The Impossible Journey from John Bonner on Vimeo.
Here's the safest route I can find from Marblehead to North Station, Boston. From there is an easy hop onto the Charles River bike path, and points west
There is a faster route that takes you into East Boston and through Chelsea that I often use, but many might be freaked (unnecessarily in my view)
by using Route 107 all the way in, and negotiating the Rotary at American Legion Highway in Revere (my advice: be bold!).
You can see my movie about the route here:
