    Leader: Seth Feinberg

    TO ALL SIERRA SINGLES PARTICIPANTS: We are a volunteer organization and depend upon your generosity with your time. Consider becoming a leader! To continue offering the frequency and variety of hikes that you find in our schedule, we need to recruit new hike leaders. It’s not hard to become a leader, and it’s fun and rewarding to lead. You’ll be able to share with others the hikes that you love most. If you think you may enjoy it, but aren’t sure, consider co-leading a hike with Albert, Seth, or any of our leaders.  To learn how, contact Albert Chiu or Seth Feinberg, or speak to any leader.

      I messaged you yesterday but you might have missed it, but as Richard and I are both based in SF I'll be carpooling with him for today's hike.

    Thank you for responding to my question about the designation for canine hikes, which I see this one isn't. I will release my spot to another hiker; and hope to join you all on a future hike!


  • Richard

    If anyone needs a ride from SF, I will be at Glen Park BART 9:30-9:35am


  • Dana

    Know whether I can bring my bernese mountain dog on this hike?

      The policy of the Sierra Club is that unless a hike has been designated as a canine hike, dogs are not permitted. This one has not been designated as a canine hike.
