I think the condition of the beaches changes everyday depending on the wave action. We were down there the last week of Nov. There was much construction going on still in the hotel zone and not much beach left.
Los Muertos beach was great however. This was just 1 month after the hurricane. We went back for Christmas week and were surprised at how little beach there was on Los Muertos. The waves were huge though. Seems there has been a lot of wave action since the hurricane and the beaches are changing from day to day. They say that with time the beaches will return. We went to Destileradas Beach Christmas week and it was gorgeous!
