The week-long Nudestock X event, in its 10th year, is taking place from Friday May 24 to May 31 at Candy Farm Camp Site to the east of the town.
Revellers camp for the week and enjoy numerous activities in the nude.
A spokesman for the event said: “Booking is going well for the popular Yorkshire and East Midland Regional camping event.
“It wouldn’t be a British Naturism event without a theme, and this year it will be ‘Space’ to celebrate the 50th Anniversary of the lunar landing.”
“We have great fun and everyone has a really relaxing time together”
Games such as races, sport and crafts are enjoyed while even yoga takes place.
Live music in the evenings and BBQs are also had – all while completely starkers.
Long-time naturists Colin and Carol Wood and daughter Angie Cox were among those getting their kit off last year.
Colin, 65, told Doncaster Free Press last year: “It is always a good week.
“We have great fun and everyone has a really relaxing time together.”
He added: “People think we walk around naked all day every day, but we don’t.
“We just sit around talking about everyday things and doing everyday things.
“We just don’t happen to have any clothes on – that’s the difference.”
This comes as last year British Naturism recorded a “huge rise” in membership applications.
There are over 9,000 members of British Naturism, which started in Northampton in 1964, who pay the £40 annual subscription.
The group’s Facebook says it “exists to unite and support naturists, to protect naturist places and provide more, make social nudity more acceptable across the UK”.
The organisation reckons we are becoming “more comfortable in our own skin and shedding stuffy Victorian values”.
Spokesman Andrew Welch said: “We’re all human. What better way to escape the heatwave than cooling off without clothes on?
“We’ve seen our membership going up as people have appreciated what you can gain from naturism.
“We are not so buttoned up as we used to be.
“There’s a good chance that many of your readers indulge in it whether they are members of our organisation or not.”
The group has proved controversial among some with 4,000 people signing a petition for a naked swimming event earlier this year in Stoke-on-Trent to be banned.
But Welch hit back saying naturist family swimming has been “in existence for decades”.
