The event celebrates the British countryside and rural communities and is a landmark in the agricultural calendar.
There are a number of new attractions for 2017:
Wellington Boot Theatre
Visitors will learn about the great outdoors in the new theatre, hosted by BBC Hereford and Worcestershire presenter Andrew Easton. Showgoers will be inspired to try new outdoor activities and there will be the chance for Q & As with Andrew and his guests, including BBC Countryfile presenter and show ambassador, Adam Henson, world championship cyclist Tracy Moseley, Caroline Corsie from the Worcestershire Wildlife Trust and England and British and Irish Lions rugby player Geoff Parling.
Country Pursuits Village
The village is designed to give a real feel of country life. Entertainment planned includes falconry, animal displays and country sports demonstrations. Visitors will also have the opportunity to 'Meet the Countryside' and demystify any puzzling country myths.
Ask the Farmer
In this area showgoers will be able to speak to a range of people from the farming industry and gain a greater insight into the wider farming industry and how the food on their plate is produced. Coordinated by the Rare Breeds Survival Trust, the area will feature breeds native to Gloucestershire, complemented by talks and demonstrations by experts in the industry. Adam Henson will speak on each day of the show as well as conducting book signings in the Wellington Boot Theatre.
Medieval Active Camp
Hosted by the Woodvilles Battle Re-enactment Group, this medieval living village will offer children the chance to dress up as a soldier, participate in authentic medieval games and walk through Gloucestershire's famous battles.
Gloucestershire Hotspot Trail
Another family-friendly activity, there are 15 hotspots to find across the showground, each celebrating the greatness of Gloucestershire. Visitors are invited to solve the anagram and claim a prize from sponsors Western Power Distribution.
MAKING A WELCOME RETURN
The Main Arena entertainment has a packed timetable headlined by the daring Bolddog Lings FMX team, live music from The Band of The Prince of Wales's Division, displays from The Red Devils and a Grand Parade of livestock.
Showgoers will be able to see fine livestock, meet the farmers and watch over 3,000 animals compete to be crowned champions. The Young Farmers group will inject a healthy amount of fun into proceedings with humorous competitions like an Adam Henson look-a-like contest and Tug of War.
Food Glorious Food
Food and farming go hand in hand and the Royal Three Counties Show will whet the appetite of the finest foodies. Showcasing the best of local produce, the food and drink hall will offer a host of tasty treats to try, while the Cookery Theatre welcomes local chefs to the stage. There is also the new Three Counties Cider Festival and Garden and a Cheese & Dairy Produce Show.
In the livestock rings the focus will be on some of the country's finest sheep, cattle and pigs, with the show this year hosting visitors from across the world as part of the World Angus Forum. Delegates from all the major cattle producing countries will be at the show on June 17 to watch the championship classes from the Aberdeen-Angus Cattle Society's Summer National Show.
This year there is a record entry of more than 2,700 sheep entries across both the main show and the National Rare and Minority Breeds Show which takes place on June 19. Among the cattle entries will be the new National Junior Dairy Show featuring classes for all the major dairy breeds.
