We had such a fun birthday party at Central Rock Arsenal Yards. Kailan and Myka went above and beyond to make it special. The gym is beautiful, clean, and had plenty of climbs our group of 7 year olds could do. Highly recommend!!
Very nice gym. Nice and clean. Staff was really polite. Very easy to find and (it appears; I’m from out of town) parking is easy to find. Note that this is a ropes-only gym. They do have auto-belays though, which is nice and unusual. Only downsides are that this place is really small. I think maybe 50 routes. And except for one area the walls are very short, maybe 30 feet high at most??? The grades looked slightly soft for all but the higher 11s and 12s. But if you want a simple easy place up to, definitely come here!!!
Great gym! I wish they had some equipment to warm up with, but I respect the choice to maximize climbing wall space rather than adding a workout area
We came here for father’s day and we had an amazing time. And honestly i think the staff made it so relaxing. Especially Kirsten, she’s really helpful and will teach you everything you need to know about rock climbing without giving you a bombastic side-eye if you ask questions. She’s really the person you need when coming here for the first time. Everyone needs a Kirsten in their life, she’s an angel.
I found the concept super neat. I was on my way from another gym in the area and semi accidentally ended up in Arsenal Yards. I decided to do some cool down traversing here and thoroughly enjoyed the vibe. The idea of bringing the epic CRG quality to an accessible area with a lot of foot traffic is pretty neat and compliments the main Watertown facility well. Other cool things - good hold selection and good use of holds. The interesting holds also found their way onto some of the more accessible climbs which I thought was cool! - very clean - well lit
