【Free Popcorn】☆Anthony Reed's Magic Show - Now, popcorn is being given away to all tour participants!

Sunset cruise begins. This is a special tour that includes an underwater observation and island BBQ at a popular restaurant. This new tour is packed with ALL in One Guam's attractions that can be enjoyed by all generations.

Campaign is now in effect.1 child (6-11 years old) free for every 2 paying adults (12 years old and up).
Eligible period: 12/18/2023 - 03/31/2024
GUAM LAB will adjust the rate for those who are eligible for the campaign after making a reservation upon request.

The unique Fish-eye Underwater Observation Tower, the only one of its kind in Micronesia, is located in the middle of the coral-blue Piti Bay Marine Protected Area. 24 large underwater observation windows allow you to observe more than 200 species of colorful tropical fish and natural coral reefs. Every day, thousands of divers visit the beautiful coral reefs surrounding the observation tower. It is worth seeing the schools of tropical fish swimming after the divers.

At the pier, while feeling the refreshing sea breeze, you will be dazzled by the beauty of the blue color that changes with the depth of the coral reef, from the emerald green shallows to the deep, clear, dark blue waters. The 72-step spiral staircase leads to a 10-meter-deep underwater observation deck with 16 large windows and 8 children's windows for a 360-degree view of the real undersea world.

Sunset cruises are a great way to enjoy the ever-changing colors of the sky and ocean on the ocean while the sea breeze blows. If you are lucky, you may even see a school of dolphins. Soft drinks and beer (up to 2 cans) are free during the cruise. The schedule changes seasonally according to the time of sunset.

Dinner is a Island BBQ dinner at Jamaican Grill, popular with Guam locals.

Transportation from the hotel is included. If you do not need it, please indicate that you don't need it and receive a discount of $10 for adults and $5 for children (6-11 years old).
