Is this mall near the MTBA for access to Boston? Looking to park RV for the day and go into Boston

It's about a 10-15 minute walk to the Chestnut Hill "T"station on the green line.

You can take the 60 bus, u can take to a few stops for the d line

You should think of parking your RV at Riverside train station. This stop is off 95 and has parking big enough for an RV.

Not a good idea

There is a bus also that runs to Kenmore station.

It's a good 12-15 walk.
