Best Boston gym

Hello,

Looking to boulder in the gym tomorrow in Boston or Providence. I'm from out of town and flying out late in the day. Which gym is the best for bouldering/most accessible by public transportation?

Metro Rock in Everett has a shuttle from the orange line. 

If you're in downtown Boston.  Central Rock Boston is right by North Station.

If public transportation includes uber/lyft/etc., then Central Rock Cambridge is nice - it's all bouldering, 25 minute walk or 5 minute car ride from Alewife station on the red line.

Best bouldering by far is CRG Cambridge

Metro Rock Everett has competition problems still up

it's like a 15 minute walk to CRG Cambridge from the Alewife redline stop... no need for a rideshare

Late to the thread but IMO Rock Spot South Boston is a strong contender for best bouldering gym in the area.
