Want to plan a summer of fun for the little people in your life? Good news! An over-the-top summer doesn’t have to cost an arm and a leg or take tons of prep work. With this list of our ten favorite things to do with kids under 5, we prove the old axiom that the best things in life FREE (or at least very cheap).

4. Get Up-Close-and-Personal with the Pier 39 Sea Lions

For a real San Francisco adventure, take the kids to the end of Pier 39 to visit the Sea Lion Center where they can touch a sea lion pelt, view a real sea lion skeleton and learn all about these amazing creatures. Then step outside on the dock to get a view of the hundreds of sea lions that make their home on Pier 39. Take a spin on the carousel before you head home!
