There are two new exciting experiences to be had at the Bronx Zoo, and both are part of the Treetop Adventure Program. One experience - called Climb - is an aerial adventure course consisting of rope bridges, rope walks, ladders, wobbly bridges and swinging elements. There are various levels of difficulty. The other adventure offered is Zipline, allowing guests to zip across the Bronx River 50 feet up in the air. Both adventures require a ticket in addition to an All Experience Ticket and there are participation requirements (some of which are: weighing between 50 and 75 pounds, and being able to reach 5’6” from flat feet). Check website for more information. Tickets are sold by time and appointment.
