This is in dedication of Aneurin Bevan here is a plaque dedicated in his memory here is the memorial on this stone. Which only was put in place in the late memory of Sir, Aneurin Bevan, who was the actual true sole founder the man who had created the incredible service of our whole nation of the United Kingdom the live-saver service of the NHS - National Health Service. This is a historical site and lots of tourists whom have visited have said solely because they have an interest in the history and the background of the whole nature to the creation of the NHS.

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.
