Not recommended for toddlers. kids around 10 or more are good. Females have to hike around 3 to 4 hours. see if this suites your ladies...
Till Jaazbaanda, you have to do jeep safari (1 hour) + 3 to 4 hours hiking, mountain climbing and trekking. You have to hire jeep costing around 6k from Thal till TakiBaanda where jeep will leave you and ask you when your arrival will be. don't pay the driver anything till your return otherwise the drivers will not come back. After TakiBaanda there is hiking and it will take you to Jaazbaanda. Better hire a porter who will be your guide too.
Hope this will help ...
