Was just there two days ago. Was able to walk out to the fully exposed sandbar and was never deeper than my knees at about 10 in the morning, by 3 the water was waist deep at best. The "no swim" area is even shallower it appeared based on the fact that for most of the morning (tide came in about 3) more than 30 feet of what was clearly once under water was exposed. The lifeguards were relentless that you NOT even go close to the old water line over there, not sure what that reasoning was. Also of note, there were several groups of teenagers that they allowed on the beach, all with a tour of highschoolers from Brazil, the life guards did not enforce the rules for "adults only". The sea grass (and weeds) was a lot more than I have ever seen on 10 trips to Castaway AND the sea floor was more rocky than ever too, apparently there is a lot of sand erosion going on. First time in 10 cruises I was really disappointed with Serenity Bay. Ohh, but there was several conchs to see in the water, sand dollars, and a small shark in the area (the lifeguard chased him away)!
