A Guam cruise reaches the largest island in Micronesia and the westernmost US territory. This strategically important Pacific island blends indigenous Chamorro culture, a strong US military history, and tropical beaches. Cruise calls are relatively limited and come mostly on Asia-and-Pacific repositioning routes and the occasional regional sailing, with ships docking at Apra Harbor near the capital Hagatna. Guam is more often a flight-and-stay resort destination than a major cruise port.

For cruisers, Guam offers an unusual mix. Think the white-sand resort beaches of Tumon Bay and the moving World War II history of the War in the Pacific National Historical Park. Add the indigenous Chamorro culture and the convenience of the US dollar and English. Two Lovers Point offers dramatic clifftop views, the Latte Stone Park preserves ancient Chamorro pillars, and the diving in Apra Harbor is excellent. As a US territory, it is straightforward for American travelers in particular.

Quick Facts

Best Time to Cruise

Guam has a tropical climate with cruise access year-round, with a drier season from December through June and a wetter season from July through November (which overlaps the typhoon season). The drier months bring the most reliable weather.

Cruise calls track the Asia and Pacific repositioning calendars rather than Guam specifically, so availability matters more than season. Browse the latest Oceania cruise deals for the itineraries that include Guam.

For the best mix of drier weather and lower typhoon risk, sail in the December-to-June dry season. The July-to-November wet season is warmer and carries typhoon risk. For most cruisers, Guam features on an Asia-and-Pacific repositioning route or a regional sailing rather than a dedicated cruise destination.

Top Cruise Ports

Apra Harbor (for Hagatna and Tumon)

Apra Harbor, one of the great deep-water harbors of the Pacific, is Guam’s cruise port, with the capital Hagatna and the resort district of Tumon Bay a short drive away. The harbor itself carries significant military and World War II history.

The draws are Tumon Bay’s resort beaches and the War in the Pacific National Historical Park. Add the Latte Stone Park and Plaza de Espana in Hagatna, Two Lovers Point’s clifftop views, and the excellent diving. Insider tip: the War in the Pacific National Historical Park sites are the most significant Guam excursion, documenting the fierce 1944 battle and the island’s pivotal Pacific-war history. They pair well with the indigenous Chamorro heritage sites in Hagatna.

Which Cruise Lines Sail Here

Guam is a limited cruise stop, mostly on repositioning and regional routes. The premium lines lead among Western lines. Princess includes Guam on Asia-and-Pacific repositioning sailings, with Royal Caribbean and others calling occasionally.

Regional Asian cruise lines call at Guam on Japan-and-Micronesia and Western Pacific itineraries, since Guam is a popular destination from the Japanese and Korean markets.

Expedition lines occasionally include Guam on Micronesia-focused voyages exploring the wider region. Most Guam calls come on Asia-and-Pacific repositioning routes or regional sailings rather than dedicated cruises. Read our Princess review, our Royal Caribbean review, and our Celebrity review for the kinds of lines that reach the western Pacific, and check which itineraries actually include Guam.

Shore Excursion Tips

Guam is one of the easiest Pacific cruise stops for travelers, especially Americans, thanks to English, the US dollar, US infrastructure, and easy car rental. A do-it-yourself day by rental car to Tumon Bay, the war sites, and Hagatna works well.

Book through the ship or a reputable operator for the War in the Pacific historical-site tours and any diving excursions in Apra Harbor. The same goes for combined island tours covering the Chamorro heritage and the scenic viewpoints.

English and Chamorro are both official, and the US dollar is the currency, with cards accepted everywhere and standard US tipping. Try the Chamorro specialties like kelaguen, red rice, and kadon pika. As a US territory, Guam is very straightforward for American travelers; others follow US entry rules.

Sample Itineraries

Packing & Practical Tips

Pack light, breathable tropical clothing for the year-round warmth and humidity, plus swimwear (essential for Tumon Bay), reef-safe sun protection, and a hat. Bring water shoes, a snorkel set if you dive or snorkel, comfortable walking shoes for the historical sites, and a light rain layer for tropical showers.

Guam uses the US dollar and standard US Type A/B plugs, so US travelers need nothing extra while others need an adaptor. Cards work everywhere and US tipping applies. Tap water is safe. As a US territory, entry is simple for Americans; others should check the US and Guam entry rules. For the full list, see our cruise packing guide.

The Verdict

Guam is an unusual but rewarding western Pacific cruise stop. It blends indigenous Chamorro culture, significant World War II history, resort beaches at Tumon Bay, and the convenience of being a US territory. It is more often a flight-and-stay resort destination than a major cruise port, so it appears mostly on Asia-and-Pacific repositioning routes. But the war history and the easy US logistics make it a worthwhile call when it features.

Book a cruise that includes Guam if you want a US-territory Pacific stop with moving war history and easy logistics, most likely on a Princess Asia-and-Pacific repositioning route. Prioritize the War in the Pacific National Historical Park, pair it with the Chamorro heritage sites in Hagatna, and enjoy Tumon Bay’s beaches. For the best weather, sail in the December-to-June dry season.
