Cambridge Bike Route – Opportunity Loop

If you’re looking for a solid loop to get some miles in without dealing with traffic, this is the go-to spot for Cambridge locals. The paved path works just as well for a casual walk as it does for a proper bike ride, so you’re not stuck sharing space awkwardly with people going half your speed. It winds through the city in a way that actually feels like you’re going somewhere, not just lapping a parking lot. Families with kids on bikes use it constantly, and it’s flat enough that nobody’s getting left behind.
