Bay Day Trail Challenge

The Bay is a place for everyone and a vibrant source of fun and adventure, ready to be explored.

From October 1 – 31, we invite you to connect, explore, and discover the San Francisco Bay Trail and help celebrate the 5th Annual Bay Day.  You can enjoy the outdoors and #RecreateResponsibly during the pandemic to maintain your physical and mental well-being.

There are two ways you can participate in the Bay Day Trail Challenge. Choose the one that works best for you and yours.


Connect directly with the Bay and take on the 25-Mile challenge. You have a full month to explore and choose when and where you want to go. With over 350 miles of trail you can safely walk, bike, run, wheel, or paddle while maintaining six feet of distance. The San Francisco Bay Trail connects communities to parks, open spaces, and to each other. You can walk or bike the Embarcadero for an urban adventure, head to Point Isabel Regional Shoreline for a dog-friendly oasis, or discover a waterway of wetland wonders from Bedwell Bayfront Park to Alviso. There are so many options to choose from!


Participate in FIVE activities on the trail or in your neighborhood. We understand that not everyone can make it to the Bay Trail or may not be comfortable going out during COVID-19. For this challenge, you can discover the Bay wherever you are. Whether it’s kite flying, bird-watching, picnicking, or connecting with local culture through Bay Trail art or history-filled audio tours, there are so many ways to explore. Check out this list of ideas from our friends at San Francisco Bay Trail, look for weekly inspiration in the What’s New section, and follow us @saveSFbay for updates and activities.

Six potential ways to explore the Bay this Bay Day


As you explore the 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.
