Hello, We have booked the Ghan from Darwin to Alice with return to Adelaide in August. I need advice re fitness/mobility requirements for tours from Alice Springs. This is our first trip up north. We require specific info given that I have some mobility arthritis difficulties though can walk etc (I do not need escort or wheelchair) if I know distances and degree of slopes/paths. Having a nice safe place to stay with cultural tours would be preferable and my husband can do higher fitness activities on a daily basis. I need informed information. Travel agents have just given us books and no informed advice. there is no activity/fitness legend in the mag's.
