In this week of Camp Fun we’ll be exploring the deep blue sea. For Under the Sea Week we’ll craft up seahorses and starfish and decorate picture frames with sea shells. We’ll watch sea creatures grow and make pretty ocean sticker scenes. Don’t miss our other adventure-filled weeks of summer camp craft ideas and activities that your kids can do at home!

You can never have too many coloring pages to keep campers busy during Camp Fun! Be sure to download our Under the Sea Free Coloring Page and set it out with colored pencils, crayons, or markers for a quiet indoor activity.
