The tea-room has it's own tea-garden and courtyard where you're welcome to sit and eat food and drink purchased in the tea-room, but if you've brought your own picnic then there's plenty of places across the park and garden 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. We have staff and volunteers working on reception and by the bus stop and main courtyard who can help point you in the right direction should you get lost.
Here are some of our top pics of places to have a picnic:
The West Garden
Find a shady spot around the pools in the formal West Garden or in the shadow of the Saxon church and 17th-century house, surrounded by flora and fauna and beautiful butterflies. There are plenty of benches dotted around and picnic rugs for sale in the house.
Old Lodge natural play area
If sitting on the grass isn't for you, Old Lodge has hay bales and picnic tables and lots of things for children to do - balancing beams, climbing frames and a beautiful allotment. A gated area, you can enjoy a family picnic - while your little ones play.
Perry pear orchard
Our perry orchard and wildflower meadow, which joins the main West Garden, is a wonderfully serene place to enjoy a picnic. Please, just make sure you stick to the main paths so as not to disturb the wildflowers which come to life in early summer.
There is no shortage of space in the 270-acre deer park but there is no better backdrop for your picnic than our viewpoints to the North (Journey of Discovery Trail) and South (Prospect Walk), which look across the Bristol Channel and into Wales.
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. Later on in the day, the deer often gather in this area.
Whitefield wildflower meadow
One of Dyrham Park's hidden gems, the large wildflower meadow next to the car park is full of colourful blooms and characterful grasses in the summer. You're also welcome to take dogs into this area (but not into the main deer park).
The Lost Terraces
If you want a bit more shade from the blazing summer sun, head into the Lost Terraces - a fairly recently-opened area which joins the garden to the park. There's a flat which overlooks the garden with carved log benches and plenty of space to enjoy a picnic.
