I see that Cano Negro is a highly recommended tour especially on this site. We are on the fence about doing it or not. It seems like a really long day and I am just not sure if it's worth it for us. Here's a brief overview of what we will be doing while in Arenal. We are staying at Lost Iguana for 4 nights. It's for our honeymoon, so we want some adventrue but also some relaxing. While there we want to visit the hanging bridges, ecotermales and do the sky trek zipline. We will also have a couple's massage at Lost Iguana's Spa. So I guess I want to hear people's recommendations about whether or not we should add Cano Negro. Is it going to be too much hustle and bustle? What are the highlight's of this adventure?
