Among the shelf of books written about Portland's outdoors, one has become the standard reference for Forest Park: Forest Park: Exploring Portland's Natural Sanctuary by Marcy Cottrell Houle. If you have come across the title while planning a hike or looking for a gift, this reader's guide explains what the book is, who wrote it, and why it remains the definitive companion to the park more than three decades after it first appeared.
Who is Marcy Cottrell Houle?
Marcy Cottrell Houle is a wildlife biologist and award-winning author whose work is rooted in the Pacific Northwest. Her connection to Forest Park is not academic distance — she played a direct role in studying and advocating for the park during a pivotal period in its history. That combination of scientific training and on-the-ground involvement is what gives the book its authority. When Houle describes the ecology of the forest or the politics that nearly carved it up, she is writing as someone who was part of the story, not just an observer of it.
What the book actually covers
The book works on two levels at once. On one hand, it is a practical guide: it describes the park's major trails, helps readers understand the layout of the 5,200-acre forest, and orients newcomers to a place that can feel overwhelming. On the other hand, it is a work of natural and human history — the story of how a true wilderness came to survive inside a major American city, the wildlife that lives there, and the decades of advocacy that protected it.
Readers tend to come away with a different way of seeing the park. A walk on the Wildwood Trail or Leif Erikson Drive stops being just exercise and becomes a walk through a place with a hard-won past. If you want to pair that context with routes on the ground, our guide to the best Forest Park trails for every level maps the book's descriptions onto specific hikes.
Why it is still the definitive Forest Park book
Plenty of regional guidebooks list trails. Few combine that with credible science, real history, and a genuine sense of place. Houle's book endures because it does all three, and because its author helped shape the very thing she is writing about. For anyone who wants to understand why Forest Park matters — not just where the trails go — it remains the first recommendation.
Who should read it
- Newcomers to Portland who want to understand the city's wild backyard from day one.
- Regular hikers who already know the trails and want the deeper story behind them.
- Nature and history readers drawn to well-told accounts of conservation.
- Gift-givers looking for something lasting for the outdoors lover in their life.
The story behind the park's survival
One reason the book resonates is that Forest Park's existence was never inevitable. For decades the land along Portland's northwest ridge was eyed for development, logging, and roads, and it took sustained civic effort to assemble and protect the acreage we hike today. Houle's account brings that history to life, showing how citizen advocates, scientists, and city leaders pieced together one of the largest urban forests in the country. Reading it, you start to recognize the park not as a happy accident but as a deliberate gift from earlier generations — a perspective that tends to make every visit feel a little more meaningful.
What readers say they take away
The most common reaction from readers is a sharper eye on the trail. After the book, the birdsong, the old-growth survivors, and the creek crossings stop being background and become things you actively look for. Hikers report planning their outings around features the book describes, and newcomers say it gave them the confidence to venture beyond the first easy mile. It is the kind of book that changes how you use a place, not just how you think about it.
How to pair the book with a map
The guidebook is a wonderful read, but it is a companion to a map, not a replacement for one. The book gives you context and trail descriptions; a map gives you the precise, at-a-glance navigation you want under a canopy that blocks GPS. Many readers pair Houle's book with a waterproof pocket trail map for the field, or a topographic wall print for planning routes at home.

The simplest way to get both
Because the book and a map work so well together, the easiest choice for most people is the Explorer Bundle, which pairs Forest Park: Exploring Portland's Natural Sanctuary with a trail map at a better price than buying them separately. You get the full story and the practical navigation in one package — ideal for yourself or as a gift.
Where to buy
You can find Forest Park: Exploring Portland's Natural Sanctuary by Marcy Cottrell Houle on its own, or alongside the maps and bundle on our Forest Park collection page. However you explore the park, reading Houle first will change what you notice once you are on the trail.
