The Enoch Pratt Free Library begins its month-long Fairy Tale Festival (left) with a kickoff extravaganza Saturday and Sunday at the Central Branch, featuring magic shows, crafts, a giant knight (though I'm not sure I know what that means), and free pictures of the kids from 1 to 3 p.m. both days. If my limited experience with little girls is any indication (we have two boys), they won't need much incentive to don a princess costume. My guys, on the other had, do not have royal get-ups. Perhaps they will go as Sir Spiderman and the Earl of Batman...
On Saturday, there's a 5K run and Daffodil Festival at Cromwell Valley Park in Loch raven—which has a beautiful, majestic look of its own—featuring live music, face-painting, crafts, and, I presume, a large quantity of daffodils.
If you're ready to introduce your little people to the joys of fishing, the fishing rodeo at Patterson Park on Saturday is a great place to learn the craft, trying to catch some of the monster bass in Boat Lake. Bring your own rod and reel, or borrow on a limited supply there (no charge).
And of course, there are the perrenially great-for-kids activities, including the Walters, which, besides the great, often kid-friendly exhibits, has a fantastic play area on the lower level with lots of dress up stuff, puppets, puzzles, and an art room where there are facilitators to help you and are kids make great projects and bonus: FREE; The Baltimore Museum of Art frequently has great kids' activities; Also, the Marlyland Science Center ($3 off admission before noon on Saturdays, plus the weekly egg-drop contest), Port Discovery Children's Museum, The Zoo, two Storyville locations (we LOVE Storyville), The American Visionary Art Museum (also with kid-friendly exhibits, and the treehouse/sculpture out back if it's not too cold), the various nature centers and conservancies (Oregon Ridge, Irvine, Howard County), and—of course!— the Aquarium.
