Well the signs state no. However if they are on a leash and you clean up after them. I see no harm. We always take ours

Thankyou for your question, im afraid BBQ's are not allowed in Castle Park

It depends on which direction you approach from, but if your route is up East Hill (from the Harwich, Ipswich or Clacton direction, head up towards the bottom of the High Street (with Hollytrees Museum and then the War Memorial, on your right), follow the road left at the traffic lights, down Queen Street and turn 2nd left into Priory Street to the long car park there ( just under the old town wall). Ticket machines will display the charges. For Lower Castle Park on foot, retrace your route back up Queen Street, to the War Memorial and across into Upper Castle Park, take any of the paths down the hill behind the Castle through the park gardens, to where Lower Castle Park lies at the bottom. There is also the Nunns Road Car Park (behind North Hill), which is closer, but I have never used that one. Hope those help!

It's free to get in. Some events have paid entry but this is rare and never shut the whole park.
