Gainford Spa and the Sulphur Spring by the River Tees
Hidden beside the River Tees near Gainford, this unusual sulphur spring has been drawing curiosity for nearly two centuries.
Today it feels peaceful and almost forgotten. A short riverside path leads down to a small stone fountain where cold mineral water still flows naturally into the river below. The smell is unmistakable. Sharp sulphur, often compared to rotten eggs, drifting through the air before quickly fading again beside the water.
But during the Victorian era, people travelled here on purpose.
Visitors arrived by railway to “take the waters”, believing the sulphur-rich spring could help with everything from skin complaints to digestive problems. Guesthouses appeared above the station, the village became known for its spa water, and for a time Gainford joined the growing list of spa destinations across Britain.
Today the crowds have long disappeared, but the spring still flows quietly beside the Tees, carrying with it one of the most unusual and overlooked pieces of Teesdale history.

Where is Gainford Spa?
Gainford Spa sits beside the River Tees just outside the village of Gainford, between Darlington and Barnard Castle.
If you are travelling along the A67 towards Barnard Castle from Gainford, you will see a small roadside layby beside an information board near the edge of the village. From here, a short path drops down through the trees towards the river.
Within a couple of minutes you reach the spa itself, tucked quietly into the riverside stonework beside the Tees.
Although close to the road, it feels surprisingly hidden once you reach the water.
The Discovery of Gainford Spa
The spring was discovered in 1834 when a borehole was sunk beside the River Tees.
Some accounts suggest the original drilling may have been connected to searches for coal, but instead of fuel, workers uncovered an artesian spring of naturally rising sulphur-rich mineral water.
At first the site was simply known as the Borehole Well.
But during the nineteenth century, mineral springs were attracting growing attention across Britain. Water containing sulphur, iron and other minerals was widely believed to have restorative properties, and towns with natural springs often reinvented themselves as spa destinations.
Gainford quickly followed the same path.
Why Gainford Became a Victorian Spa
By the Victorian era, “taking the waters” had become hugely fashionable.
People travelled across Britain to drink, bathe in, or simply experience mineral-rich spring water believed to support health and wellbeing. Sulphur springs were especially associated with digestive complaints, skin conditions and general ill health, and Gainford Spa soon developed a local reputation for its unusual water.
At the time, people believed the spring could help with problems including indigestion, constipation, acidity, liver complaints and chronic skin conditions. Whether these claims truly worked was another matter, but many visitors placed genuine trust in the restorative power of mineral waters.
The spring’s strong sulphur smell quickly became part of its identity. Visitors often compared it to rotten eggs, caused by naturally dissolved sulphur gases rising through the water itself.
Despite the smell, people still travelled here to drink it.
The Railway and the Rise of Visitors
Gainford Spa became far easier to reach when Gainford railway station opened in 1856 on the Darlington to Barnard Castle line.
The railway transformed travel through Teesdale and helped bring visitors into the village during the height of Victorian spa culture.
Historical accounts describe guesthouses and boarding accommodation appearing on the higher ground above the station for visitors staying to experience the spa water.
Gainford never developed into a grand resort like Harrogate or Bath, but for a period it became a recognised local spa destination within the Tees Valley, alongside places such as Croft Spa and Dinsdale Spa.
The village briefly became part of a wider Victorian fascination with natural health, mineral water and countryside retreats.
Bringing the Spa Water into the Village
The spring became important enough locally that discussions were held about making the water more accessible within Gainford itself.
An 1877 record relating to William Simpson references a proposal concerning the bringing of water from Gainford Spa onto the village green.
Even though the plan never transformed Gainford into a major spa town, it shows just how seriously the spring was once viewed by the local community.
For a time, people genuinely believed the spa water could help shape the future of the village.
Decline of the Spa
As the twentieth century approached, interest in spa waters slowly began to fade.
Medical understanding was changing, and many of the old beliefs surrounding mineral springs gradually lost popularity. The First World War also changed travel habits and tourism across Britain.
The last known spa boarding house connected with Gainford Spa closed in 1910.
After that, organised visits faded away and the spring quietly slipped back into the landscape beside the River Tees.
Damage and Restoration
Although the spring survived, the original Victorian stonework suffered damage over the years through neglect, flooding and vandalism.
By the late twentieth century parts of the old structure had been lost to the river.
In 2000, divers recovered sections of the original stonework from the River Tees, helping preserve part of the spa’s earlier history.
Then in 2002, with support from local villagers and restoration efforts, the spa spout was carefully recreated and restored.
What visitors see today is therefore not an untouched Victorian structure, but a thoughtful restoration that helps preserve an unusual and important part of Gainford’s history.
What the Water is Like Today
The spring still flows naturally all year round.
At the source the water is cold, clear and strongly sulphurous. The smell is caused by naturally dissolved gases rising from the mineral water, although it fades quickly once exposed to the open air.
Local tradition says the water makes an excellent cup of tea once boiled, though opinions on that tend to vary quite a lot.
Modern medicine no longer supports the old Victorian healing claims once associated with spa waters, but the spring still offers something fascinating. It provides a direct link to a time when people looked to nature itself for health, comfort and recovery.
Visiting Gainford Spa Today
Gainford Spa is not a large tourist attraction and there are no visitor facilities beside the spring itself.
That is part of what makes it special.
There are no ticket booths, cafés or gift shops here. Just a short riverside path, flowing mineral water and the quiet sound of the River Tees nearby.
A simple stone bench beside the spring gives visitors a place to stop and take in the setting.
If you visit, please help keep the area peaceful and leave it exactly as you found it.
A Moment of Calm by the River
Gainford Spa was never really about grand buildings or famous landmarks.
It was about hope.
People once travelled here believing the water might help them feel better, healthier or calmer. Nearly two hundred years later, the spring still flows beside the Tees exactly as it always has.
Today it offers something much simpler.
A quiet hidden place beside the river, and a small reminder that even the strangest corners of Teesdale can still carry stories worth slowing down for.
A moment of calm by the river
Gainford Spa was never about grand buildings or bold promises.
It was about hope, belief, and the idea that nature might offer something restorative.
Today, it offers something simpler. A quiet place beside the river, and a connection to the people who once stood here, holding a cup, trusting the water, and believing.
Sometimes, that story is enough.
