Dear Brother, aansoo lake, Makra Peak, Babusar Top Trekking outside the roads are very dangerous but Dudipatsar trekking is safe, i recommended you to hire a guide with horse because trekking is much difficult and i have trekked there about 11:30 hours then i reached to Dudipatsar lake.
Although there is much more beauty on the whole trakk but if you have no practice then it becomes difficult....
