100 Hours Outside

Let’s get happier & healthier together! 

Research shows that being outside and experiencing nature can improve our mental health and increase our ability to focus. ACCPF’s 100 Hours Outside Challenge is a summer challenge designed to help us disconnect from our devices & reconnect with nature and the outdoors. During the course of the 45-day challenge, we encourage participants to explore new activities and develop healthy & sustainable outdoor recreation habits by tracking their daily outdoor activities.  

Challenge yourself to get outside by making daily habit changes like eating lunch outside, taking a morning or nightly walk, reading a book outside, backyard gardening in addition to dozens of traditional summer outdoor fitness & recreation activities! Download the flyer HERE.

How do you get your 100 Hours Outside?


Staff Favorites 

Andrea – Bartholomew Park   Located in Sonoma and perfect for a short hike, a picnic & wine tasting too! Dog friendly & adjacent to  Bartholomew Estate Winery
Joy – Doran Beach Only an hour and a half away, but it feels like another world. This family- and dog-friendly beach has great walking trails and even better outdoor dining options right on Bodega Bay. As an extra bonus, you can stop for amazing ice cream at Sweet Scoops in Sonoma!
Janelle – Mt. Tamalpais Mount Tam has amazing trails.  I love to hike to the top and take in the magical ocean views.
Tammy – Lake Hennesy There are so many wonderful places to birdwatch, but if I had to pick, it would be Lake Hennesy, the Conn Creek side, because it’s always so peaceful there.
Patricia – Matt Davis Loop I love to go on road trips with our airstream, hiking, and fishing all over California.  Closer to home, my family loves the Matt Davis – Steep Ravine Loop to Stinson Beach and the Cataract Falls trail on Mount Tam.
