Guam is located just south of the deepest point in the ocean, the Mariana Trench. The island is part of the Marianas Island Chain and the greater region of Micronesia. Despite it being the largest island in both island groups it is still only 48km long and 19km wide! The island formed by the fusion of two volcanoes that sunk beneath the ocean millions of years ago. A coral reef table surrounds the majority of the island with deep water channels. It’s proximity to the Mariana Trench leads to the area being known for its clear water. The coastline has rocky cliffs, mangroves and sandy beaches. The southern territory of Guam consists of high volcanic mountains, cascading waterfalls, traditional villages and lush agricultural land. At the same time, the northern section is relatively flatter and is where the majority of Guam’s population resides.
The capital village and hub of Guam is Hagåtña; it is the centre of the islands government, history, industry and commerce. It is a historical centre with architectural reminders of its 17th-century Spanish heritage and World War II military conflicts. Amidst all this, there are parks and plazas to take pleasant strolls through and enjoy a bit of relaxed sightseeing. Just a few miles away is Tumon Bay, Guam’s resort and entertainment region.
Modern hotels and resorts line Tumon Bay’s crescent of white, sandy beach. Adjoining these resorts are shopping centres, restaurants, nightclubs, and entertainment attractions, creating a centre of retail enjoyment. Tumon Bay’s entertainment attractions include Las Vegas-style shows, a tropical aquarium and boutiques featuring some of the most famous names in fashion.
Guam, with its historical landmarks and natural beauty, offers numerous sights of interest. In many locations throughout the island, Spanish influence is visible, such as the architectural design of Guam’s southern homes and villages. Discover the warmth of Guam and all her diverse personalities, glamorous resorts, entertainment, adventure, host of cultural crossroads and friendly, easy-going people.

Guam is the only place in the world where you can touch two ships in the one dive. The WWI German scuttled vessel, the Cormoran, touches the Japanese Tokai Maru from WWII which was sunk in battle, bow to stern, at 30 metres. The top deck of the Tokai Maru is at 14 metres, while the Cormoran's deck is at 18 metres. Both ships rest on their sides. Schools of fusiliers have made the wrecks their home.
The Blue Hole is Guam's signature dive, with visibility usually over 30 metres. The sinkhole's entrance is at 18 metres and opens into the cavern archway at about 35 metres dropping to 70+ metres. Triggerfish, Crocodile Needlefish and a variety of butterflyfish are common, while Napoleon wrasse, barracuda and rays can be found deeper along the wall.
The island's coastal highway takes you around its southern side with scenic lookouts, snorkelling sites and quiet villages offering glimpses into native Chamorro culture and everyday lifestyle of the local people.
Guam's turquoise lagoons, deep-sea currents and clear warm waters offer a myriad of water sports and activities - snorkelling, scuba diving, jet-skiing, windsurfing, sea kayaking and water skiing.
For those who prefer to remain dry, there are riverboat tours, dolphin watching cruises and a submarine dive for a close-up view of the island's fish and corals. Visit the walk-through tropical aquarium, enjoy a scenic round of golf, shop or restaurant and bar hop.
