Fly High Kids Adventure Park Altadena

If you’ve got a toddler who needs to burn off some serious energy, this Altadena spot is worth knowing about. The zipline alone is enough to make little ones lose their minds in the best way, and the slides and climbing structure keep them busy long after you’d expect them to tire out. It’s indoors, which — if you’re local — you know matters when the San Gabriel Valley heat is doing too much. Prices are pretty reasonable compared to what you’d pay for less fun, and the staff actually seem to like kids, which isn’t always a given at these places. Best for the toddler-through-early-elementary crowd.
