Join an outdoors play group. The new site Forest School For All is a resource for anyone looking for an outdoors play group. If there's not a group in your area consider starting one - details are on the Forest School For All website. You can also find groups for all of your interests at Meetup or just get some friends together and start your own adventures.
Visit a National Park. There are so many amazing places in the United States and Canada. Why not plan a family vacation to experience them? Our favorites include Yellowstone, Denali and Arches National Parks. But if those are too far away why not try your State Parks? Several have great day trip locations including lakes, forests and wild spaces.
What are your summertime plans? How will your kids be entertained and involved?
