Fish Eye Marine Park is pleased to announce that its iconic Underwater Observatory has officially reopened following the successful replacement of six of its twenty-four viewing windows. 

The upgrades, completed on Sept. 14, 2025, allow visitors to enjoy clearer and brighter views of Piti Bay’s thriving marine life, offering a refreshed experience at Guam’s only Underwater Observatory.

“This project begins a thoughtful process of phased improvements, ensuring that guests continue to enjoy vibrant views of Piti Bay,” said Akihiro Tani, General Manager of Fish Eye Marine Park. “The new windows already provide a noticeably clearer look into the reef, and we are excited to welcome back visitors to see the difference for themselves.”

To celebrate the observatory’s reopening, Fish Eye Marine Park is offering an exclusive lunch package that combines dining with discovery.

Every lunch buffet at Fish Eye’s Garden Restaurant now includes a complimentary visit to the Underwater Observatory. 

Guests can savor a freshly prepared island-style buffet, then proceed to the observatory for an unforgettable, up close view of the marine life in Piti Bay.

This promotion is perfect for families, tour groups, and residents to enjoy the best of both worlds, a delicious cuisine paired with one of Guam’s most unique attractions in a single visit.

The refurbishment is part of Fish Eye’s preparations for its upcoming 30th Anniversary in April 2026. 

Other initiatives include the establishment of Friends of Fish Eye, a nonprofit organization focused on the preservation of the Piti Marine Preserve and environmental education for Guam’s youth.

“Our anniversary is not just about celebrating the past three decades,” added Tani. “It’s about looking ahead, investing in the observatory, protecting the bay, and inspiring future generations to appreciate Guam’s natural beauty.”

Fish Eye’s Underwater Observatory remains the centerpiece of the park’s offerings, alongside the Island Cultural Dinner Show, snorkeling tours, dolphin and sunset cruises, and the Island Heritage & Coconut Experience, making it a must visit destination for both visitors and residents.
