Just asked Daewoo. They currently take you to Abbotabad. From there you take (public transport) mini vans to paras, kaghan, naran etc.
I was in Sharan last year. Actually went to Shogran. Then decided to go to other side of mountain to Sharan. Jeep wala took 3500 rs. for round trip (pine lark shogran to sharan and back to pine park). Great experience overall.
