There’s something wonderfully captivating about travelling through the Tamar Valley by train. This is a landscape where nature and industry sit side by side—where peaceful riverbanks, wooded hillsides, and quiet villages exist alongside the traces of a once-thriving mining landscape. Forming part of the Cornwall and West Devon Mining Landscape World Heritage Site and Tamar Valley National Landscape, the valley invites visitors to explore its unique blend of tranquillity and industrial heritage.
The Tamar Valley Line, which runs from Plymouth to Gunnislake, offers one of the most scenic railway journeys in the South West. Whether you choose to continue to the very end of the line at Gunnislake or step off at Calstock to discover its riverside charm, this journey offers layers of history, nature, and gentle adventure.
Leaving Plymouth: Entering a Rural, Historic Landscape
As the train pulls away from Plymouth, the cityscape fades into a peaceful panorama. The river comes into view, creeks open out to either side, and the scenery grows more rural with every passing minute. But beneath this calm exterior lies a former industrial powerhouse—this valley once thrummed with mining activity, transport links, and river trade.
Your journey is not simply a train journey; it’s a route through a living tapestry of the past.
Crossing the Iconic Calstock Viaduct
One of the journey’s highlights comes as the train glides onto the Calstock Viaduct, a breathtaking 12-arched structure that soars high above the River Tamar. From here, the views stretch across a landscape shaped by both natural beauty and industrial endeavour.
Beneath the viaduct sits the riverside village of Calstock, its cottages clustered along the water’s edge. Today it’s a peaceful settlement, but in the 19th century it was alive with activity as one of the busiest ports on the Tamar, with barges transporting minerals, timber, coal, and goods linking local mines to the world beyond.
You can stay aboard the train as it leaves Calstock and climbs deeper into the Tamar Valley. This final stretch to Gunnislake rewards you with sweeping views of wooded valleys, patchwork fields, and traces of old mining works.
Step off the train at Calstock to explore one of the most charming riverside villages in the South West. It’s an ideal base for those who enjoy walking, riverside scenery, heritage landscapes, and the slower pace of rural life.
Calstock: Once a Busy River Port
At Calstock, you’ll discover a place where history lingers gently in the air. Once a thriving industrial port supporting mines all along the valley, Calstock’s riverfront bustled with life, its quays stacked with goods and minerals heading to Plymouth and beyond.
Today, Calstock offers plenty to explore. There are beautiful riverside paths with views of the viaduct that are stunning from every angle, and you will soon be discovering some hidden gems in the mining landscape as the valley’s industrial past unfolds through a series of peaceful, atmospheric walks.
Just a short walk upriver lies Okel Tor, once a busy mining complex and now a Scheduled Ancient Monument. The remains of the arsenic and copper works sit quietly among trees, heather, and river views. Wander through the site and discover chimneys, foundations, and processing areas—remnants of what was once a vital contributor to the Tamar’s industrial wealth.
Another wonderful walk from Calstock leads into the Danescombe Valley, an enchanting wooded space with a fast-flowing stream that cloaks the traces of former mines, tunnels, and processing works. Once home to mining and later to the Danescombe pottery, the valley today is a tranquil place, filled with birdsong.
Cotehele: House, Gardens, and Historic Quay
No visit to the area is complete without exploring Cotehele, one of the National Trust’s most atmospheric estates. The Tudor house, perched above the river, appears timeless and almost untouched by the modern world. Its beautiful gardens, orchards, and woodlands add to the sense of stepping into another era.
But head down the path to Cotehele Quay, and the industrial Tamar comes into focus. Once a hub of river traffic supporting the mining industry and other local trades, the quay is now a serene, beautifully preserved spot. The restored warehouse buildings and the classic Tamar sailing barge Shamrock offer vivid reminders of the river’s working past.
This a landscape that rewards lingering, exploring, and returning again and again to lose yourself in the valley’s gentle magic.
