The trials will take place tomorrow and on Sunday at Belsay Estate.
The eventing trials will put equestrian experts through their paces in dressage, cross country and showjumping.
The cross country course is set over Grade 1 heritage parkland with a mixture of natural obstacles and permanent and portable fences.
The event, organised by Laura and Peter de Wesselow, was established in 2013.
It has grown every year and this year will feature dog agility classes, a display from Lammermuir gun dog team, fun fair rides and a climbing wall.
Belsay First School fair and games will also take place alongside a host of craft stands.
And treats will be on offer to suit all tastes from local providers such as Kielder Organic Meats and Wheelbirks Ice Cream.
