Raleigh Expedition - Adventure with Purpose. Raleigh International is not a gap year organisation; we are not a travel agency. Our mission is to create life-enhancing journeys and transformational experiences for young people. Raleigh International is a sustainable development charity. We harness the passion and energy of young people to effect positive change. Our programmes focus on providing access to safe water and sanitation, protecting vulnerable environments and building resilient communities. We operate in partnership with communities, non-governmental organisations and governments in 5 countries and in the UK.
