What is Ziplining?

A zipline tour allows guests to fly through the trees on 6 different cables. Participants will also maneuver up ladders and over bridges to the next zipline take off deck. The longest cable line is 600 feet and our tallest zip line is 75 ft. in the air! Our course is a fun adventure and safety is our top priority! The cables and trolley system allow people to ride on a harness, travel great distances and heights soaring from tree to tree. The state of the art course has been thoroughly inspected. Our guides are extensively trained and guests wear harnesses, helmets & gloves while ziplining.

When does Ziplining operate?

Tours typically run at 10am and 1pm.  Times can be flexible and we add tours as these fill up so be sure to call us if you cannot book what you want online.

Do I need a reservation? If yes, how early do I have to book?

Yes! Reservations are required to make sure our staff is in place and the boats are ready to whisk you off to our island paradise. Spots are filled on a first-come, first-served basis. This means that sometimes you can call the day before and get a spot, and other times, our calendar is very booked and calling weeks ahead would be necessary! So, if you have your heart set on a certain day/time or if you have a large group, the earlier you call, the more likely you will get your choice spot! But if you want to go the same day or the next day, don't hesitate to call, there just might be availability! Reservations are held with a credit card.

How long does it take?

A tour takes between 2 1/2 – 3 hours depending on how large your group is. This time frame includes the time needed for check-in, your boat ride to and from the island, and your zipline tour.

What does it cost?

Can anyone Zipline? What are the physical requirements?

  • Weight minimum is 65lbs. and maximum is 250lbs (participants will be weighed discreetly prior to the tour).

  • Height minimum is 4'6". No maximum height.

  • Minimum age is 9. Children under 18 must be accompanied by an adult.  Anyone under 18 must have a waiver signed by a legal guardian.  The adult can be on the zipline tour or on the island with an island only pass.

  • Due to the nature of the tour, guests must be in reasonably good health.

  • Activities will require moderate physical exertion, including walking across rope bridges and climbing up ladders.

People with the following conditions can NOT participate in the Zipline Tour:

  • Pregnant women (women in first trimester pregnancy may participate with written physician approval)
    People with heart conditions

  • People who are unable to walk up steps

  • Intoxicated individuals

All guests will be required to sign a release waiver before participation. Treehouse Island employees have the right to exclude anyone from participation for medical, safety, or any other reason.

What should I wear or bring?

You will be out in a camp type setting. Wear comfortable attire that you’re not afraid to get a little dirty! Here are a few things we suggest:

  • Close toed shoes are required (tennis shoes are great); you will not be able to participate in flip flops or open toed shoes.

  • Gloves are available, but you may bring your own if desired.

  • Harnesses go on the upper leg, so most people are most comfortable in longer shorts that are not overly baggy. You can also wear knee or full length pants if you prefer.

  • Optional items to bring: water bottle, sun block, sunglasses, beach towels, etc. Since you can't carry any items while zipping, there are small lockers available if you need them.

  • Do not bring your valuables; Treehouse Island employees are not responsible for lost or stolen items.

  • Do not bring bug repellent with deet. Deet melts nylon, which our harnesses are made out of. Deet-free bug repellent will be available for purchase in our reservations office.

  • Most importantly, bring your positive attitude, ready to have some fun!! Curmudgeons will be returned to the mainland.

Safety is our first priority! Zipline guides have been extensively trained and our course has been inspected and cleared by experts in the zipline industry. The course and equipment are thoroughly inspected on a daily basis. Guests are attached to cables/ropes the entire time they are in the trees. Participants will ALWAYS be attached to the safety system throughout the entire course until they are safely on the ground after the final zipline.

Water is available on the island. There are no concessions available.

Are there bathrooms?
Yes. Though we are in a remote setting, there are facilities available on the island.

What if it rains?
We zip rain or shine.

Do I do this myself? How do I land at the next platform?
The tours are fully staffed with friendly experts. All ziplines are equipped with a braking system and a tour guide will be waiting for you to help you land and send you off onto the next platform.
