A Cornish parish council is considering leasing part of a beach to the Ministry of Defence to stop nudists going there.
The MoD banned nudists on nearby sand dunes in Penhale, Perranporth, last year over fears the area was attracting people looking for sex.
Perranzabuloe Council owns the beach itself and the MoD would like a similar ban implemented.
The army, which has a base nearby, wants to ensure young cadets are not shocked or offended.
Cadets and schoolchildren are among the 6,000 people a year who use the Penhale training area.
Major Michael Pawlak, commandant of Penhale Camp, said of the ban last year: "Naturists are not the problem, it is the perverts they attract that are the problem."
However Brian Williams of the Central Council of British Naturists said the authorities should be getting rid of the voyeurs, not the nudists.
The council will meet army officials next week.
