Knebworth house, gardens and park is a brilliant family day out. The grounds are huge, the gardens are interesting, and the house is beautiful. You can park the car by the house and gardens, and also at the bottom of the park. For the kids, there is a huge adventure playground (best to do this on the way out as it's right at the bottom of the park, miles from the house and gardens), which has a good range of play equipment for pretty much any age range. In the summer they have a free bouncy castle too. The gardens are seperated into different areas, and it is all very well signposted so you won't get lost. The dinosaur garden is really good, and the kitchen garden smells heavenly in the right seasons. There is a fun maze too. The house itself is really beautiful, and you can pay extra to have tours. I could go on forever explaining everything here, but I won't. Rest assured it is well worth the entrance fee. The cafe is really expensive so take a picnic! read more
