Fun with animals
Mass Audubon’s Drumlin Farm Wildlife Sanctuary is less than 3 miles from Walden Pond. In addition to a variety of short hikes, it’s a working New England Farm as well as a wildlife sanctuary featuring over 150 species of birds. If nothing else, walk the loop that takes you past Bird Hill, the Sheep Shed, and the Pig Barn.
As a working farm, there’s a produce stand at Drumlin Farm that is usually open and they have great basil.
Mass Audubon members get in free. For non-members, it’s $7 per adult and $5 for children ages 2 to 12.
