Try this spot on the right/East side of SH1, this is North of the military area. Take the center track and follow it back take you to the pylons and there’s a nice spot right where that track meets the pylon service track. There’s often Beehives near the start of the track.
Also Tree Truck Gorge road a bit further North of that has lots of tracks off it.
Kaimanawa Road leading to the Pillars Of Hercules has several doc sites.
