The Effie Yeaw Nature Area is one of Sacramento's best well-known secrets. I call it that because people don't realize the treasure that is tucked in that little corner of Carmichael. It is astounding what you will find if you visit there often enough - deer, coyote, lizards, raptors, turkeys, not to mention all of the diverse plants that are present there. Nowadays, I am not surprised when I see deer walk in front of me (although I do geek out with my camera). They have free nature walks, suitable for all ages, on weekends. There is absolutely no reason for active kids to stay indoors in Sacramento, especially when school is out!
So, turn off your media, folks, and take a hike here. You'll be glad that you did. It is part of Ancil Hoffman Park and there is a $5 parking fee for the entrance. The nature trails are free of charge. I do encourage becoming a member to the American River Natural History Association, especially if you have kids. Members get free parking and discounts for kids' camps.
