If you can find a way in forest you can find way in any TREKK... else visit trekking in HIMACHAL Pradesh..... I am local from tirthan valley minute found ways in moutains by my own...
1. Chopta trek (Rudraprayag)
2. Kedarnath trek
3. Valley of Flower/Hemkund Sahib trek
and many more
In fact, most of the treks can be done without guide...i did Kedarkantha trek without guide in one day...on the other hand, some travel agencies are making guides compulsory and completing the trek in 3-5 days...
