmly back-to-basics and focused on quiet enjoyment of the countryside. Vehicles are not permitted into the woodland; campers park near the gate and walk in. Many visitors opt for a hammock or bivvy rather than a traditional tent.

This is not a site for those seeking entertainment or on-site amenities — it suits those looking for genuine seclusion and simplicity in a natural woodland setting.
