I have just added this to the map of places to fly your drone at Drone Scene:
Land owner permission not required.
This is managed by The Parks Trust, who have a very positive policy on recreational drone flights (https://www.theparkstrust.com/media/9086/tpt-10-77-recreational-and-commercial-drone-operator-policy.pdf)
You will probably notice that the site is immediately adjacent to a large airspace restriction (EGR214 Woodhill) but this is only applicable to helicopters so is not relevent to drones.
There is a small car park at ///motivates.masters.pushy, and the TOAL I used was a couple of minutes walk from there at ///expert.greed.stutter.
The originator declared that this location was not inside a Flight Restriction Zone at the time of being flown on 10/08/2023. It remains the responsibility of any pilot to check for any changes before flying at the same location.
