I would love to get some input from travelers who have gone on Cano Island snorkeling or diving tours. We will be on the Pacific coast in one week! Thank you

Note that Cano Island Preserve is supposed to be closed at least through mid-May, possible longer; there are still tours running for water-only activities, though. http://www.travelexcellence.com/news...ogical-reserve
We took a snorkeling tour out of Sierpe (it left from the Las Vegas restaurant; you can google and find lots of links). It was a long ride to Cano, first through the mangroves, then the open ocean; they didn't pause or point out anything along the way, in order to get to the island and snorkeling (which was just ok, although that's certainly one of the better Costa Rica snorkel spots). The cost was ~$75 pp, all equipment and lunch (sandwiches, chips, juice) provided. The ride back was more leisurely; we paused to watch a very late season whale and baby, then saw snakes, birds, and monkeys and learned about the mangroves on the way back.
I thought it was an enjoyable day; the snorkeling was ok, was a bit bored by the time spent on the beach at Cano (you might not even be able to land), and really liked the mangrove part on the way back.
You can also take day-hike trips from the same place (Las Vegas restaurant in Sierpe) into Corcavado NP (also includes a bit of the mangrove ride) for about the same price.
Sierpe is easily accessible from the Uvita area.

Snorkeling is amazing , Cano Island is really beautiful, Do not forget get a snorkeling tour .

Noted: "james" is very enthusiastic about his country.
However, the truth is that snorkeling compared to other places is only so-so (even turbid near Cano, depending on the waves), and Cano may be closed to boat landings when you are there. Be sure to check, unless you only want the boat trip and not the landing/beach sitting on Cano.

My father went on the snorkeling tour and was disappointed. He said that the water was not very clear and that he wished that he had come on the mangrove tour down the Sierpe river with us instead. Also a couple that went on the diving trip were also terribly disappointed. I am glad that we opted for the mangrove knowing that. It's amazing how much you can see from a boat! Monkeys, macaws, snakes, bats, birds of all sorts, caymans, JC lizards, JC birds, Crocs .....

Thank you for the info!
