A city that grew up in a forest
Most cities plant trees. Portland, more accurately, was built in and around them. Drive in from almost any direction and the skyline you notice first is the dark wall of Douglas fir on the West Hills, and within the city limits sit some of the most remarkable tree parks in the country. They are worth visiting in their own right, and they also happen to be the best free education a homeowner can get about the trees already standing in their yard.
Here are three of our favorites, from a small volcano in the southeast to a genuine wilderness on the city's northwest edge.
Mt. Tabor: a park on a volcano
Southeast Portland's Mt. Tabor is built on an extinct volcanic cinder cone, one of only a handful of city parks in the entire country that can make that claim. You would never guess it from the leafy neighborhood at its base, but the hill you are climbing is the real thing.
A short walk past its historic open-air reservoirs, which are landmarks in their own right, takes you up through stands of big Douglas fir and maple to a clearing with a genuine, sweeping view back over the city. It is the fastest way in town to feel like you have left the city without actually leaving it, and on a clear evening, with the light going gold behind the West Hills, the view is hard to beat. Joggers, dog walkers, and families treat it as a shared backyard, and it shows.
Hoyt Arboretum: a living tree catalog
Up in the West Hills above downtown, Hoyt Arboretum is a curated collection of thousands of trees gathered from around the world, laced with about twelve miles of trails and anchored by a visitor center and gift shop that are open daily. It is beautiful enough that people hold weddings on its grounds, and quiet enough that you can lose an afternoon there without trying.
For a homeowner, though, its real value is as a living catalog. Walking the trails, you can see exactly how dozens of different species grow in our specific climate, at full mature size, before you ever commit one to your own yard. Wondering how big that dogwood really gets, or whether a particular conifer stays tidy or sprawls? It is probably growing here, fully grown, with a label on it. It is the best free planting research in the city, and it will save you from the classic mistake of putting a future giant three feet from the house.
On a scale of ten, the park ranger said, Forest Park is a twenty. Some of its trees stood here before the city existed.
Forest Park: an actual wilderness inside the city
Forest Park is the giant of the three, and one of the largest urban forests anywhere in the United States. At roughly 5,200 acres threaded with 75 to 80 miles of trails, it is a true refuge for hundreds of species of animals and plants, and yet its trailheads sit only about fifteen minutes from downtown. You can step off a city street and, within minutes, be standing somewhere that feels genuinely wild.
Its longtime ranger, Bob McCoy, describes it as a tremendous healing place, and the trees back him up. Some are well over 300 years old, with a few likely approaching 500, meaning they were already old when Portland was founded around them. The author Marcy Cottrell Houle spent three decades studying the park and gathered all of it into her book Forest Park: Exploring Portland's Natural Sanctuary. Spend a single afternoon on the Wildwood Trail under those old firs and you understand, in your body and not just on paper, why this city takes its trees as seriously as it does.
What these parks say about your yard
Walk any of the three and the same truth comes through. Portland is, at heart, a forest with a city grown into it, and the line between the wild trees and the yard trees is thinner than it looks. The towering conifers and broad big-leaf maples shading the trails at Mt. Tabor and Forest Park are the very same species standing in our yards, shading our driveways, and dropping cones on our roofs.
That shared heritage is a gift, and occasionally a responsibility. The same trees that make the parks magnificent will, on a residential lot, lift sidewalks, drop heavy limbs in an ice storm, and sometimes simply outgrow the space they were planted in. That is why understanding how tree roots behave around driveways and patios matters as much for a homeowner as it does for a park ranger, and why getting the timing of any tree work right for our seasons makes the whole job easier. Love the big trees, and manage the ones in your own yard with eyes open.
Those same big firs and maples are the trees in our yards, and when one finally has to come down, grinding the stump below grade is how you close the chapter cleanly and get your space back.
