A Hidden Gem: The Welland Viaduct | The UK’s Longest Masonry Viaduct

There’s something really special about spontaneous after-nursery walks in Rutland and the Welland Valley. No plan, no pressure, just fresh air, muddy boots, and a toddler fully committed to exploring absolutely everything in sight.

One of our go-to family walks is along the River Welland beneath the iconic Welland Viaduct, right on the Rutland–Northamptonshire border. It’s an easy, relaxed circular-style wander with wide open space, riverside views, wildlife spotting, and if you’re lucky, the unmistakable sound of a train crossing above your head.

For little ones who love trains, nature, puddles, and freedom to roam, this spot is spot on.

The real highlight is always standing directly underneath the viaduct. With Stanley, it quickly turns into a game of echoing voices, laughter bouncing off the arches, and seeing just how loud a toddler can possibly shout.

The Welland Viaduct (also known locally as Harringworth Viaduct or Seaton Viaduct, depending on which side of the valley you’re from) is an extraordinary piece of British engineering. Completed in 1878 and designed by William Henry Barlow, it stretches across the valley with 82 arches and remains the longest masonry viaduct in the UK. Built from millions of bricks, it still carries the railway line today and dominates the landscape in the most spectacular way.

What always amazes me is how many people locally still don’t know it’s there. This enormous Victorian structure sits quietly in the Welland Valley, often hidden just beyond a hill or tucked away behind roads people have driven down countless times. You can be minutes away and completely unaware it exists.

I grew up in the village of Harringworth, with the viaduct as the view from my bedroom window. It’s always been my calm place, my favourite view, my reset button, and somewhere I still go when I need a bit of headspace.

The walk itself is simple, family-friendly, and perfect for little legs.

You can access the footpaths from either:

• Seaton Road (NN17 3AF) via the village hall

• Gretton Road (NN17 3AD)

Follow the public footpaths through the kissing gates towards the viaduct, then wander underneath the arches and along the River Welland at your own pace.

If you’re looking for a peaceful family walk, a toddler-friendly adventure near Rutland, or one of the most impressive hidden landmarks in the UK, this one is well worth discovering.

Don’t forget, while you're there, visit Harringworth Café. The café is a pop-up in the village church, open for the summer months from April through to the end of August at St John’s Church (NN17 3AF). Running every Saturday from 10:30 am to 12:00 pm, it’s a lovely community café serving coffee, homemade cakes, sausage rolls and more, all run by local volunteers. All proceeds go directly to the Harringworth Appeals Fund, supporting village projects and community initiatives.
