Joss Bay, near Broadstairs is very good late evening. Lots of dogging action viewing here.
The carpark at entrance to Chilham-toilet which is open all night. Some gays, some couples.
Dover The car-park on top of the cliffs, overlooking Eastern Docks. At night, go past the toll booth and take the left up into coach park. Good dogging and exhibitionism and nice views too!
Isle of Sheppey
Leysdown Naturists beach and car park. Drive onto the Isle of Sheppy. Follow signs to Leysdown. Through town, follow the coast road until it appears to end. Turn left down the unmade road. Over the hump. Park up. Over the grass bank is the naturist beach. Both the beach and car park can get "interesting" later in the day.
In the car park near the cafe in Oxleas Woods, which is the top of shooters hill. Turn left into Kenilworth Gardens and left again down the drive to the car park. Best suggestion is to park on the far left hand side, on the grass area which is just off the car park, near the wooded area. Good couples dogging action here.
Lay-by just before the new bypass on Gravesend Road near Strood, the A226. Action most nights after 11pm.
Shoreham woods near Junction 4 of M25 is a good place, fairly quiet but some couples action. Shoreham woods ( Brown picnic signs ) located off A224. Leave M25 @ J4 up to first r/bout, sharp left on to A224 to Halstead/Badgers Mount. 2 miles to first r/bout, turn left into small country lane. Shoreham woods on right set back off road. If you end up going back under M25 you have missed it!
Dover, Western Heights
Above the cruise terminal follow signs for folkestone then western heights, up a windy hill (past European freight depot) car park on the right as you go up and a pinic area just round the corner on the left, also some old ruins.
