Pupils take part in trips each term to visit various countries. Pupils have visited France, Germany, Spain, Ireland, the United States, Syria, Russia, Norway, Hungary, Uganda and several other countries. Exchanges take place as a part of the Modern Foreign Languages programme each year, with pupils spending time in France, Spain, or Germany and receiving a visit from their counterparts. Additionally, sports teams travel each year to various locations, which have included South Africa and Australia. Aside from trips abroad, extracurricular activities include the
Combined Cadet Force,
Model United Nations, a Debating Club, Wildlife Club, "Stock Market Club", "Model Rockets", and "Middle School Textiles Club". The school was involved in the establishment of the education charity United World Schools and since 2010 has funded a Partner School in Cambodia through co-curricular activities.

Combined Cadet Force open to pupils in Year 9 and above, which has Army, Royal Air Force, and Royal Navy sections.
Music In an article in the September 2006
BBC Music Magazine, the following was written about the music at PGS: There are several ensembles that perform regularly, many conducted by the school's associate conductor, Nicolae Moldoveanu. The PGS Chamber Choir sang at the Festival of Remembrance at the
Royal Albert Hall in 2005 and went on tour to
Salzburg at Christmas 2006. The Choir also sings regularly with the
London Mozart Players and upholds an annual tradition of singing Evensong at
Christ Church, Oxford.
Politics The school has run
mock elections for notable elections that have occurred at the time. In 2010, the History & Politics Department organised school elections for the
2010 UK election, where the school narrowly elected the
Conservative Party, whilst in the
2012 US election the school voted in favour of the
Democrats. ==Old Portmuthians==
