Currents can be STRONG in some places. My suggestion is to wear a life jacket/snorkeling vest. I almost drowned several years ago in St. John because I was NOT wearing a vest. We went out on a scuba boat, with other snorkelers. I asked the guy for a life jacket since I am NOT a very good swimmer. Well long story short, I was snorkeling around, the waves were strong and when I looked up I was really far from the boat. I tried to swim back in but was getting battered big time. Then my arms got really tired, so I thought I would just try and float for awhile. In the end I panicked and HYPER VENTILATED! This was the first time in my life that this has happened to me. No joke, I seriously thought I was going to die. I started flailing my arms and fortunately someone saw me on the boat. The captain threw out the life saver but it was too far from me, and I started to go down. Scary!!! He swam out and got me. All this time my husband did'nt have a clue what was happening since he was scuba diving. Since then I learned my lesson.
