Crisp days and changing foliage beckon! Join the Emerald Necklace Conservancy for a guided, interpretive bike tour from the Back Bay Fens to the Arnold Arboretum, led by a Conservancy docent. Bike along the Emerald Necklace during the time as fall foliage comes through and Emerald Necklace's trees change colors. Get to learn about historical sites and interesting facts within the Emerald Necklace. All attendees must bring their own bicycle.
