After passing his A levels, Prince William took a gap year. That means he had a one year break before going to university.
He spent the first part of it in the Belize jungle sleeping in a hammock, wearing jungle combats, and eating army rations.
He also worked on a farm in the UK before travelling to a remote part of Chile.
As a volunteer for the charity Raleigh International, William helped build new walkways and teach English in a mountain village in the south of the country.
