HIGHLIGHTED EVENT:

HIKE FOR A CHANGE: 23 DAYS. 23 STORIES.

By Josh Moughan

Dirty Hands Project is thrilled to announce the return of Hike For a Change for its second year. From April 26th to May 31st, we will embark on a 230-mile journey along the Bay Circuit Trail, stretching from Duxbury to Plum Island.

This year’s theme, “23 Days. 23 Stories” highlights incredible stories of individuals and communities normalizing conversations around mental health and breaking the stigma that often surrounds it. Each day of the hike, Dirty Hands Project will feature a new story from Massachusetts and beyond, showcasing how mental health awareness and advocacy are creating hope and healing for many.

Hike For a Change is a powerful movement, and we are excited to have you join us for one, two, or all of the hikes.
