Heartwood Forest is an extraordinary and special place that has transformed a vast area of former farmland in London’s greenbelt.
Thanks to tens of thousands of volunteers, over half a million trees have been planted and meadows have been sown. Heartwood Forest has become England’s largest planted native woodland, and wildlife is now booming here. Although Heartwood Forest is still young, its special mix of connected habitats – rare ancient woodland, wildflower meadow and new woods – makes it one of our top sites.

How to get to Heartwood Forest
Heartwood Forest (347 hectares/857.5 acres) is 4.8km (3miles) north of St Albans in Hertfordshire and only 32km (20 miles) from central London. It lies on either side of the B651, between Harpenden, Wheathampstead and Sandridge.
From St Albans, head north-east on the B651 and after 4km you will see a brown tourist sign pointing towards the car park from the main road.
There is a good train service to St Albans station, 4km (2.5 miles) from Heartwood Forest.
Visit National Rail for information.
The nearest bus stop is outside Pound Farm, opposite St Leonard’s Church. Walk through the farmyard and up the bridleway to reach Heartwood Forest.
Visit Traveline for more information.
Facilities and access
Heartwood Forest is close to St Albans, on either side of the B651 between Sandridge and Wheathampstead Village.
At 347 hectares (857.5 acres), there are several entrances to the forest, all linking to either bridleways, public or permissive footpaths. If you’re visiting Heartwood Forest for the first time, use the main car park entrance where you’ll find information boards and a site map.
There is a network of paths in Heartwood Forest including a public footpath and two bridleways. Most of the paths are unsurfaced and can get muddy when wet. There are some moderate gradients leading up from Sandridge village. There is a short surfaced all-access loop from the car park.
The car park surface is tarmac track with stoned parking spaces. An overflow car park is used on an ad hoc basis for events and exceptionally busy days. This is flat but the surface is grassed and can become muddy or waterlogged in wet weather.
There are eight bike stands in front of the visitor welcome and information point.
Announcement: Wells and Puddlers Woods are now temporarily closed. This action has been taken to prevent the loss of bluebells along the path edges. Due to wet ground conditions, there is a high risk that the paths will become much wider and thus lead to a loss of bluebells. The Woods will reopen in time for all to enjoy the bluebells in flower.
The Heartwood Forest car park is located off the B651, which runs from Sandridge to Wheathampstead.
There are 55 parking spaces available, five of which are reserved for blue badge holders. These are clearly marked with a blue badge logo. There are no time restrictions during opening hours on visitor parking here.
The car park is open from 8am all year round, but closing times vary depending on the time of year. Car park opening times: 1 January–29 February 8am-5pm, 1 March–28 March 8am-6pm, 29 March–30 September 8am-8pm, 1 October–31 October 8am-7pm, 1 November–31 December 8am-5pm.
The nearest public toilets to Heartwood Forest are at Sandridge Village Hall.
Wildlife and habitats
Animals
Look up to the skies at Heartwood and you may catch a glimpse of a rare and special bird. In fact, the total number of birds recorded here in the Breeding Birds Survey have more than doubled in recent years. Farmland species and birds of prey in particular are a common sight, such as skylarks and meadow pipits, and we also have some breeding willow warblers, a scarce species for Hertfordshire. Since 2012, 19 kestrel chicks and 60 barn owlets have been ringed in Heartwood boxes. Other rare birds such as the great grey shrike has also been spotted here, as well as hen harrier, grasshopper warbler and hawfinch.
Butterfly numbers have seen a three-fold increase here since we took on the site. We now have significant populations of the rare small blue and purple emperor, and small heath and marbled white butterfly numbers have blossomed.
Regular bat monitoring at Heartwood has revealed eight species of bat using the site, including the rare barbastelle. Small mammals such as yellow-necked and harvest mice also make their home here.
Heartwood is also one of only three sites in Hertfordshire to have stripe-winged grasshoppers. And although non-native, and generally well known to the south of England, the exotic-looking wasp spider was spotted here for the very first time in 2015.

Trees, plants and fungi
With a community orchard, an arboretum containing all 60 native tree species, precious ancient woodland and wildflower meadows, Heartwood Forest is rich in plant species. Over 200 species of flowering plant have been recorded here in all, with common spotted and pyramidal orchids beginning to appear all over the site.
Spot wood anemone and yellow celandine in spring, and admire mighty oak, hornbeam, ash, field maple, hazel, hawthorn and birch trees in all seasons.

About Heartwood Forest
While Heartwood Forest is a young wood, it has a rich history.
Acquisition
We acquired the 347 hectares (850 acres) of arable farmland on 30 September 2008, almost all of which was being farmed commercially with arable crops.
We started planting with the help of thousands of volunteers and school children. Three-quarters of the site is now covered with 600,000 native trees, all sourced in Britain. There are also areas of open space in the grasslands and wildflower meadows, a community orchard and an arboretum.

Archaeology
Archaeological investigations at Heartwood Forest revealed features such as depressions (possibly old pits), potential old tracks and internal banks. These, together with significant buried remains, suggest human activity from the prehistoric period onwards.
Trenches also showed evidence of late Iron Age and Romano-British activity.

Walking
As Heartwood Forest covers such a large expanse with a range of habitats, it is a brilliant place for a long and interesting walk. From wildlife wanders to magical meanders, a walk around Heartwood is well worth it.
Horse riding
Horses are welcome on both public and permissive bridleways that are clearly signed throughout Heartwood Forest. To avoid damage to the ground and plants, please stick to bridleways and avoid waterlogged paths to help prevent erosion or widening.
Horses are not permitted on footpaths, including the permissive paths through the ancient woodland. Please ride with care because bridleways are also used by pedestrians and cyclists.
