I have just added this to the map of places to fly your drone at Drone Scene:
Land owner permission requirements unknown.
I used the public footpath that runs around the Slipper Pond. Parking in Emsworth is by chance, I drove slowly past the Lord Raglan pub which is where the footpath originates and no on-street sopaces. I found a space in King Street, walked back and sure enough, a space big enough for a bus had appeared outside the pub!
Parking is free but time limited. Pay-to-stay public car parks are available around the town. The footpath runs through some up market properties and through a kissing gat to a metre wide hard stone path bordered by grass. You will have to hand launch and catch if you use the path as I did and smile at the dogwalkers and hikers while ignoring the swans that think that you are there to feed them.
You get a good view of the sky so VLOS isn't a problem and there is a lot going on in Emsworth. It's one of the major sailing centres in Chichester Harbour. Other TOAL points are available in the town 
The originator declared that this location was not inside a Flight Restriction Zone at the time of being flown on 10/02/2023. It remains the responsibility of any pilot to check for any changes before flying at the same location.
