I have just added this to the UK Map of places to fly your Drone at https://dronescene.co.uk
This is a very nice place with different views possibilities. You can flight across or along river Thames, you can reach Dartford Crossing, there?s boat harbour too and all surrounding area is amazing. You need to leave your car and have around 10 minutes ealk to destination. Contact me if you want to get accurate location but it?s straight north from the map point towards river Thames via public footpath.
