San Francisco Waterfront Hike 10-17-2026

Bocce Ball Bonanza!

No walk today unless we want to do one late in the evening. It's Bocce Ball Bonanza! We will meet at the Bocce Courts at Joe DiMaggio Park in North Beach. 1 of our members has Bocce Ball equipment that they will bring, We may also try to get some Pétanque equipment. Bocce Ball is Italian in origin and Pétanque is the French version. So maybe we can have some friendly competition; Italy vs France! Please bring food and drink to share. Bring a cup or prepare to purchase one. I looked into reserving the Bocce courts, but can't figure out out how to do that, but the word is that no one is ever there in the evenings. So we should be good, but there are no guarantees. Also can anyone can bring camping lantern(s) because the courts are not lit. Hope to see you there! Please note: Phone help is not available for latecomers. If you are late it is very hard to catch up with us. We walk at a medium pace. Escorts or sweeps are not provided, so slower walkers should be completely prepared to finish the hike on their own if they become separated from the group, and they may want to consider bringing a friend to walk with them. I reserve the right to make small changes to the route as needed. Liability Disclaimer: The organizers of this meet-up are unpaid volunteers and not expert hiking guides. All participants agree to assume 100% responsibility for their own safety, conduct, and well-being and recognize that possible hazards exist while participating in outdoor (or any other) activities, and agree to participate solely at their own risk.

Hike Through The Presidio Before the Blue Angels Airshow (With picnic to follow)

October 10th is the Saturday of Fleet Week, and a great chance to see the air show featuring the United States Navy Blue Angels, the Air Force’s F-16, and Wingsuit Divers, and the Navy Parachute Team. City Steppers looking for a full day of fun can combine these events with one of my favorite San Francisco walks. The Presidio is a wonderful national park, smack dab in the middle of the city. Let's hike around the bluffs and the art, look for vistas and views, find some hills and stairways, and work up an appetite for the picnic to follow WE START WALKING AT 10:00 AM SHARP. We'll meet at the PRESIDIO FIRE STATION across from the Transit Center (restrooms) near the Main Post. Please arrive a few minutes early to check in and use the facilities. SPACE ON THIS WALK IS LIMITED, BUT THE PICNIC THAT FOLLOWS IS OPEN TO EVERYONE. We'll explore the areas around the Parade Ground and the outdoor Goldworthy installations (we may only be able to peek at the indoor one). We'll see the old and new Presidio, from its original boundary to the new Tunnel Tops. This is an easy to moderate walk, with a few small uphills and staircases. Most of the walk is along paths, but we go through some dirt sections and one short make-your-own-path hillside. The walk should take about 2 1/2 hours, depending on how much we dilly-dally. Dogs are always welcome on these walks. Presidio rules require they be on leash. After the walk we end up back at the Main Post just as the airshow begins. Bring a blanket or chair to sit on, and join the festivities. Just in time for lunch! There will be a separate announcement with info about this event. Before the hike, we can drop off our chairs and picnics with Rebecca who will keep an eye on them, so we will be able to enjoy our hike unencumbered. The air show starts at 12:00 Noon, with the Blue Angels flying between 3:00-4:00PM. We should be able to see most of the show from the Main Post Parade Grounds. There's always plenty to do before the big show. http://fleetweeksf.org/events/ GETTING THERE: MUNI Line #43 (Masonic) stops at the Transit Center. The next closest bus is Muni Line #45 (Union) which stops just outside the Presidio at Union and Lyon. Bus #28 (19th Avenue) takes you to Richardson/Lombard, and bus #30 (Stockton) goes to Chestnut and Divisadero just a few blocks from the Lombard Gate. Parking is plentiful, and although free parking can be difficult to find, we'll be early enough that you should be able to get parking at the Main Post for a reasonable fee. Even arriving early, this event will fill up fast. Give yourself plenty of time. The FREE Presidigo Downtown Shuttle arrives at the Main Post around 9:55 AM. his is probably the best option for BART users. EXPECT THIS SHUTTLE TO BE VERY BUSY, ESPECIALLY FOR THE RIDE BACK http://www.presidio.gov/transportation/presidigo/downtown-shuttle-schedule ATTENDANCE POLICY-- This group does not accommodate no-shows or crashers. Don't do it. City Steppers who no-show or late cancel can be removed from the group without warning. ALTHOUGH THIS IS A GREAT HIKE FOR DOGS. THE AIR SHOW CAN BE LOUD AND THE EVENT WILL BE CROWDED. SOME DOGS DO NOT HANDLE THIS WELL AT ALL. See our doggie guest rules. LIABILITY & SAFETY-- You are responsible for your own safety on all City Steps walks. Your yes RSVP confirms that you have read and agree tothe liabilty policy that can be found at the bottom of every Meetup page. WHAT TO BRING: Dress for the weather and wear comfortable shoes. Water- there are a couple of places you can refill along the route A picnic lunch and a blanket or lawn chair of you have one. Rebecca will stay with it while you hike. Your camera for the views and binoculars for the show.

Sunday Kickball @ Bushrod Park!

BASS presents our favorite event, kickball! We will be at our normal spot in the East Bay at Bushrod Park in Oakland! Bring your soccer cleats (for better grip on the field), sunscreen, and athletic wear and water for a fun time out! For those who haven't played kickball before, the rules will be explained and demonstrated before we start. Depending on the attendance, we'll either have 2 teams facing off or a rotation of 3 teams all together. Then after we may hit the local pizza/bar scene if everyone still wants to hang out. We have a HARD START at 1pm, so please be sure to show up on time for warmups! (We also nearly lost the field previously because not enough people were there on time) See you there soon! 🔴 Note: Please, please, please don’t no show. 🙏 It makes these events really difficult to plan. If you no show once, you will be given lower priority for future events. The second time, you will be removed from the event list for any attendee limited event we host.

We will meet at the Rock Springs trailhead, and walk a there-and-back-again trail to meet some of the charismatic lichens of the area. These grow on rocks, trees, and on the ground. Participants will get to know certain lichen species, as well as lichen growth forms, and lichen ecology. The hike will be easy to moderate, with frequent stops to look at lichens. Bring a magnifying glass or hand lens if you have one - lichens are even more fascinating up close! Dr. Klara Scharnagl is the Tucker Curator of Lichenology at the UC Berkeley Herbarium. She is continually fascinated by the lichen symbiosis, and the many forms that lichens take. Her emphasis is on lichen ecology; how lichens respond to and interact with their environments.

FleetWeek, AirShow aboard the cutter Cetacea on Sat, Oct 10!

The cutter Cetacea (latin, marine mammal-dolphins/whales), a beautiful, strong, and well-appointed 42' blue-water sailboat with extensive operational and safety systems, invites a few crew aboard with a highly experienced skipper and platonic-only water sports enthusiast and science/technology entrepreneur. Strong preference for adventurous crew, as can be seen in the various photo albums of crew on more than 140 no-cost personal sailing adventures the past 9 years! This event is for women that prefer to sail with other women; sorry guys but there is a big demand for female-only sailing that isn't being met. Sailing experience isn't necessary, but enthusiasm for a fun, safe and exhilarating daysail, is! Yayyy,,, the **USAF Blue Angels** are back!!!! We'll slow-sail around the North Bay while gawking at **[big ships](https://fleetweeksf.org/events/parade-of-ships/)** and then hover near the flight zone for 3 hours of exciting flybys! You can view the Official **2026 FleetWeek** ship and Airshow info **[here](https://fleetweeksf.org/air-show/)**. This is an adrenalized fighter-jock sightseeing show, not a substantial sailing experience, and so we'll have a larger crew (6-10) than normal with a lot of sitting, eating, drinking, photographing, and ogling the aerial displays! If calm waters then we'll rig the Spinnaker swing! Please join the waitlist and experienced Shetaceans have priority for this **[event](https://fleetweeksf.org/air-show/)**. Please note that parking is very limited at the marina and you'll probably have to park at Pier 34 and walk the short distance (1/4 mi?) to SouthBeach marina. I'll send an agenda with clothing/food/parking/other info to our crew by Mon, Oct 5. Please be sure to rapidly respond to my emails to you, via your meetup account, or you will be summarily scuttled in the "Not Going" zone of abandoned flotsam, jetsam, and tidal detritus :-0

Sponsored by Friends of Mt. Tam in Partnership with California State Parks Mt. Tam has many microclimates, and its location near the convergence of several different ecoregions (North Coast, South Coast, Central Valley) supports a wide diversity of plant communities. Rock Springs is a great place to explore mixed evergreen forests, grasslands, riparian forests, and serpentine barrens. We’ll meander through these plant communities, discussing and identifying some of the plants and ecological processes that characterize them. Our walk may cover up to 1.5 miles, and you might want hiking poles for several short rocky/steep/off trail sections. David Edelson is an amateur naturalist. He retired from a career focused on environmental advocacy and land conservation, most recently with The Nature Conservancy. He has led field trips for local chapters of the California Native Plant Society as well as Marin Audubon Society and Golden Gate Bird Alliance.
