Piti Bomb Holes Marine Preserve

The Piti Bomb Holes Marine Preserve is a protected zone in Guam's bay featuring natural pits carved into the reef flat. These holes descend 7 to 9 meters deep and allow fresh water to filter into the shallow lagoon below.

The area was designated as a marine protected zone in 1999, leading to significant recovery of fish populations. This action marked a turning point in protecting the island's ocean resources.

The waters here connect to fishing traditions that local families have practiced for generations. Visitors walking through the marine park can sense how these customs remain woven into the community's relationship with the bay.

Visitors can explore the underwater observatory at Fish Eye Marine Park, descending about 9 meters below the surface to watch marine life through viewing windows. The site is accessible and offers a safe way to see the protected waters without requiring diving skills.

Guam's first coral nursery started operations here in 2013, working to regenerate damaged reef areas. This facility uses special structures to support coral breeding and growth in the protected waters.
