From what I have read, you hop into a small speedboat with room for two people and follow a tour guide through the lagoon. The tour takes you through winding mangrove paths before eventually heading out toward the Caribbean Sea.
Along the way you get to cruise through the water while taking in the scenery, which already sounds like a great adventure.
The tour also includes a stop at a snorkeling spot where the water is full of sea life. It sounds like a fun way to experience both the jungle waterways and the ocean in the same trip.
For now, it is just another exciting activity to add to our growing list of things we might want to do while we are there.
