Skinny Dipping at Longniddry Bents 1, East Lothian

Parking:

Park at Longniddry Bents 1 Car Park. Nearest Post Code is EH32 0PN (though don't follow it all the way as it sends you the wrong way).... From the A198 turn left down Dean Road and then right on to the B1348 and then immediately left into the car park. Best using https://what3words.com/body.icicles.splints or https://goo.gl/maps/VX8XpPgd2pDHEUC99
Cost £2.50 via cash machine (also takes card via RingGo 21000). Mobile signal is patchy in that area.... so check you have cash just in case. Though, if you are intending to use East Lothian beaches a lot then they offer a season ticket for £50 (order online). The car park is very busy at weekends on hot days so it is recommended to avoid going between 11:00am and 3:00pm on Saturdays and Sundays during the summer. No parking is permitted between 10pm and 6am.

Buses:

Lothian Buses No 26 stops just 200m west of the beach (at Haven Holidays Seaton Sands)

Swim Spot:

There is just a short walk of 5m from the car park to the beach. It is not a nudist beach and will be busy with families and dog walkers most of the time. So you either have to go for a quick skinny dip first thing or just before the sunsets.
The tide goes out almost all the way to Fife (or so it seems) at low tide so.... take a camping chair to put your clothes on. No one will see you at the shore line when the tide is all the way out - especially as the sun is setting as you'll be silhouetted. However, it does remain very shallow until about 50m out so you may need to wade in quite a distance before you can swim.

Safety:

The water can get quite rough on windy days so just take care. There are a lot of hidden rocks.. so stay in the middle area of the beach. Just watch for jelly-fish in the summer... though there really aren't many to worry about. Be aware that the tide will return in quickly and may engulf your clothes...
The water is fairly clean... but there are 2 sewage pipes going into the water: https://forthriverstrust.org/sewage-outfalls-around-the-firth-of-forth/ (see map)
