The beach is about 5 km away, so the map shows. In addition to the long distance, the problem is that there are no sidewalks and very few pedestrian crossings, almost none. Therefore, on foot it will be extreme. The transfer is frequent, if people do not fit, then the driver calls another bus by the phone. Well, if it's too late, etc. then you can get a taxi - there are a lot of them, a price tag for Ajman without traffic jams and crossing the borders of the emirates, is acceptable (although I never took a taxi, it was not necessary)
