Confirmed from Boulder River Trail's own listing, the park or land manager's website, and runner reviews. Blank cells mean we could not verify that fact — we would rather say "not reported" than invent one. There is no Easy / Moderate / Hard rating on this page on purpose: a one-word difficulty score tells you nothing about whether a trail suits your run. Surface, distance, shade and hours do.

🏞️ beautiful scenery 13 mentions

“As for the falls itself, it's one of the most unique and beautiful you will find around here since it comes in parallel to the river.”

👟 good for all levels 6 mentions

“Incredibly family friendly, especially if only going to the first waterfall (about 1 mile in).”

Says it's 7 miles round trip, but there is nothing to see beyond the second set of falls. Just go to the second set of falls and turn around. Lots of fun features like bridge's and cut out logs. Falls are gorgeous.

This is one of my favorite places, well worth the drive. It's a fairly easy hike, with lots of beautiful sights along the way in any season. Note1: It will be hard to maintain a social distance at many points on the trail.

★★★★★ — Rheanna , Sep 2020

Wonderful trail, no snow in December so good for a winter hike. The trail is deep enough in the mountains to feel like you are hiking in the cascades, but low enough elevation to keep it mostly snow free and "easy" to access. The road leading to the trail head has a lot of pot holes, watch out and go slow driving up!

Trail conditions & character

What this trail is actually like underfoot and overhead, taken from its own listing and from reviews. Each one links to every other trail with the same character. Busy or quiet is reported as a plain fact, not a plus or a minus — a runner heading out alone at dawn often wants company on the path, and someone running intervals wants an empty one.

“Waterfalls, the river, and all the moss and lichen hanging from the trees makes for a fantastic PNW adventure for hikers, backpackers and families alike!”
