It is huge fun if you have kids and quite interesting if you don't.
However its a place you go when your on holiday, I obviously don't know how far away you live but I wouldn't travel a huge distance for a day.
Its a working farm - but you get sheep sheering demonstrations - a look at an awful lot of different sheep - There was this guy who did amazing things with horses, they have there own brewry and the highlight of the day Sheep racing.
I have been twice and enjoyed it immensly worth a vist but maybe not worth a trek.
