Essential Travel Tips
Don't leave Guam without trying kelaguen! It's a local delicacy made with chopped chicken, shrimp, or fish, mixed with lemon juice, coconut, and spices. You'll find it at almost every local eatery and family gathering – it's the perfect blend of tangy and savory.
Renting a car is your best bet for exploring Guam at your own pace, especially if you want to hit up the less-trafficked beaches and historical sites. While taxis are available, they can get pricey for longer distances, and public transport is limited outside of the main villages.
Embrace the 'Fino' Chamorro' (Chamorro language) by learning a few basic phrases like 'Håfa adai' (hello) and 'Si yu'us ma'åse'' (thank you). Locals really appreciate the effort, and it opens doors to warmer interactions and a deeper understanding of the island's rich heritage.
While credit cards are widely accepted in hotels and larger stores, always carry some cash for smaller roadside stands, local markets, and tipping service staff. ATMs are available, but it's good to have smaller bills on hand for spontaneous purchases, like fresh fruit from a farmer's market.
Pack light, breathable clothing and plenty of reef-safe sunscreen. The humidity is no joke, and protecting the delicate coral reefs is a big deal here. Don't forget a reusable water bottle – staying hydrated is key, and you can refill it at many hotels and public spots.
Be aware of rip currents when swimming in the ocean, especially on the eastern side of the island. Always check local beach conditions and heed any posted warnings. The waters are generally safe, but it's wise to be informed and swim with a buddy.
💡 Travel Tip: If you're planning your trip, it's worth checking flight prices on Trip.com before you decide.

Frequently Asked Questions
When's the absolute best time to visit Guam to catch the best weather and avoid the biggest crowds?
Honestly, the sweet spot for Guam is typically from December to May. This period falls within the dry season, meaning you'll get plenty of sunshine and lower humidity, perfect for beach hopping and exploring. While it's popular, it's generally less crowded than the peak summer months, giving you a more relaxed experience.
I'm interested in experiencing the local culture. What's a respectful way to engage with Chamorro traditions?
The best way to honor Chamorro culture is to be open and respectful. Always ask permission before taking photos of people, especially elders, and if you're invited to a gathering, it's a huge compliment! Try to learn a few basic Chamorro phrases like 'Håfa adai' (hello) and 'Si Yu'os mås hågo' (thank you); it goes a long way with the locals.
Getting around Guam seems a bit tricky. What's the most practical way to see the island?
While there's a public bus system, it's not the most convenient for tourists wanting to explore freely. I highly recommend renting a car; it gives you the ultimate freedom to discover hidden coves and scenic viewpoints at your own pace. Just be aware that driving is on the right side, and while roads are generally good, some smaller routes can be a bit rough.
Beyond the popular beaches, are there any 'must-see' spots that most tourists miss?
Absolutely! Don't miss the War in the Pacific National Historical Park, especially the Asan Bay Overlook for incredible views and a dose of history. For a truly unique experience, hike to the cross at Mount Lamlam, the highest point on Guam, for breathtaking panoramic vistas, especially at sunset. It feels like you're on top of the world!
What's the deal with currency and tipping in Guam?
Guam uses the US Dollar, so no need to worry about currency exchange! Tipping is customary for good service, similar to the mainland US. A 15-20% tip is standard for restaurant servers, hotel staff, and tour guides. It's a nice way to show appreciation for the warm hospitality you'll undoubtedly receive.
I've heard about the 'Island Time' phenomenon. How should I prepare for it?
'Island Time' is real, and it's part of Guam's charm! Things might move at a more relaxed pace, so patience is key. Don't get frustrated if service is a little slower than you're used to; embrace the laid-back atmosphere. It's a great reminder to slow down, enjoy the moment, and soak in the tropical vibes.
