Once you arrive at the cache coordinates, simply climb the stairs and proceed indoors. The cache is a basic RubberMaid container, and holds a logbook, some small toys, and photos of my children. If you have trouble locating the cache, please ask one of the other rangers for assistance.
Small note on cache maintenance: I have made arrangements with the wildlife rangers at Kibale NP to maintain this cache. Also, I and/or colleagues of mine, will return to Kibale National Park at least once a year to maintain the cache.
