There are lots of places to access the Meehan Range (check out Google Earth). Most of the "tracks" are actually roads so be aware that you are likely to meet mountain bikers and possibly trail bikers (especially weekends) - Cambridge at Belbins Road is one end, Downhams Road Risdon vale is another access point plus the Flagstaff Gully link road has some access points but be aware that one access is via the gun club!
