I can't remember if the Ocean was mostly sandy, urchin free, or anything else one could step on. The last resort we were at had a lot of sea urchins in the shallow ends. I don't want to pack my watershoes if I don't have to!
We were at CN at the height of the hurricane season and the bottom was clean, sandy, and hosted a variety of small fish, star fish, but no urchins. I've heard that, if a storm deems it so, sea weed can be washed into Bloody Bay and litter the beach....until the Staff gets it clear. Maybe urchins with that, I don't know. But, it was sandy bottom our last trip.
Last year at Reno Bueno you really had to watch where you were walking. Sea Urchins and rocks everywhere! It was kinda creepy. The year before at CN I don't remember because my Mom was home hospice and the trip was non refundable because part of it was a voucher due to the norvirus outbreak at COR when we were there. I felt very guilty for going even though the Doctors, and everyone one said to go. So i wasn't paying much attention to stuff on that trip. I'm so looking forward to enjoying CN without any worry this time! Can't wait to sink my toes in that beautiful sand!!!
