Approach notes

From the car park at the gun battery, find the purple brick path which eventually leads to the monument for those lost at sea. From the metal gate, follow the purple path for approximately 20 yards at which point it starts to gently curve to the left. Duck into the bushes to the right to find a path (not obvious). If you are doing some serious bushwacking then you are off route. Follow the path down through the jungle which appears to have been made by Hobbits past a fallen tree. Eventually the path starts to go back uphill. Around this point take a 90 degree left branch and follow this steeply downhill to clear the jungle. At this point you should be able to see The Pump Room straight ahead. Follow the path down some steps and a short but easy downclimb to ledges at sea-level.
