I'm getting my daughter pretty excited about going bushwalking with me - she's only 11, and wants to do the OLT at some stage very soon...

As preparation, I wouldn't mind taking her on some small but challenging 2/3/4 day walks (walk in, stay the night, explore, walk out) - we've already done Cynthia Bay to Narcissus Hut, and we're about to do Pine Valley in a month...
I've heard you can walk in to New Pelion hut from the Arm River carpark - is that suitable? Can you get to any of the other huts without needing to start at Cradle? Scott Kilvert Hut maybe?
Any thoughts appreciated!
