Treehouse Island Zipline Adventures
A Pacific Northwest Paradise
Come to our fifty-acre island where you will
be enveloped by the immense trees and serene setting under the
shadow of Mount St. Helens.
The Zipline allows guests to traverse cables under
the canopy of majestic trees. You will be surrounded with
breathtaking views and natural surroundings; a feeling you’ll
find nowhere else! This course is a fun, family and group
adventure for those looking for a unique Northwest
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?
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

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