Take a look around Cowroast Waterside & Marina


A picturesque base on the Grand Union Canal

Situated on the Tring Summit of the Grand Union Canal, Cowroast Waterside & Marina offers you a secure mooring in picturesque surroundings. Cowroast is a good base as it's on a lock-free stretch of canal, it’s also a perfect spot for cruising with friends and enjoying the views. Surrounded by fields and footpaths, with the local towns a short drive or bus journey away, you might be surprised to discover that that the nearest town, Tring, is just 46-minutes from London by train. The name Cowroast comes from "Cow Rest" and it was where the Romans would rest cattle on their way to Londinium. A Roman helmet found locally is in the British Museum.

Things to do in Hertfordshire and nearby

The natural setting of the marina hints at the wonders of nature nearby. Visit Tring Park, 328 acres of broadleaf woodland, wildflowers and open vantage points with far-reaching views. Go birdwatching at College Lake Nature Reserve or see the countryside for miles from the breezy heights of Ivinghoe Beacon. In Tring, discover nature’s past and present at the Natural History Museum, meander along the High Street, browsing the independent shops, visit the medieval church of St. Peter and St. Paul, or watch a film at Tring popup community cinema. For an adventure, pack a picnic and spend a day discovering the Chilterns or, for a complete contrast, hop on a train for a day trip to London.
