yes, most areas in los cabos area are dangerous. Not sure why @WisestIowan would say cabo is 'way' better than Riviera May. I have been to both and would say the opposite. Unless you are into MTV's old spring break beach shows (ie-- you are a teenager).In Riviera Maya you are correct. Especially at the Valentin. In Cabo stay out of the water. It’s black flags there. Unless you are on Medano Beach or one of the little coves it’s incredibly dangerous.
