We rented snorkeling gear on our last full day and got what we needed. There were three options of gear to choose from and we chose the most expensive one, which was still very reasonable. Black rock was the recommended place to go. We found free parking by the wharf and just walked on the beach to Black Rock. My husband ended up having problems with his mask, but stuck with it anyway because we didn't have time to go back and get another. When we returned the gear, we told the person and he said thanks they will fix it. So make sure you try on the mask, everything fits ok and tightens okay before you leave!
