It's easy to find nature in the city - Boston is green with parks, trees, and gardens. The Boston Nature Center is a gem, and worth the short drive to Mattapan. It's part of the Mass Audobon, and they have a weekly drop-in class for ages 3-6 called Early Explorers. Each week they present a different theme, and we have been so impressed with the teachers and topics.
If the Early Explorers class doesn't fit into your schedule, it's worth a visit anytime to explore the play area and hike on the trails.
The spring is a perfect time to go - let us know what you find!
