Our incredible bluebells

The bluebell display at Dinefwr really is a treat for the eyes and nose.

Every spring, Castle Woods is carpeted with thousands of beautiful lilac flowers that grow in a race against time before the leaves return to the towering tree canopy, cutting off the sunlight once more.

If you're visiting out of the bluebell season, this walk is still well worth a visit. Learn all about Dinefwr Castle and enjoy some breathtaking views.

Thousands of new trees have been planted to maintain wildlife habitats

Some of the oaks in the deer park have been growing for 700 years.

They've been home to generations of beetles and lichen. The trees at Dinefwr are left in place to die slowly, as dead wood is a rich habitat for many insects. We've planted thousands of new trees to make sure there's a ‘continuity of habitat’.

Life in the lichens

For over 20 years the magical deer park has been managed to encourage lichens and beetles.

More than 160 lichens have been recorded on the deer park trees, making it the most important parkland site for lichens in South Wales. As well as this, over 400 species of beetle live here. Dinefwr is one of the top 20 sites in Britain for invertebrates that depend on dead wood.
