Tualatin Ice Age Walking Trail
in Washington · centroid 10 mi from Portland
The Tualatin Ice Age Trail is a self-guided tour of sites representing the ancient history of our area. Along the trail, you’ll discover evidence of centuries-old ice, rock and bone, including the sites where a mastodon and ground sloth were unearthed. The trail also leads to a portion of the Tualatin ArtWalk, featuring sculptures, engravings and other Ice Age-inspired works of art.
There are seven self-guided tours for the Tualatin Ice Age Trail, where you can read and learn more on interpretive signs, as well as on the Tualatin Trails website. The Raging Waters Tour takes you back to the Ice Age floods that carried erratic boulders here and shaped the Tualatin River with landslides and deposits. The water-themed artwork at Tualatin Lake of the Commons is also a nod to that history.

Plan your hike
Maps + permits: long-distance trails like this often require permits for through-hiking, backcountry camping, or specific sections (especially in National Parks). Check with the maintaining organisation listed above and the relevant land manager before booking travel.
Water + supplies: water sources vary seasonally on most U.S. trails. Carry a filter and consult current trail-condition reports — through-hiker journals (PCT-L, AT Reddit, etc.) and the maintaining organisation publish regular updates.
When to go: hiking seasons vary widely with elevation, latitude, and snowpack. Through-hikers traditionally start the AT in March-April (Springer northbound) and the PCT in late April (Campo northbound). High-elevation western trails (CDT, JMT, Wonderland) generally aren't passable until July.
