There are a few tables and chairs in the courtyard and in Fountain Court where you can sit and eat food and drink purchased from the tea garden kiosk, but if you've brought your own picnic then there's plenty of places across the site to enjoy a spot of al fresco dining.
The National Trust shop sells rugs and other picnic essentials, including reusable cups - so don't worry if you forget to pack these things.
Here are some of our top picks of places to have a picnic:
In the middle of the parkland, Old Lodge is a perfect place to picnic with tables, some of which are undercover. It's a great enclosed area that children can explore and there's an old tractor parked up for some imaginary play.
The garden team have mowed a few areas especially for you to enjoy your picnic so you can sit in this beautiful surroundings and take in nature while you eat and drink. Please help us to help the plants and flowers continue to thrive by keeping off the unmown spots.
The East Front
One of the first things you'll see when you come down the drive into Dyrham Park is the 17th-century house, which has a wonderful grassy area in front on which you can enjoy a picnic.
The car park
There are a number of large picnic tables at the edge of the car park under the trees.
