In a first for Liberal Judaism's Kadimah summer camp, participants were joined by a group of boys from Luton Central Mosque for a day of learning and games.
The Jews and Muslims played football and board games and enjoyed lunch in a tent on the lawns of the camp at Cottesmore School, near Crawley, West Sussex. They then spent more than an hour in a large informal discussion, asking one another questions about the differences - and similarities - between Judaism and Islam.
Youth leader Jeremy Wilson, 18, said the discussions had taught him a great deal about Islam. "Although there are a lot of differences between our religions, there are also a lot of correlations."
Ashvag Ahmed, a youth worker at the mosque, said he hoped to arrange a reciprocal visit - and to return to the camp with another group next year.
Liberal Judaism chief executive Rabbi Rich said: "I'm thrilled the visit was such a success for both the Muslim young people and our own youngsters. It shows once again that Liberal Judaism not only talks about interfaith dialogue but also plays a practical part in seeking to create a better society here and abroad for the generations to come."
