Go play outside (Mom was right)

Earth Day is April 22, so tip your hat to Mother Earth by listening to what moms have been saying for years.

hike, bike and volunteer outside

Why Mom was right

Getting outside is good for you: as little as 15 minutes in the woods has been shown to reduce levels of cortisol, the stress hormone.

And why not volunteer to make your community a better place while you’re at it? Portland is filled with outdoor volunteer opportunities. Consider inviting friends to join you, or make new ones.

How it benefits you

Getting outside, spending time with friends, and volunteering your time to help others have all been shown to make us happier and healthier.

Where to go play

Portland is home to more than 152 miles of regional trails laced together, connecting people to each other and to the natural beauty of our city. And right at the heart of Portland is Forest Park, one of the country's largest urban forest reserves — which is eight miles long and covers 5,200 acres!


Sign up to pull ivy in Forest Park or plant trees around Portland. Lend a hand to restore the Willamette, or clean up the beach and other natural areas. We live in a beautiful place, so get out and enjoy it!
