pre,

it's very easy, when you go to al khor (from D ring road all the way to land mark) use this road straight towards al khor.. before reaching al khor exit on your right you will find al sumaisimah exit.. remember this exit is BEFORE al khor exit.. then go straight until you reach sumaisimah community/village.. the beach is just close to it.. this is the coordinates and check it using google earth ---> 25°34'26"N, 51°29'17"E.. my family is visiting the place today as i have heard good news about sumaisimah family beach...
