What to know before you go
Because this is one of the largest summer events in Northern Virginia, arriving earlier in the day or before evening entertainment begins can help you avoid the biggest crowds and secure parking more easily.
Since much of the fair takes place outdoors, dress for the summer heat, wear comfortable walking shoes, and bring sunscreen.
Staying hydrated is especially important if you’re planning to spend several hours exploring the midway.
It’s also a good idea to bring some cash, as certain vendors, games, or attractions may not accept every payment method.
Families with younger children should consider bringing carriers or strollers, as the fairgrounds are expansive and there is plenty to see throughout the day.
How much does it cost, and where can you buy tickets?
Admission prices vary slightly depending on the day, age, and ticket package selected, with options available for general admission as well as ride-inclusive passes, but generally adult tickets are $25 per day and children tickets are $15.
Children ages 4 and younger receive free admission.
Purchasing tickets online in advance is recommended, particularly if you’re planning to attend one of the fair’s most popular nights featuring monster trucks, demolition derbies, or fireworks.
Carnival rides and any separate attractions not included in the general admission tickets will be available purchase on site once you arrive at the fairgrounds.
