Preparation

Guam is known for its strong UV rays, saline environment, and coral terrain. Preparing before you leave is crucial to fully enjoy your “Water Activities in Guam.”

At least two swimsuits (considering drying time)
Rash guard, aqua shoes (to protect feet from coral/shells)
Snorkel, mask, snorkel vest (for personal hygiene and fit)
Waterproof pouch, simple first aid kit (disinfectant, waterproof bandages, etc.)
Reef-safe sunscreen

Preparing the basic items you’ll need during your trip ahead of time will save you time locally. Simple emergency kits, waterproof packs, portable temperature control towels, and sand brushes may be more useful than you expect.

Prepare Travel Essentials

Tip

Protecting valuables during water activities is key. Using waterproof packs, mini locks, and hotel safes together can reduce the stress of loss.

Transportation

The flight time from Korea to Guam Antonio B. Won Pat International Airport (GUM) is generally around 4 to 5 hours. The time difference is about one hour ahead of Korea (Guam UTC+10, Korea UTC+9). It takes about 10 to 15 minutes by car from the airport to the Tumon center. Due to significant differences between peak and off-peak seasons, we recommend comparing and searching for flights 2-4 weeks before if you can adjust your departure date flexibly.

Book the Cheapest Flight Tickets

As part of your entry preparation, be sure to check whether an Electronic System for Travel Authorization (ESTA) is needed in advance. Generally, Korean passport holders need an ESTA, and we suggest checking the current requirements with the U.S. Embassy in Korea notices.

Note

Flight tickets have different refund/change conditions. Be sure to check “free baggage allowance,” “seat selection availability,” and “change fees.” If you bring snorkel equipment, also check the baggage regulations and weight.

Courses

Here’s a sample 3-day itinerary focused on “Water Activities in Guam.” Feel free to adjust based on local weather, waves, and fatigue levels.

Day 1: Get acquainted with water at Tumon Bay (Matapang Beach Park) → Snorkeling at Ypao Beach → Beach walk
Day 2: Morning dolphin cruise (choose option with snorkel/banana boat) → Afternoon parasailing or kayaking/SUP → Sunset at Gun Beach
Day 3: Fish Eye Marine Park → Piti Channel snorkeling experience → Evening stroll and shopping in Tumon

Recommendation

On the first day, start by getting your bearings in shallow and calm waters, and from the second day, increase the pace with boat activities to enjoy “Water Activities in Guam” without overexertion, especially suitable for families and beginners.

Tumon

Tumon Bay can be described as the base camp of a Guam trip. It’s suitable for families with children or snorkeling beginners since the waves are usually mild and the sea level is shallow. Resorts stretch along the coast, and public showers and restrooms are available in parks (Matapang Beach Park, Ypao Beach Park), making it a convenient starting point for your day.

Rental booths or hotel beach desks offer rental on an hourly basis for kayaks, SUP (stand-up paddleboards), life jackets, and snorkeling gear. During peak seasons, there could be waiting times for onsite rentals, so moving early in the morning or mixing in pre-reserved activities can help you use your “Water Activities in Guam” time more efficiently.

Estimated costs (converted to Korean won, subject to change based on exchange rates/season): Kayak/SUP hourly rental 20,000~40,000 KRW, Life jackets 5,000~10,000 KRW, Beach parasol/beach chair sets 20,000~40,000 KRW.

Note

Do not touch or step on corals while snorkeling to protect corals and marine life. Sharp coral fragments can cause injuries and also lead to environmental damage.

Ypao

Ypao Beach Park, located at the southwestern end of Tumon Bay, is a prominent snorkeling spot where you can easily find corals and tropical fish just a short distance from the shore, making it a highlight of your “Water Activities in Guam.” The park’s parking is often free, with plenty of grassy resting areas and shades. The water visibility can become cloudy following rain or on days with high waves, so utilizing the clear morning hours is advisable.

The best snorkeling point is slightly to the right (north) of the park’s center at the edge of the shallow reef. Avoid the reef channels where the currents accelerate, and stay away from areas with breaking waves as a basic safety rule.

Estimated costs (converted to Korean won): Participating in a snorkeling tour can cost 70,000~110,000 KRW (varies depending on equipment/insurance inclusivity). If bringing personal snorkeling gear, you can enjoy it for free, but ensure you wear a life jacket for safety.

Tip

During mid to high tides, buoyancy and sufficient depth make it easier not to touch the corals while swimming. Check the tidal information on site signs or weather apps for the best entry time.

Gun Beach

Known for its dramatic cliffs and open horizon, Gun Beach at the north end of Tumon Bay is also renowned as a spot for watching sunsets. The ground is gravel and rock, making aqua shoes very useful. On calm days, snorkeling is possible, but around the reef channel, the current can be faster than expected. For a mix of photography and landscape viewing among your “Water Activities in Guam,” visiting during late afternoon is recommended.

Note

Avoid entering the water at Gun Beach on days with high waves or swells. You can be swept up by waves and come into contact with rocks, possibly causing friction accidents. Always pay attention to the on-site warning signs and lifeguard instructions.

Fish Eye

Fish Eye Marine Park is a landmark in the Piti area. After crossing the long bridge and entering the round observatory, you can safely view living corals and fish through observation windows below the surface, offering a safe way to savor “Water Activities in Guam” even if you’re not comfortable swimming.

Estimated costs (converted to Korean won): Observatory admission 20,000~30,000 KRW, Snorkel & experience package 70,000~120,000 KRW depending on contents. You can choose to only visit the observatory or go for a package with a snorkeling guide.

Recommendation

If you have family members unfamiliar with swimming, explore the underwater ecosystem in the morning through the observatory and try snorkeling at the shallow beach in the afternoon for a smoother adaptation.

Boat

The Dolphin Cruise is one of the most popular marine experiences in Guam. Many programs depart from Agat or APRA Harbor, and based on local conditions, you’ll often anchor at a snorkeling spot after observing dolphins to enjoy free swimming. Combo packages that include banana boats, tubing, and fishing experiences are also common.

Estimated costs (converted to Korean won): Dolphin cruise 70,000~120,000 KRW, Parasailing 80,000~140,000 KRW, Combo type (boat + activities) 100,000~180,000 KRW size. There’s a significant difference depending on the components and inclusions (hotel pickup, photos/videos, gear, snacks).

Book Activities at Your Destination

Tip

Many prefer morning departures when the waves are relatively calm. If you’re prone to seasickness, take anti-nausea medication 30 minutes before departure and keep your eyes on the horizon while on board to help alleviate symptoms.

Safety

The most crucial aspect of “Water Activities in Guam” is safety. Observing basic rules greatly extends enjoyment and significantly reduces risk.

Avoid reef channels and areas with foaming waves
Avoid swimming alone; maintain a buddy system with at least two people
Absolutely wear a life jacket (especially for boat experiences, beginners, children)
No immediate entry after vigorous exercise; take ample rest
Sunbathing rule (30-40 minutes swim and 15 minutes shade break) to prevent exhaustion

Note

Even without rain forecasts, sudden showers can occur. With abrupt rain and wind, visibility and water temperature can drop, so if you sense weather changes, return to a safe zone immediately.

Equipment

Both renting locally and bringing personal gear have their pros and cons regarding “Water Activities in Guam.” Personal gear fits well, is hygienic, and can be used immediately without waiting. However, local rentals can decrease luggage weight, and it is easy to replace if broken. Anti-fogging treatments on snorkel masks are handy, and fins (flippers) aren’t necessary in shallow bays with weak currents but significantly boost swimming efficiency.

Recommendation

If you’re with family and children, having a separate snorkel vest (aids buoyancy for snorkeling) is less tiring at the surface with better mobility and satisfaction compared to waist belt-type life jackets.

Meals

Replenishing fluids and electrolytes before and after water activities is crucial. Tumon center has convenience stores (like ABC Stores) within walking distance, making it easy to grab quick snacks, water, and fruits. It’s efficient to enjoy poké, fish tacos, or simple grilled menus at casual beachfront restaurants and then return to water activities. Avoid overeating right before swimming, and maintain a balanced intake of proteins and carbohydrates for sustained energy in the afternoon.

Tip

Keeping water, ion drinks, and simple snacks in a cooler bag helps reduce trips on the beach and saves your budget. However, be sure to follow the “Leave No Trace” principle and take your trash with you.

Budget

Based on conversion into Korean won, you can plan the budget for a 3-night, 4-day trip revolving around “Water Activities in Guam” conservatively within the following ranges (excluding flights, subject to currency/peak season variations).

Local transportation (airport-hotel round-trip, public/shuttle mixed): 20,000~70,000 KRW

Tip

When activities are bundled (combo), or through limited-time promotions, savings of 20,000~50,000 KRW per person are possible. Ensure you compare and select inclusive packages (pickup, photos, equipment, insurance) for cost-effective choices.

Accommodation

If prioritizing “Water Activities in Guam,” the resorts along Tumon Beach Line offer the best accessibility. Accommodations right on the beach allow for efficient use of time by moving in swimwear from your room for short durations. However, the costs tend to be relatively high, often with additional charges for taxes and service fees. Choosing accommodations a block behind the beach or in Tumon outskirts lowers prices but may require transportation like cars or shuttles for beach access.

Estimated lodging costs (converted to Korean won, per night): Mid-to-high Tumon beachfront 250,000~450,000 KRW, Mid Tumon vicinity 150,000~300,000 KRW level. For families, a resort with a water park broadens the scope of water fun.

Compare and Book Hotel Prices

Recommendation

If there are morning marine activities (boats, parasailing), a breakfast package-included accommodation is convenient, and if you spend much time at the beach, prioritize checking the swimming pool/shower facility conditions and towel provision policies.

Transportation

Rental cars provide the most freedom in Guam. It’s recommended to bring a Korean driver’s license, an international driving permit, and a credit card in your name. However, if you’re primarily staying near Tumon for “Water Activities in Guam,” airport-hotel round-trip pickups and combinations of shuttles/taxis can suffice. There are commercial shuttle routes (linked with shopping malls) operating between Tumon and Tamuning and beach park parking is usually easy to use.

While driving, remember to observe speed limits, prioritize pedestrians, and slow down when it rains. Do not leave valuables in the vehicle at beach parks. Also, secure groceries immediately by dropping them off at your accommodation after shopping.

Airport

With a short distance between the airport and hotels, arranging pickup services is convenient even for late-night arrivals or early departures. If you have heavy equipment or are traveling with children, the loading/unloading stress is significantly reduced.

Book Airport Pick-Up

Tip

If you’re heading directly to the beach right upon arrival, pack swimwear and a change of clothes separately in your carry-on. You can start your “Water Activities in Guam” immediately after storing your luggage.

Checklist

Pre-entry 5-minute stretching, adapt to earplugs, swim cap, goggles
Essentials in the waterproof pack: hotel room key, small cash, phone
Check local weather/tide: schedule mainly for morning clear weather
Sunburn care: reapply SPF, prepare towels, cool water
Environmental protection: no coral contact, take your trash back
