About
Berkhamsted and its neighbour Northchurch Common are the largest in the Chilterns at a combined 427 hectares. Northchurch Common is included within the Ashridge Estate and, between them, provides a large area of unspoilt grassland, heathland, chalks and woods to explore with your dogs.
The common also includes the Berkhamsted WWI training trenches, which should be one of the reasons to visit.
Dog-Friendly Policies
It’s a dog-friendly walk through the woods and heathland. Just be aware that there’s wildlife in the area (including deer) and a golf course, so it’s best to keep dogs on a lead if they tend to chase. As you can see from our photos above, in the summer, the trenches are pretty overgrown with heather.
It’s a low-key but fascinating spot if you enjoy a bit of history with your walk. And it’s a reminder of what soldiers were being prepped for, and not something you forget in a hurry.
Things To See & Do
Berkhamsted Common is open grassland, woods and a golf course. As you walk around, you will most likely see fallow deer and hear the squeaks of the red kites in the skies above.
The Berkhamsted WWI training trenches are a set of preserved and partially restored trenches dug during the First World War by soldiers from the Royal Engineer Training Corps and other units stationed in the area. The site was used to prepare troops for trench warfare before they were sent to the Western Front.
Between 1914 and 1918, thousands of troops trained on Berkhamsted Common, situated at the edge of the Chiltern Hills. The London Irish Rifles were among the first units to use the area. They practised digging and fighting in conditions meant to mirror those they’d face in France and Belgium. These weren’t just for show. Soldiers learned how to build defensive positions, lay barbed wire, and adapt to the cramped, muddy conditions they would soon face.
You can still see sections of the trenches today. Some have been cleared and preserved, allowing you to walk along them and get a sense of the scale and structure. It’s not like a full-blown museum, more of a quiet historical site hidden in the woods. There are also information boards, like the one in the picture below, to explain what you’re looking at.

Access and Facilities
There are many options when visiting, with car parks located along the road that passes through the commons. There is a free parking area by the War Memorial, where our marker is based. If you want facilities, you will be better served by parking at the monument within the Ashridge Estate, or if you want food and drink, visit the Bakehouse at Ashridge House.
It is also accessible from Berkhamsted train station, where you can walk beside the castle and the Berkhamsted Golf Course to enter the woods.
