As of last month, The Maritime Museum became one of the first National Park Service sites to offer free WiFi. Use it now in the library or museum and expect it soon in the outdoor lagoon, Aquatic Park, Muni Pier and historic ships.

Late last year, San Francisco went live with a free WiFi network along the entire stretch of Market from the rainbow flag in the Castro to the Embarcadero. This is just the start of the city’s plan to roll out a free network across the city.

The main branch of the public library has natural light, stunning architecture and lots of outlets to use. However, watch out for slow connections and messy bathrooms.

The Internet is fast and the outlets plentiful in this combo café/workspace. Either hang out in the lounge and patio for free or pay $2/hour for additional features like widescreen monitors and printing.

San Francisco’s first-ever Whole Foods offers free Wi-Fi in its small downstairs café. Other Whole Foods outlets around the city, like the one in Potrero Hill, have started charging for WiFi unless you make a purchase.

Get some culture, or at least some fantastic food from the museum café, while you work. Museum entry is $12, but you can enter the café for free.

Okay, this is really just part of the Market Street WiFi network, but this is probably the best place to use it. Accompany your work with Blue Bottle and fresh farmer’s market produce.

This private library isn't exactly free - it costs $100 per year to join, but it's worth the entry if you're serious about getting some real work done.
