My wife and I went on the Mangrove Eco-tour. Our guide, Daniel, had everything set up for us when we arrived at the scheduled time. He gave us a brief overview of paddling and safety on the kayak, and then we were off. While paddling Daniel informed us of the history of the area. When we'd come across the native wildlife he'd give us details about the animals, including the elusive Mangrove Monkey. Throughout the trip he was taking pictures and within a day Daniel sent us the pictures which are great memories.
I'd recommend this trip to just about any one except absolute kayaking beginners. I have some paddling experience, and got hung up a couple of times due to my lack of attention.
Overall, it was a great and unique experience!
