@ tiger727272, indeed it is.
@ hhh, Dunga Gali is about four Km from Ayubia on the road to Abbottabad / Nathiagali. The wildlife centre is situated in Dunga Gali, is just a bit beyond the main road. If you stop at the main road and ask some body you will easily find it.
From the wildlife centre buliding a dirt tract start which goes to Ayubia, takes about 2 hours to reach there, it passes through the park.
I advise you to be in touch with the officials at the wildlife centre for guidance.
