Mt Karangahake towers above the western end of Karangahake Gorge, between Waihi and Paeroa. It is clearly visible from SH2, the main road through the gorge. The most prominent peak has a trig station on top, with an official elevation of 544m above sea level. The highest point is a few metres higher, but not easily accessible. However, a nearby peak with a communication mast on top is accessible, and is slightly higher than the trig station.
There are 3 tracks leading to the summit, all of which are accessible from the main carpark on SH2, or from the nearby carpark on County Rd, or from Crown Hill Rd where there is a small parking area near a locked gate. There are toilet facilities both at the main carpark, and by the County Rd carpark. County Rd is accessible from SH2 across a one-lane, two-level bridge, originally used for both rail and road, with the railway above the roadway.
