Six of the “Greenest” National Forests

The National Forest System


St. Patrick's Day has us all thinking green. Our National Forests may not always look green but they're certainly doing 'green' things all year round. In honor of the holiday, we selected some of our National Forests where you're most likely to see green.

Olympic National Forest, Washington

Surrounding Olympic National Park, Olympic National Forest receives about 220 inches (more than 18 feet!) of precipitation every year.

We’ve Always Yearned for the Outdoors – Recounting Love in National Forests

I owe an immense amount of credit, gratitude, and inspiration to the absolutely amazing women of color that I climb, adventure, and discover with. Our public lands were not always public to black, indigenous, and people of color; and to this day BIPOC* are constantly breaking down barriers to ensure access, justice, and visibility for us all.
