looking for spring wildflower/spring ephemeral hikes

Okay - I'm looking to take a short hike with some kids in early April (first week), with the hope of doing some spring ephemeral wildflower id'ing. If I were with adults only/by myself, I'd opt for going up to Joyce Kilmer (went last year around the same time and it was magical), or up to the Cohutta wilderness, or to Sosebee Cove or Warwoman Dell.

However, I need to stick within about an hour of Atlanta - so that limits me to not too far past Dawsonville/Dahlonega, or near Tallullah Gorge. I have been poking around the map near Amicalola Creek, but not found much promising. Any ideas for a trail (ideally similar in wildflowers and length to the Sosebee Cove Trail) that might be suitable for kids?
