July 12, 2026, Neath Canal Aqueduct Over the River Neath at Ynysarwed

For some reason I thought the one on the Mon & Brec Canal was a one off, obviously there are more. There's something cool about a 'bridge' to take a canal over a river.

This is really cool. I wish there were more like this on other bits of the canal network.

Not a path for the road bike, unless you like a bit of wrist punishment. Suits anything with a wider tyre, 35c and bigger I would say.

Always a nice ride across this section. Great views, but can be mucky in the winter.

Always a good place to stop for refreshments. It’s a popular pub and can be busy at times.
