We are a team of language teachers and leisure instructors. We have been organizing summer camp Peira since 2007. Although the camp is organized primarily by Czechs we cannot forget to mention the collaboration with colleagues from the Great Britain.
In terms of summer camp we use our long-time experience in teaching to offer an extraordinary and interesting side of the Czech Republic to children.
