Hike to Wally's Cave on Lion's Head

At the bottom (not really the bottom, but the parking on the way to Signal Hill) you take the jeep track until you reach the paragliders launch point. There you will see a tiny little stairway path heading up to the right.

Follow this path up until you see a massive rock, pass it and take the path on your left. There's a split somewhere that takes you directly down again, so keep right. Follow that and around the corner you will find... Wally's Cave.
