The Hollywood Hike to End Homelessness @ Griffith Park, Boy Scout Trail
Mar 21 @ 8:00 am

Now that you’ve participated in the 2020 Greater Los Angeles Homeless Count, take the next step in helping address the homelessness crisis in Los Angeles County by joining the 3rd Annual Hollywood Hike to End Homelessness.
60,000 of our neighbors fall asleep unsheltered, alone, and isolated every single night in Los Angeles County. For many of our neighbors, challenges are layered. Mental and physical challenges, a fundamental lack of resources, and the social stigma of homelessness create an environment of indescribable loneliness, trauma, and pain many of us cannot begin to comprehend.
For the better part of a decade, The Center has provided a holistic and trauma-informed approach to ending isolation and homelessness. Offering unique Wellness, Health, Outreach & Housing, and Community Support Programs, they work every day to break down barriers to entry for our homeless neighbors. By doing so, we help build a path toward wellness and housing.
On March 21st, they will host the 3rd Annual Hike to End Homelessness to raise vital funds for The Center’s Community Wellness Program that serves thousands of vulnerable individuals living unhoused on the streets in our neighborhood. With these resources, together, they will give their participants access to community programming and connections to healthcare, mental healthcare, and housing.
This unique event is anything but the typical fundraising experience. Bringing together hundreds of Angelenos hiking in solidarity, this hike is a powerful display of our commitment toward ending homelessness in our community.
