Outdoor classes for toddlers?

Any other parents found any good options for outdoor classes for their young toddlers? Preferably around the Spring/Woodlands area but I'm willing to drive. Would need to be for under 2's. I've found a few via Google but they are links to sign up pages from like 2018 and that's not helpful.

Ours is 16 months and I have him in an outdoor music class which he's so so about, but I haven't been able to find anything else that's outdoor except enrolling him in the next session of music class.
