Hi,
See my past post on the bottom of this thread....
viewtopic.php?f=37&t=12622It was a cracker of a 4 day walk and we managed it with two adults (one with plenty of experience and weight carrying in a 90L pack) and 2 kids (one 9 and one 5). Probably not a first hike - but once you test them out it is amazing what you can do!
We did the razorback, feathertop, down diamantina spur and back up to Derrick's Hut and top of Hotham 2 years ago with 3 kids (5-8 y.o's), 3 adults. It was amazing and quite doable if the adults and kids are willing.
Here's my rules for hiking with kids.
- for 5 y.o's MAX of 2-3 kg and a tiny pack (these are very hard to find). In photo above Jaiya's tiny pack is a german pack which is miniature and sticks to her back perfectly. Forget hip straps but make sure there is a chest strap as they slip off their narrow shoulders easily
- for 7-8 y.o the osprey 35 litre packs are perfect...scaled down packs with hip straps and a frame. Max 7 kg - but they can carry their own sleeping bag, clothes and bedrolls
- good down sleeping bags are better than the crap kids ones they sell and will last till they are adults.
- We take only 3 sleeping bags and zip two together with our 5.yo in with us
- The Easton Hat-trick tent is an amazing lightweight 3 man which a family of 4 can comfortably fit in. we had it pitched in 40km/hr winds at bogong saddle this time around and it was stable as could be

- Don't worry about bedrolls for the kids if their sleeping bags are good. They could sleep anywhere and on anything!
- To give you an idea on what is possilbe - with 2.5l of water each for adults during the day, we ran packs at 25kg, 18kg, 7kg and 2.5kg and had enough for a family of 4 to be out for 4 days, 3 nights.
It truly is magic to watch kids feel the achievement and have the most fun in their lives without a toy or electronic gadget in sight.
Feel free to PM me if you want to know our other routes as it does take some planning to get the length of days right.
Beware - it is highly addictive....get into it

Cheers
Russel
