The average water temp was 75 degrees F. We brought our own long-sleeved shorty 3mm wetsuits and skins. They were perfect. The water temperature might be different in Oct-Nov as I think that is the beginning of the warm-wet season. The snorkeling gear they had on board was of good quality and in good shape. But if you have big feet like my son, you might want to bring your own fins. Someone recommended we bring our own mask & snorkel and that made sense, but most of us found their masks to be just fine and didn't unpack our own.

They had snorkeling excursions scheduled every day and we took advantage of every opportunity to get in the water. We saw sea lions every where we went, in the water and out. Marine iguanas, sea turtles, white tips and big rays were plentiful and we saw a handful of penguins.

Us guys went diving with Scuba Iguana on two half-day trips and got to see some hammerheads, lots of white-tip sharks, a few black tip sharks and one Galapagos shark. Got my shark fix for a while. <img src="http://www.traveltalkonline.com/forums/images/graemlins/Wink.gif" alt="" />
