It was amazing!
My review is a bit late, but we traveled to CR in May 2015. Christian, Kennedy, and the other guide (name is escaping me at the moment) were great! They were very knowledgeable, safe, and kept the tour light-hearted and fun. We were a large group (10), with some very large guys (6’0″+, 300lbs+), and they were able to accommodate all of us. I have been fortunate to travel to a few different countries and this was definitely one of the best tours/excursions that I have participated in. Don’t hesitate, you will have a great experience!
