If you see a veiled Muslim woman sitting on a beach watching her husband and children splashing in the waves, don't assume it's her religion that keeps her from joining in the fun.
Muslim women can often be seen swimming while veiled - though they may not want to on beaches where most women are wearing bikinis.
The problem also occurs in some resorts in Muslim countries with an international tourist trade.
Expensive hotels in some Arab countries actually ban veiled women from their pools so that Western guests feel at home.
One answer for Muslim families who want to play in the water together is Halal tourism.
