There are several entry points to Manly Dam, however the only vehicle access is through the main entrance at the end of King Street (off Condamine Street, Manly Vale). From this entrance, Sir Roden Cutler V.C. Memorial Drive provides access to the four picnic areas and carparks.
A footpath from the main entrance allows for pedestrian and disabled access into the park without having to go on the road. This currently runs to Section 2.
Other access points to the dam are located in the surrounding suburbs of Allambie Heights, Frenchs Forest, Manly Vale, North Balgowlah and off the Wakehurst Parkway.
The best access points for the bike track are; Gibbs St, Manly Vale and Upper Clontarf or Kirkwood St at Bantry Reserve, Seaforth.
