Dewstow Garden and Grottoes


Wednesday, 8 September 2021 at 2:00 pm - 4:30 pm

A visit to Dewstow Garden and Grottoes, Caerwent, Caldicot. NP26 5AH.

This is a garden featuring many rock gardens, ponds, water features and trees, but it is only when you go below ground and you enter the subterranean world underneath that the skill and vision of the founders are revealed. This unique 21st century garden, one of Wales’ hidden gems, is one of the lesser known attractions in South 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, waterfalls and pools, and beneath all this, a labyrinth of tunnels and grottoes.

John will give a short introductory welcome and talk about the history of the gardens before e are free to roam and explore. Refreshments will be available to complete our visit.


We have looked into providing transport for these visits but the costs and complexity of the Avon area prevent us from achieving an affordable outcome.  We operate a car share scheme for all AGT events where possible. Arrangements for any visit can be made through Peter Hills and every effort will be made to couple up attendees where requested.


For bookings on all events, please contact Peter Hills – [email protected]; phone 07748 507 166 [Mob] for details; or email / post the attached booking form.


The owner has requested that face masks be worm in the reception area, toilet area and grottoes.

There will be a one way system in place through the tunnels and grottoes and visitors are encouraged to adhere to social distancing in the gardens. Some small areas have been closed where this is not possible.

We are requested to adhere to Welsh Government Covid 19 legislation at all times on our visit.
