Riggers Loft sits right on the edge of the San Francisco Bay. The historic building that once played a vital role in building the Liberty and Victory ships of World War II is now a working winery and cidery, with a tasting room and a stunning, panoramic view of the San Francisco skyline and beyond. https://riggersloftwine.com There is plenty of parking. While it is quite safe here, it's still a good idea to not leave any valuables in your car (and that goes for the Bay Area in general).
Travel from our place/Berkeley to Riggers Loft Winery (the wedding day venue) is about 20 minutes by car/Uber/Lyft. The cute town of Point Richmond is about 12-15 minutes away, but the road winds around a bit further to get to the venue.
Temps are usually pretty pleasant, though it can switch between sunny, foggy, or sometimes windy—so be sure to bring layers, maybe a hat, and your cool sunglasses.
