The northern section of this Portland City park borders on the Oregon Health Sciences University Campus off of Sam Jackson Parkway and Terwilliger Boulevard and encompasses two ravines on the slopes of Marquam Hill. In addition, a large swath of steep hillside in the southern Sentinel Hill sector of Marquam Nature Park remained undeveloped over the decades, except for the through route of the Marquam Trail, and was criss-crossed by a network of user paths that often contributed to erosion. As of 2014, an official new trail network has been in place, allowing for an up and down loop from either the Marquam Nature Park Shelter Trailhead or the Marquam Trailhead on Terwilliger Boulevard.

Activity Notes

This amazing little hike starts at the Marquam Shelter off Sam Jackson Road below OHSU.  We will meet at the parking lot.  Well behaved dogs are welcome, but you don't need a dog to attend.  We will walk up the Sunnyside Trail and then follow the Marquam Trail over to Marquam Hill Road.  We will cross the road and then travel through a new set of trails that go below Fairmount and end up near Terwilliger.  We will backtrack on the Marquam Trail back to the Marquam Shelter.  5 miles. 600ft elevation gain.
