Top pick34 farms across Loudoun
Saturday 17 October – Sunday 18 October · 10am–4pm
FreeAll agesOutdoor

Thirty-four farms open their gates for free, with goats, alpacas, donkeys, a dairy with ice cream and farmers happy to talk. It's the best free weekend Loudoun does all year.
- Parking
Each farm parks you on its own land, often on grass, so wear shoes you don't love. Organizers say some farm stores sit apart from the farm itself, so follow each farm's tour signs.
- Arrive
At 10, at your farthest farm, then work back toward home. Farms close at 4.
- What it costs
Free, no tickets. Bring a card or cash for extras: an ice cream cone at Brookfield Dairy, pumpkin decorating at Danny's Dream Acres, lunch from the food truck at The Sassy Ass.
- Crowds
Organizers say thousands come to every tour, and don't break it down by farm. Mornings beat afternoons almost everywhere, and Sunday is the same tour with the same hours.
What to know before you go
Our three for kids: Brookfield Dairy (cows, calves and a milking demo at 1:30 both days), Rivenwool (feed the sheep, goats, geese and ducks) and The Sassy Ass (miniature donkeys and a free s'more at the fire pit). Double 8 Alpaca asks you to leave dogs at home. Printed farm lists are at most county libraries.

Saturday 17 October · 2pm–6pm
$5 a person, group discounts availableAll ages

Hayrides, a hay maze, a not-so-scary haunted house, spooky storytime and a lineup of decorated trucks. Your under-8s will absolutely love this.
- Parking
Park in the museum's own lot off Heritage Farm Lane. If it's full, there's overflow parking next to the ballfields. Claude Moore Park has several entrances, so aim for the museum's.
- Arrive
At 2, when it opens. Online sales close Friday at 5pm; miss that and you can still buy at the entrance gate.
- What it costs
$5 a person, grown-ups included, with group discounts. A family of four is $20 before any discount.
- Crowds
The museum doesn't publish numbers. Four hours is a long window, and earlier beats later almost everywhere.
What to know before you go
Buy online by Friday at 5pm, or at the gate on the day. It all happens outdoors, so dress for the weather. Parents rave about the indoor exhibits, including a cow you can practise milking on, but the museum is closed during the party. Save the cow for a quieter weekend.

Saturday 17 October · 4pm–7pm
$5, under 2 freeAges 3–12

A trunk-or-treat, games, crafts and pumpkin picking at Ashburn's big new rec center, for about the price of a coffee.
- Parking
The rec center's own lot. Nobody publishes event-night numbers, so come at 4 and take a space near the door.
- Arrive
At 4, for first pick of the pumpkins.
- What it costs
$5 a child, under 2 free.
- Crowds
Not published. It spreads across indoors and out, though one parent says the main hall gets loud. Ear defenders for the sensitive ones.
What to know before you go
Ages 3 to 12. It runs indoors and out, so a passing shower won't sink it.

Saturday 17 October · 7pm–9:30pm
Free, registration requiredAges 10+

Timed groups walk a haunted trail through Loudoun's only nature preserve after dark, and anyone who makes it back gets a treat bag. This is the real scare.
- Parking
Free, and one visitor mentions two lots. The county says to meet at the Education Annex, so park nearest that.
- Arrive
Groups go in first come, first served from 7 until 9:30, so 7 means less waiting.
- What it costs
Free, but advance registration is required.
- Crowds
Timed groups keep the trail from bunching. The line at the start is the only crowd, and it's shortest early.
What to know before you go
Recommended for ages 10 and up. Expect darkness, loud noises and jump scares; the county leaves the call to parents, and so do we. Under-16s need an adult. One visitor warns about ticks at the preserve, so spray before you go.
