We made the hike on the Mistic Hanging Bridges Tour. We booked on the Viator website a daytour with the Arenal 1968 hike before lunch and the Hanging Bridges hike in the afternoon. This tour was done with Ecoterra, and our guide Francisco.
We were very happy about this decision and Francisco showed us e.g. a Mossy Mantis, a baby tarantula, a tiny blue jeans frog, a poisonous yellow snake on a leave below a Hanging Bridge,
a pair of tucans and together we spotted some other creatures. He was equipped with a professional camera and because of this he could take pictures even when dawn was coming up.
Finally he transferred his pictures on our cell phones and my wife and me were dropped off at our hotel. Pls make sure that all your important issues for a daytour will be covered by the agency and their tour operator.
All in all, we very very glad about our booking and we highly recommend the agency, the tour operator the their tour guide Francisco !
