One of Massachusetts' tallest mountains is now home to the Purple Valley MTB trails.
When Bill MacEwen moved to Williamstown, Massachusetts, he was surprised by what he found. Or, actually, what he didn’t find. Despite miles of rolling hills, densely forested areas, and multiple river valleys, the area had very few mountain bike trails.
Thanks to the quick organization of a new local trail group, Williamstown is now home to roughly five miles of singletrack. And more are on the way.
