A short 3-minute walk from the parking lot will take you to a picnic shelter built atop the foundation of a WWII radar tower. Built in relative secrecy, the radar site was intended to scan the skies for Japanese aircraft. Overlooking the other defenses built on Japonski Island, the site was complete with a storehouse, mess hall, barracks, and mounted machine gun. The site was active from July 1942 until the end of 1946. Today, it is home to some of the best picnic views on the island. As for this easily accessible cache, just a few steps away, in the center of the gnarled stand, your toes will know. Make sure to check out all the hidden picnic sites while you are here for some great views.
