Challenge Inspiration

Six potential ways to explore the Bay this Bay Day


As you explore the San Francisco Bay Trail, please follow these guidelines to ensure a safe, healthy, and inclusive trail experience for all.

  • Know before you go: Check the status of the place you want to visit. If it is closed, don’t go. If it’s crowded, have a backup plan.
  • Practice physical distancing: Keep your group size small. Be prepared to cover your nose and mouth and give others space. If you don’t feel well, stay home.
  • Plan ahead: Prepare for facilities to be closed, pack lunch, and bring essentials like hand sanitizer and a face covering.
  • Explore locally: Limit long-distance travel and make use of local parks, trails, and public spaces. Be mindful of your impact on the communities you visit.
  • Leave no trace: Respect public lands and waters, as well as Native and local communities. Take all your garbage with you.
  • Build an inclusive outdoors: Be an active part of making the outdoors safe and welcoming for all identities and abilities.
