Naturists are also trying to break the world record for the number of nudists on a theme park ride.
Families are being invited to join in a nude swim session at Blackpool's Sandcastle Waterpark this weekend.
The skinny dipping event is open to adults and kids of all ages and is organised by British Naturism.
You can ditch your costumes and trunks to ride the water slides and wave machines in nothing but your birthday suit.
The session, from 6pm to 8pm this Saturday, is one a series of events by the group, with others happening at WaterWorld in Stoke-on-Trent.
It comes on the same day they're attempting to make a new Guinness World Record at Blackpool Pleasure Beach.
They want to have the most naked people riding a theme park ride at one time when they climb aboard the Grand National 5pm.
This is their 10th year at the Sandcastle and they're expecting around 300 visitors.
Its Facebook group says it 'exists to unite and support naturists, to protect naturist places and provide more, make social nudity more acceptable across the UK'.
Tickets for this weekend's event cost £21 for adult non members and £5 for children. Under fives go free.
