Gym Jamz Open Play

If you’ve got kids bouncing off the walls on a rainy day in Dartmouth, this is honestly one of the better calls you can make. The climbing structure and slides keep the under-12 crowd busy for a solid stretch, and the place is genuinely clean — like, noticeably so compared to a lot of indoor play spots. Staff are actually attentive and friendly, not just standing around scrolling their phones. Restrooms on-site makes life easier, and it’s become a go-to for birthday parties in the area, so book ahead if that’s your plan.
