The original McComb Trig was constructed in 1881, but nothing remains of the historic structure. The current trig station – consisting of a concrete pillar and metal mast and vanes – was built in 1973.
The current trig is reasonable condition, but is the nameplate is missing.
Getting to McComb Trig
The trig station is near one of the access trail to the Manly Dam Circuit bushwalking and mountain-biking trail. From the Manly Vale Public School, a signposted trail heads towards the Manly Dam trail; after about 200m look for an un-signposted trail to the right. This goes up to the trig point, which is right next to the informal bushwalking/MTB trail.
