For the ease of walking it is best to do the Kowloon Park stage of the ”KOWLOON PENINSULA” Adventure Lab Cache last, as this is closest to the “Bonus” Location.
At each stage of the Adventure Lab you will be given a BONUS CODE that will help you find this cache. The code will be some letters and all the numbers that you will need for the actual coordinates. The letters will spell the general location of the cache.
You will only be able to log this cache upon the completion of the KOWLOON PENINSULA - ADVENTURE LAB.
