As cases of COVID are rising again, on July 16, 2021 the Bay Area Public Health Departments for the:
Counties of Alameda, Contra Costa, Marin, San Francisco, San Mateo, Santa Clara, and Sonoma, plus the City of Berkeley jointly recommend that everyone wear a mask indoors in public places.
Not all masks are equally effective, as this video explains:
The CDC guidelines are greatly relaxed once someone is fully vaccinated (at least 2 weeks after last vaccination), but we may still need to take some precautions. See link above for the Bay Area recommendations on July 16, 2021.
On July 28, the CDC recommended that everyone, including fully vaccinated people, wear a mask indoors except for in their own households, when the 7-day case rate for the local area or nearby counties is 50 cases per 100,000 people or higher, or the COVID-19 test positivity rate is higher than 5%. This change reflects the much higher infection rates of the SARS-CoV-2 delta variant (as were the Bay Area recommendations of July 16).
With that exception, the guidance in these CDC links is still current:
Advice on getting together with other households is more complicated, depending on whether all adults have been vaccinated, and/or anyone is especially at risk.
COVID-19 is pandemic; people are infected all over the world. Travel was - and is - the main way this disease is spread from community to community, from my town to your town, and between countries. That regulation is still in effect as of June 2021.
As of January 29, 2021, the federal government requires everyone to wear a mask when using transit (including air travel).
While public transit is a necessity in the traffic-congested Bay Area, there's also concern about possible spread of the novel coronavirus on buses and trains. Routes may be changed during the pandemic, and policies may change - check the websites relevant for you frequently.
To slow the spread of the novel coronavirus in the United States, the Centers for Disease Control publishes updates, recommendations for travelers, and news about travel restrictions.
Be aware of the travel restrictions in place, both for the destination and for when you return home (may be required to quarantine when arrive).

Besides considering the risks of traveling to and from your destination, also investigate what's done at your lodging to limit exposure (ask about hotel or B&B cleaning practices) and calculate the risks of the kinds of activities you plan to include on the trip.
