LOCALS are raging at the amount of human waste found at sites on the popular NC500 route.

In a post on the NC500 The Dirty Truth Facebook group, one person highlighted a popular lay-by on a western part of the route.

“The level of human waste was staggering with tissue scattered everywhere. The smell was awful,” he said.

Another post reacted with anger after finding chemical toilet waste dumped along the side of the main road by Dunnet Bay in Caithness.

“Be careful when walking your dogs at Dunnet/Castletown beach as someone has emptied their chemical toilet. Also on main road. Disgusting,” they said.

We have previously reported how tourists on the popular route have dumped toilet waste, including near a cemetery in Sutherland despite toilets being just one mile away.

One local said, in response: “Saying that most campervanners obey the law is all very well, but there are in excess of 200,000 campervans visiting the NC500 every year.

"If even as low as 1% of them empty their waste in this manner, that's 2000 waste cassettes being emptied. Divide that by the 500 miles of the NC500 and that's four waste cassettes for every mile.

"That's a pretty conservative estimate, and still utterly unacceptable and causing irreversible pollution to the environment. Sadly, I suspect the figure is higher than this."
