We recently visited this wonderful national trust property and would thoroughly recommend it.
It was our first visit to a national trust property and it was money well spent.
Car parking was available on site (pay and display) and entry was via the national trust visitor ticket office. A courtesy vehicle is available for those who are mobility impaired.
Enthusiastic volunteers and staff really make this trip worthwhile, with their in depth knowledge of the property making it all come alive. The house itself is huge and so many rooms which conjure up visions of a bygone era. Hugely cute were the small groups of children going through the house all dressed in period costumes solemnly learning about the inner workings of the kitchen or the table settings in the massive dining room.
There is a gift shop and restaurant on site. We didn't visit the restaurant after seeing the menu offerings and prices (fairly basic fare - sausages and mash).
The deer roam freely in the grounds of petworth, and would have been a delight to see had rain not poured down.
The gardens are well worth the visit alone, with the amazing landscaping.
Turner's paintings are of course another highlight.
If you have children, there are dress up closets and other child related activities, so don't hesitate to take your children.
