Of course we did get lost for awhile going off the trail in search of the ruins of the Japanese temple which is hidden somewhere near the reservoir. The temple was built by the Japanese during the war. Apparently the Japanese destroyed the temple themselves just before the surrender to avoid the British blowing it up when they returned. We never did manage to find the temple, so if anyone can give me clear directions on how to get there please do let me know!
For those who are thinking of looking for the temple, I would advise going only with someone who knows the way, or at the very least with a compass and a means of contacting people who will know to send out search parties if you don't return.
