Nearly 500 nude sunbathers will need nothing more than a towel and a smile to take part in a three-day, two-night nudist party celebrating “clothes freedom” at a United Kingdom water park.

A United Kingdom nudist group will take over the Alton Towers indoor water park for a private weekend of swimming and socializing in late November 2020.

​”Nudity is permitted 24/7 giving you two nights of clothes freedom,” boasts the British Naturism website.

The nudist event is set for Nov. 20-22 when the U.K. theme park is closed to the general public, according to the local Stoke Sentinel.

The 2020 British Naturism outing will mark the 14th year for the annual Alton Towers water park event.

British Naturism, a U.K. group of naturists, hosts a number of nudist events at water parks throughout the year.

Can’t wait until November? Start your year with a skinny dip during the Happy Nude Year event hosted by British Naturism on Jan. 4 at Oasis Beach water park in Bedford, U.K..

The cost for the Alton Towers water park nudist weekend is $484 (£365) for a large family room and $152 (£115) for each additional guest. Children under 18 years old are $73 (£55) and kids under three are free.
