On the maps or guide books? Yes they are and all the huts are sign posted by a hut symbol at the junction from the track. Some huts are on the track but some are up to 200 metres off the track and usually uphill. All the toilets are all uphill. I hate that

Enjoy the walk, the flowers are going to be amazing. Just remember that walking can be hand work for the first couple of days, then you get trail fit, so hang in if it seems too hard. Take some treats to get you through. I listen to music thru head phones if I feel I need a treat.
I have been reading a book on the AT in USA (which the bibb was modelled on) and the author wisely says, you can never go up a hill slowly enough. I look forward to reading your entires. I was down at donnelly river to tom road a couple of months ago. My trail name is Rogo. Original huh!
