The cache is located just beside the highest postbox in altitude.
Three ways I suggested, you could use to find the cache.
- Way #1 - ask the police officer at the posted coords. This police station is very close to the postbox. (Proved not working that officers don't know where the postbox is.)
- Way #2 - use the Internet. The link 中華郵政 - 信筒(箱)設置地點查詢 here, you could search for postbox closest to the posted coords. (Proved not working that China Post removed the data of the postbox.)
- Way #3 - use the spiler photos.
And sure, there are many ways that you could find it. Hope that you enjoy searching Taiwan's highest postbox as I do. Yet? ^^
