Dewstow Gardens & Hidden Grottoes, Caerwent

#1 of 12 in Parks in Monmouthshire
Must see · Garden · Nature / Park
Dewstow Gardens is one of the least known of all the attractions in southern Wales, but also one of the most interesting. The gardens are a wonderful place to wander in themselves, with beautifully landscaped paths and decorative beds, articifical waterfalls and man-made pools, but it's Dewstow Grottoes that make this place really fascinating.

It’s astonishing to think that, only 10 years ago, this strange and wonderful garden was buried beneath thousands of tons of soil, lost and forgotten for over half a century.

Built around 1893, Henry Oakley created a garden – his own personal wonderland – that was described by the few who visited as a “magical and wondrous place”.

When Oakley died in 1940, the gardens fell into disrepair, and were eventually buried and returned to farmland just after ww2. After a huge excavation and renovation project beginning in 2001, the gardens are now open to visitors during the summer months.

  • We were amazed by this garden (Grade 1 listed). Had to visit on a rainy day as it was the last day of the season it was open. Cost £7.50 for an adult and well worth it. Opens at 10 am with last...  more »
  • Unexpected hidden gem in South Wales. From stepping stones to ponds, waterfalls , rock gardens, grottos and tunnels. Fantastic the way it is all laid out and how everything has been incorporated...  more »
  • Such a beautiful place. We visited with my little one and she loved it. Exploring the grottoes, over the stepping stones finding all different objects for the kids activity sheet. It's so lovely, fish swimming around, waterfalls, plants and flowers everywhere looks like something you'd see in a film. The gardens are amazing. Lots of little walk ways around to find different ponds and waterfalls. We took a picnic but they do have a café. Staff were lovely too. Also a huge plus under 5s are free.. Lovely day out.
  • This was a lovely find , with understand tunnels it proves to be very exciting for little ones .The gardens do a treasure hunt trail. Which our daughter enjoyed and was rewarded with a treat by the gardens for completion . Lovely gardens to spend a couple of hours on a Summers day .
