Camps
General Resources
Care.com Explore
A lot of local camps use Care.com explore to list their camps and have parents register for them. You can create a free account and search for options by the weeks you need, how old your kid is, and other factors.
Activity Hero
Activity Hero is a competitor of Care.com Explore above, so a lot of the camps that aren't listed there are listed here instead. Create an account here as well and search for options.
Koret Kids Camp
For those of you looking for a super convenient option, USF's Koret Health & Recreation Center offers a summer camp for kids 5-10 years old right on campus. I have heard there are some other sports camps that happen on campus too - check Sherri's spreadsheet above to see if they are listed.
