For those of you looking for more learning opportunities this summer--something we never object to--SF Kids has a list of summer camps and programs, including many that are low cost or free. We also offer opportunities for summer school and internships for high school students.
Bay Area Kid Fun's constantly updated compilation of family-friendly events is a great reminder that San Francisco itself is one of the best classrooms around. If you have a library card, you can also check out a Family Pass for a day of free admission to local attractions and pools.
