Stretching over North Tyneside Council's boundary into Blyth, the Dene is jointly managed with Blyth Valley Borough Council.
Declared as a Local Nature Reserve in 2003, the Dene has a number of interesting habitats that can be explored along its entire stretch.
These include oak-ash woodland, beech woodland, ponds and wildflower meadows. In the woods pipistrelle and noctule bats have been detected, whilst the Seaton Burn watercourse running through the site supports species such as otter and kingfisher.
The site holds significant ornithological interest, supporting bird species such as great spotted woodpecker and tawny owl.
Other birds recorded in the Dene include song thrush, tree sparrow, yellow hammer, dunnock and blue tit.
The ground flora is typical of this type of woodland, although in the past cattle grazing severely reduced the variety of plants found.
However, cattle are now excluded from some sections of the Dene and this has helped to regenerate those areas and improve the overall richness of the ground flora.
Wood anemone, dog violet, primrose, bluebell, garlic mustard and buttercup are just some of the wildflowers that can be seen.
Access to the Dene is via the B1325 (Hartley Lane), where a small car park offers limited free parking.
