Easy and fun. There was a concise explanation at the beginning of how the zip lines worked. The staff did all the hooking/unhooking of lines. Not much to remember except to lean back and enjoy the view as you zip line.
Be patient as you wait for the last zip-liner to complete the line. It may be sunny, cloudy, breezy, warm depending on the time of year. March is an excellent month to visit Puerto Rico and to do zip lining.
After zip lining, our guide walked with us to the swimming location. Along the way, he provided information about the floral and fauna and animal life. There were opportunities to jump off the platform into the water, rope swing, walking along the shore, hanging out, etc. The water was refreshing.
After we finished the walk/swimming, we were driven to the beach and had lunch. There were many food stalls/restaurants ranging from Puerto Rican dishes to pizza, to seafood/steaks, to burgers. Travelers can choose to eat lunch, visit gift shops, and go on the beach. It was a nice ending to the excursion.
