Treehouse Island Zip Line Adventure

Specialties

Guests enjoy a scenic boat ride to and from Treehouse Island. The boat ride wows visitors with spectacular views of Mt St. Helens and Mt. Rainier. Upon arrival on the island, guests are greeted warmly by a guide who fits them into their harness. Then off they go on an adventure through the trees! They ride six different zip lines ranging from 100 to 600 feet long (that’s two football fields long!!) and 75 feet high. The tour lasts about 2 ½−3 hours. Some guests choose to come to the island on «Island Only Passes» to enjoy the grassy park and fire pit area since they prefer to enjoy the zip lines from the ground, taking photos of their friends and family zipping by overhead!

Some of the most fun has been with organized groups such as churches, scouts, businesses, schools and teams of up to 60 who come for the day or overnight camping. Groups not only receive discounted prices, but more perks on the island as they roast marshmallows and bond around the fire pit, play games or picnic in the grassy park, and of course… zip line!

History

Established in 2013.

A zip line park was not the first thing in mind for Treehouse Island, a 50 acre island in the middle of Silver Lake, WA in 2008. Instead, Grady and Jim dreamt of building unique treehouses, but as fate would have it, their dreams of tree houses were caught in the complicated web of regulation.

In late 2009 a new dream sprouted, and Grady and Jim started building a zip line park. The building of the park itself was an exciting challenge since both men are builders, artists and businessmen by trade. As for the zip line park, you’d be correct if you were thinking that this project would be laden with complicated regulations as well. But the good news is that they stayed with it; and perseverance paid off! They were thrilled when the zip line park opened in September of 2013.

Now, we have a great time zipping, picnicking and camping with local people as well as visitors from all over the world. Contact us to join in the fun!
