I'd love to take my kids (4 &6) on a hike where they will experience lush rain forest and maybe see ( not swim in!) a waterfall. I don't think we're going to do the road to Hana, it sounds like it would be a bit too much for them . Does an easy trail like this exist? Everything I've come across is either on the RTH ( if it was earlier on the road in might be ok) or is rocks on lava on the shoreline ( we'll try that too!).
