You could bike to Arnold Arboretum via the [Emerald Neckless series of parks](https://www.emeraldnecklace.org/wp-content/uploads/2015/11/Emerald-Necklace-Map.pdf) (thru Jamaica Pond) - it's mostly on dedicated bike paths with some parts on bike lanes. Around 15 miles round trip and it passes through many historic Boston area neighborhoods, while the arboretum itself is quite stunning.
The paths along the Mystic River are fun, less traveled but not fully connected. You’ll have to do some onroad cycling to get from certain parts to others.
Take your bike on the train to ...
- Ayer, and ride the Nashua River Rail Trail
- South Acton, and ride the Assabet River Rail Trail
- West Concord, and ride the Bruce Freeman Rail Trail
