Little Folks camp in Georgetown!
They have art, cooking, access to a pool, creative water play, themed weeks, sports, and a moon bounce. So much more. My kids absolutely loved the Little Folks camp in Georgetown last year:
With a morning only and full day option, and this year they are incorporating a community service aspect in which the camp is partnering with a low income elderly community in Foggy Bottom.
Mostly pre school age kids but it is a wonderful camp in a great DC location with awesome staff!
