About the garden

Imagine discovering a lost garden with tunnels and underground grottoes buried under thousands of tonnes of soil for over 50 years. That’s what happened at Dewstow gardens. Built around 1895, the gardens were buried just after World War Two and rediscovered in 2000. An incredible restoration job now sees all back to former glory.

Opening times

24th Mar - 4th Nov 2018 Open daily from 10am until last entry at 3.30pm.

I fell in love with the brochure long ago and eventually went 7 years ago. This is amazing, it’s beautiful and it’s not over run so you can really enjoy the serenity of the place. Great parking too. My favourite place to go no doubt. The prices are great for a wonderful day out.

Wow, what an experience! The gardens are superbly maintained and the caves are a delightful experience. For those of us who are a little unsteady on our feet parts of this may be tough, there are handrails along most of the trails but not everywhere so be warned. The coffee shop is not to be missed with good coffee and a choice of great (Kirkland) carrot cake or hot sausage rolls.

We visit regularly and we absolutely love it there! Friendly staff gorgeous gardens, beautiful grotto. Great cakes at the cafe! Maybe some more veggie choices as only sausage rolls and pasties for meat eaters :( We will be back°

The gardens are well kept and we really enjoyed finding the hidden objects. The parking is free and the entrance fees are reasonable for the amount of work I imagine that goes into tending the gardens. Thank you for giving us a unique experience!
