I been on most of the beaches from Cancun to Xcalac and Akumal has the nicest because it is in a cove with a jetty on the north end. The water is totally clear too. The only other beach to rival Akumal is the State Park beach on St George Island, FL. I stay in Tulum every year and I always visit Akumal because I like the beach.
