Confirmed from Marys River Natural Area'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.
Quaint local parkland known for its verdant terrain, green expanses, walking trails & boardwalk.
What runners say about Marys River Natural Area
“A beautiful natural area with one of the last surviving vernal pool (pools that dry up in the summer) wetlands in the Willamette Valley.”
“Absolutely peaceful and beautiful area for a nature walk!”
This is a lovely place for a walk. If you park near the east entrance there is a gravel parking lot and short road to bring you closer to the trail head. Because of the flooding, that parking lot and road are very washed out and inaccessible.
A beautiful natural area with one of the last surviving vernal pool (pools that dry up in the summer) wetlands in the Willamette Valley. Every couple years there is a large bloom of a very rare native monkey flower which only exists in this ecosystem.
This has been my favorite place to jog for years! Especially in the rain and fog!! 🥰 Something really majestic about the smokey grey mountains and trees in the distance across the large open fields!
Absolutely peaceful and beautiful area for a nature walk! There's pretty flowers, frogs, little garden snakes and you can have a stroller if necessary with no struggle.

“Its a nice short little walk, wish it was a loop, but given all the hurdles that had to be overcome to build the existing walkway, I'm happy that it's there at all.”
