Bikers of all ages and abilities will find a trail perfect for them in parks, near beaches, through forests and marshland and in Quincy’s neighborhoods. You can’t ask for more varied terrain than that found in the Blue Hills Reservation, a 7,000-acre urban park with 125 miles of hiking and biking trails through forests and pine woodlands, by ponds and bogs. You’ll see right away why it’s such a popular park for bikers and hikers. Mountain bikers are welcome and will find the trek up to the weather observatory particularly satisfying, especially with that Boston skyline view as a reward. With 27 miles of shoreline, Quincy boasts great beach and water views, too, for bikers, especially in the Quincy Shores Reservation.
