Salem is on the MBTA commuter rail, on the Newburyport/Rockport line out of North Station, and the ride is 36 minutes on the September 2026 timetable. The station is a ten-minute walk from the downtown grid where almost every local tour meets. When we checked, a weekend commuter-rail pass was $10 for unlimited travel across Saturday and Sunday; weekday single fares are higher, so check the MBTA’s own page for the day you are travelling.
So the arithmetic, for two people on a Saturday: $20 of train against $380 for the pair on our pick here, the full-day witch trials trip at from $190 each. Add a local walking tour from $25 a head and you are at $70 for the day with a guide in Salem itself, against $380 for a guide who is with you from Boston and back. The cheapest listing on this page, the train trip, is $240 for two.
What the guided day buys, then, is not access — it is not having to plan it, a guide for the whole day rather than ninety minutes, and in two cases a second stop at Hammond Castle in Gloucester, which is genuinely awkward to reach without a car. On an October Saturday it also buys a seat: the trains fill and the town is at capacity.
