Nant Milgatw Waterfall located near Trefil Tredegar Gwent. It’s Small waterfall on the back of the stream Nant Milgatw. Normally not this much water coming over the top like I’d experienced today. Hands down this has to be the stinkiest waterfall I’ve ever seen, water was filthy like brown sludge not what I expected to see. There is many of great walking routes that all can use the same start point as here or along the Trefil Rd, as I’ve gone way beyond this point previously and it’s definitely worth the explore there are so many other routes that can lead you up onto the surrounding mountainsides above. Including the incredible Chartists Cave. The Appropriate footwear is definitely required here as terrain can vary depending on the weather conditions route and height.
