Hikes, beach trips, camping in the backyard or even in a large room in the house, picnics, park, library, check for free city events, games outside like tag, tv tag, hide and seek, cleaning up your yard and then going for a dollar frosty at Wendy's, coloring contest, bake cookies. Hope the list helps. I also have a hub about summer activities. Check out my profile! I'm sure those ideas can be adapted for spring! Good luck.
