Both my son and I are very fascinated by the mountains around the island, and all the great caves and holes, witch are used by ex. birds. We 've enjoyed and discovered nests in many places.
One night we were out on our evening hike we discovered this area. My son explored holes and caves high and low. It was then he came upon the idea that this would be a perfect place for his cache. Next day the perfect box shows up.
The cache do not contain pen. Please bring your own.
Happy hunting :-)
