Take the highway leading north of Angola towards Caxito. The geological band of granite towers begins about 2 hours from Luanda. Past Caxito, turn north to Quicabo or continue east to Elephant Rock. For finding dirt roads beyond the paved roads that appear on Google Maps, it's useful to use an app like Gaia GPS to download satellite maps offline, and saving the coordinates of the rock towers beforehand. The easiest way to navigate here is following dirt roads on satellite imagery.
