I will be in Coron for four days in February, flying into Busuanga late morning on a Monday, flying out early afternoon on a Thursday, staying in Coron town. I'm planning to scuba dive some of the wrecks on the Tuesday and join an organized Coron Island day trip on the Wednesday. My question is are there any partial day tours or can you get a boat ride to go snorkeling for a couple hours on Monday afternoon or early Thursday morning? I see that Siete Pecados is a well-reviewed snorkeling site close by and, depending on which island day tour I end up with, I might not see on the full-day tour. I will probably make a trip up Mt. Tapyas while I'm there also, but would like to sneak in a little bit more snorkeling on one of the travel days. Thanks.
