Despite recent threats by the Tel Aviv Municipality to close six of the city's 13 beaches due to a labor dispute with the lifeguards, the city's beaches have been given an international thumbs-up by National Geographic in a recent list of "10 Great Urban Beaches."The list, originally published on the Smartertravel.com website, writes: "If Jerusalem is Israel's responsible, buttoned-up firstborn child, then Tel Aviv is the fun, freewheeling youngest sibling. On warm days, Tel Avivians are quick to hit the city's 13 beaches that span more than eight miles along the Mediterranean."
