PLENTY of people have crossed over the Pontcysyllte Aqueduct over the years but now snakes can be added to the list.

Twitter user @HannahWrex captured the slithery swimmer as it made its way across the World Heritage site on Monday afternoon, and was grateful she wasn't in her kayak at the time.

She wrote: "Also today I raced a snake across the @Pontcysyllte aqueduct from @TrevorBasin! First time seeing one of these in the canal, quite glad I wasn't in a kayak!"

It is not clear what type of snake can be seen in the video, but what is clear, is that it clearly won the race to the other side!
