The other way way is to walk till Ghera village(not advisable). From Mcleodganj you walk to Tingle Board (2-3Kms), then to Dal lake which is a tourist spot and then to Satovri village (4Kms). From Satovri village there is a trail leading to Ghera Village (5-6 Kms of Descent), you have to pass through 2-3 Villages before reaching Ghera. I walked from Dharamkot to Ghera, amidst the rain and I was the only person using this route. This is not advisable unless you are physically very fit and ready to take on challenges.
