Weekly Field Cleanup Initiative
At PiPi, we conduct a “field cleanup” once a week on each island to protect the fields used for our tours.
Today, the entire staff got together again to clean the facility.
We will continue to collect washed-up trash, branches, and leaves to create an environment where future visitors can enjoy themselves comfortably.
