Yes it is. Lots of different routes to take.

Yes you can do now all there is a 2 pound day ticket witch the bailiff will come round and give you a ticket

There is fishing allowed on nearby canal.

Further to the reply about copious wildfowl droppings i'd add that thats the situation around the ponds and there are plenty of similarly fine wide paths into and through the woods and up to the cemetery or across the river and then up or downstream. those up to the cemetery are steepish and will require a fair push but its all tarmac surface on those. the paths up and downstream provide lots of opportunity to follow the canal and its many interesting features on a level path thats also pram friendly but not surfaced. following these paths provide ample opportunity to return to the town or other access points for parking that allow many visits for different routes to be explored.

There's a road just uphill from the park that is a dead end and importantly it borders the park itself but wide enough for easy parking by large and high vehicles as it has the odd industrial premises on it and even a snack shack sometimes, do a google street view to get appreciation of the convenience but its pretty close and horses wouldn't need to trot down roads with cars on to reach the park.

Hi sorry for the delayed response. It is dog friendly if your dog is on a lead unfortunately. This is just down to restrictions because of young children and other wildlife. However, having said that whenever I have gone I have seen plenty of dogs off the lead, running around and having a great time. These seem to be well behaved dogs so I also thing that the wardens etc turn a blind eye to these. I hope this helps a little. But yes, they welcome you there with your dog. :)

Yes gates and drive security around.nothing to see at night.

Not seen any signs saying "you can't" so guess it's ok as long as you tidy up and don't damage the grass or trees
