Guam is the largest (543 sq. kilometres) and most populated island, situated at the southern end of the Marianas chain. Just south of the island is the Marianas Trench, the world’s greatest ocean depth - 10,925 meters.

Hagatna, is a busy capital city and the hub of Guam's business and government activity. It is a historical centre with architectural reminders of its 17th-century Spanish heritage and World War II military conflicts. Amidst all this, Hagatna's parks and plazas invite pleasant strolls and relaxed sightseeing. Just a few miles away is Tumon Bay, Guam's resort and entertainment region.

Tumon Bay's crescent of white, sandy beach is lined with many modern hotels and resorts. 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 great tropical aquarium and boutiques featuring some of the most famous names in fashion. 

Guam, with its historical landmarks and natural beauty, offer numerous sights of interest. In many locations throughout the island, Spanish influence is clearly visible, such as the architectural design of Guam’s southern homes and villages.

The graceful remains of Spanish buildings, the Plaza De España and stone bridges may be seen in Hagatna, Guam’s capital. Discover the warmth of Guam and all her diverse personalities, glamorous resorts, entertainment, adventure, host of cultural crossroads and friendly, easy-going people.

  • Geographical Information

    Diving in GuamThe island was formed by the fusion of two volcanoes that sunk beneath the ocean millions of years ago.  The majority of the island is surrounded by a coral reef table with deep water channels. The coastline is characterised by rocky cliffs, mangroves and sandy beaches. The southern area of Guam consists of high volcanic mountains, cascading waterfalls, traditional villages and lush agricultural land, whilst the northern section is relatively flatter and is where the majority of Guam's population resides.

  • Guam Activities

    Scuba Diving in GuamThe 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 offers a myriad of water sports and activities - snorkeling, scuba diving, jet skiing, windsurfing, sea kayaking and water skiing. For those who prefer to remain dry, there are river boat 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.

  • When to Travel to Guam

    The dry season is between January and May whilst the rainy season (if Guam has one) is between September and December, meaning there are combinations of rain and sun throughout the day. January to early April are the windiest months when the tropical northeast trade winds are active. The calmest months are from late April to August. Most dive sites are on the leeward (west) side of the island and can be dived year round. Temperatures range between 24-30 degrees Celcius every day.

  • Scuba Diving in Guam

    Scuba Diving in GuamWhilst not quite comparable to scuba diving in Palau, Truk or Yap, diving in Guam is still better than many other areas of the world. Guam has warm, crystal blue water and a choice of reefs, spectacular walls, drift dives, planes and shipwrecks. There are over 75 different and easily accessible dive sites for both boat and beach diving, over 200 species of coral and lots of marine life. The diving in Guam is generally very easy and water temperature is around 28°C year round with good visibility at most locations. Dive sites in Apra Harbour ranges from 10-20 metres whilst the outside reefs are clearer with 30 metre plus vis. 


    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 in excess of 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 butterfly fish are common whilst Napoleon wrasse, barracuda and rays can be found deeper along the wall.
