Namaste Anil Ji,
regarding your question,

You can Trek from Godwari to Bajrabarahi and From Bajrabarahi to khokana to Chandragiri.

Route option: Godawari, Bajrabarahi- (Bungamati-khokona)- changlakhel - pharping or chandragiri.
There's a back road, down from the hill, where you can walk up to Chandragiri hills.

Thanks

Anyone who is interested they can make there own through Google Map, I'll recommend the following itinerary;
Day 1:
1) Godavari - Lele Hike 2Hr.
2) Lele -Tika vhairab 1hr.
3) Tika Vhairab - Champi 2 hr.
4) Champi - Bansbari (Pharping) 2hr
5) Bansbari - Hattiban 1hr (camp)

Maybe Champi to Bansbari it will take 1 more hour. it depends on hikers. From Champi to Dukuchaap it's totally downward and has to cross the Bagmati river which is the fault section in-between Lalitpur and Kathmandu District than need to hike totally steep to the Bansbari.

Day 2:
1) Hattiban - Champadevi 2hr
2) Champa Devi - Bhasmasur danda 1.5 hr
3) Bhasmasur danda - Deurali Ropeway
station 1hr
4) Deurali - Chandragiri 45 min

Note:
Please Carry plenty of water from Hattiban, no water fill-up point until Deurali.

Hope this help to you!
Thanks,
Sujan

Thankyou so much..
