Will be staying at the Scuba Club Cozumel in July, and have the afternoons free. On my previous 4 trips to Cozumel, I've always had 3 dives a day with the packages. The package I have this trip only is for 2 morning dives, and will have the afternoons free, I've never seen the ruins guess this would be a good trip for that however I would rather go diving and would like to do some shore diving on the south east or north side of the island. I have heard it is can get pretty rough over on the other side of the island with the surf, however I do some cold water diving in Northern California, and know when too rough is too rough to get in, and have spent dive days watching the surf from the beach. Has anyone done this or can you please give us some tips?
