Walk 90: Heartwood Forest Long Loop

4.9 miles (7.9 km) with 76m total ascent

The path between points 14 and 15
This is a picturesque and varied walk taking in a part of Heartwood Forest that attracts fewer walkers - probably because it’s further from the car park. The route, one of our favourites, passes through the eastern section of the forest which is an area rich in wildflowers and butterflies. In this area you will also find a communal orchard of native fruit trees, and an arboretum laid out with several distinct areas of native trees.

According to the Woodland Trust, Heartwood Forest is the largest continuous new native forest in England; “a place where everyone can find space, peace, wildlife and miles of beautiful woodland to explore.” This ramble follows the outer edge of the site passing through the village of Sandridge where you can find refreshments at three pubs and a village store with a cafe. There is also a pub a short detour close to the halfway point.

This route was first published in August 2019 but was rerouted in July 2025 after part of the walk was fenced off to protect nesting skylarks. Other changes to the original route were also made.

Nesting skylarks

There are several sections between points 5 and 11 and between points 17 and 18 where there are signs asking dog owners to keep their pets under control because of nesting skylarks. Sadly, on the day we tested this revised route, one woman was throwing a ball into the grassland beyond the sign resulting in her pet bounding through the nesting area. Such a pity. Skylarks typically nest on the ground between April and August and can raise two to three broods during this time.

  1. Lovely easy walk across gently undulating countryside. Instructions were perfect, easy to read and follow! Highly recommend The Green Lion pub for a bit to eat at the end.

    1. Glad you enjoyed the walk. We often head up there for a stroll. I think you meant The Green Man pub, which we really like. The food and beer are excellent. Thanks for the feedback. David
