[2025 Santa Rita ] Travel Guide for Blue Hole (Updated Apr)

Hey friends, are you ready for a thrilling diving adventure in 2025? Today, we'll provide you with a diving guide to Guam, allowing you to easily check off four legendary dive sites from your bucket list! Four Legendary Dive Sites You Must Explore 1. Tumon Bay: Located in the southwest of Guam, this is a glass-like sea with over 30m visibility, a coral garden perfect for beginners. Kneel on the white sand and watch the swirling schools of jackfish, clownfish darting among purple staghorn corals, and sunlight piercing the water's surface. It's like falling into liquid crystal, breathtakingly beautiful! 2. Blue Hole: Located in the northeast of Guam, this is a 30m deep vertical shaft cave. When the light beams penetrate the seawater, the magical scene is simply stunning! However, you'll need an AOW certificate or higher to dive here, and it's recommended to bring a diving flashlight to explore the mysterious blue hole. 3. Tokai Maru (WWII Shipwreck): Located off the coast of Apra Harbor, you can dive with the wreckage of a 1917 German freighter. Soft corals bloom on the rusting metal, creating a scene rich with history. Capture silhouette shots as you swim out of the cabin windows for amazing photos! 4. Shark's Hole: Located near Piti Bay, this is where unforgettable moments are made! Be surrounded by more than 20 blacktip reef sharks. While your heart might race, the safety level is MAX, making it a true adventurer's game! 2025 Latest Precautions 1. Updated Diving Policies: All divers must carry an electronic dive log, and some dive shops require diving records from the past three months. Applying sunscreen before entering the water is prohibited. It is recommended to wear a sun-protective rash guard to protect the marine environment. 2. Safety Precautions: In areas with strong rip currents, stay close to your dive guide and be wary of this hidden danger. You can carry a dive slate and compass for underwater navigation. However, drift diving is prohibited at some dive sites, so please be aware. 3. Environmental Protection: Participate in coral planting projects to receive a $5 discount on diving fees. It's a way to protect the environment and save money. Remember to book in advance. Money-Saving Tips for Budget Travelers 1. Flights: The secret to round-trip flights from Shanghai/Beijing to Guam with taxes included for 2k+ is to keep an eye out for United Airlines' March promotion (2025.3.1-3.15). Choosing a connecting flight via Korea/Japan can save you an additional 500 yuan, but you'll need a transit visa. 2. Accommodation: 200 yuan/night per person is achievable! Guesthouses in the Tumon area are 40% cheaper than hotels. We recommend "Aqua Guesthouse," which is a 5-minute walk from the beach, super convenient. Stay for 7 consecutive nights and get a free boat dive, what a deal! 3. Diving: For equipment rental, you can bring your own mask and snorkel and rent a BCD and regulator, saving $15 per day. We recommend "Dive Guam," which has Chinese-speaking dive guides and offers a "buy 5 get 1 free" deal during the off-season. Go for it! Friends, actions speak louder than words. Let's embark on a fantastic diving journey to Guam in 2025! Remember to save this guide. We hope everyone has an unforgettable diving experience!

Guam Blue Hole: Dive into the Heart of the Pacific's Enchanting Deep Blue Before You Go: This is Not an Ordinary Dive The Blue Hole in Guam is known as the "Blue Tears of the Pacific" among divers worldwide, but its uniqueness goes beyond just being a popular photo spot. This vertical sea cave, formed by ancient volcanic activity, hides three mysterious exits: one leading to a 40-meter-deep blue abyss, another connecting to a colorful tunnel of coral gardens, and the third leading to a rarely visited "secret cave." Visiting in February offers the best visibility of up to 50 meters and a constant water temperature of around 28°C, making it the perfect time to avoid the typhoon season. Exclusive Tip: Contact local Chamorro native dive guides in advance, as they hold the ancient knowledge of tides and light. From 10:15 to 11:30 every day, sunlight penetrates the cave roof at a specific angle, casting a changing blue spectrum on the cave floor. This is the "Blue Hole Moment" that even Google Maps won't tell you about. --- Equipment Revolution: Beyond Conventional Diving Experience Forget about heavy traditional equipment. In Guam, dive shops are now offering "freediving + underwater photography" combo packages. In the mid-water of the Blue Hole (12-18 meters), it's recommended to switch to fish-tail fins. As you swim among the stalactites, professional photographers will capture magical images of you dancing with schools of jackfish using wide-angle lenses. A dive shop called "Siren's Eye" even offers special night diving equipment: fluorescent diving suits paired with bioluminescent bracelets, allowing you to create an underwater aurora with glowing plankton in the dark. Fun Fact: The bottom of the Blue Hole is covered with special minerals. Shine a UV flashlight on the rock walls, and you'll see the original ocean totems left by the ancient Chamorro people. --- In-Depth Experience: Redefining "Diving Travel" 1. Cave Breakfast Ceremony Follow the dive guide at 5 am to kayak into the cave entrance. Enjoy a "Chamorro Breakfast Basket" while snorkeling at dawn: coconut milk red rice kept warm with volcanic stones, grilled fish wrapped in banana leaves, and a refreshing drink made with sea grapes. 2. Sonar Meditation Experience The Blue Hole Sound Therapy Studio offers underwater sound therapy: wear special bone conduction headphones and listen to a mix of Chamorro warship drums and humpback whale songs at a depth of 15 meters in the cave. Combine this with specific frequency sound wave vibrations for underwater meditation. 3. Geological Time Capsule Bring a mini 3D scanner (available for rent at dive shops) to record the symbiotic wonders of volcanic glass and coral fossils from 2 million years ago in the Blue Hole rock layers. Create your own "Geological NFT Commemorative Card." --- Blue Continuation on Land 1. Chamorro Dye Workshop Use special seaweed collected from the Blue Hole to make Triton's Blue dye. Print the outlines of marine life seen during your dive on traditional fabric. Local artisans will teach you how to polish the fabric with giant clam shells for a shimmering effect. 2. Cave Echo Bar Visit the Tumon Bay Echo Bar, built in a cliff cave above the Blue Hole. Order a "Deep Abyss Margarita" made with blue curacao and sea salt. The LED light at the bottom of the glass will project real-time underwater images. 3. Custom Star Map Join the "Marine Astronomy Workshop" at the University of Guam. Overlay the Southern Hemisphere star map from the night of your dive with the Blue Hole sonar scan map to create a glow-in-the-dark star chart necklace. --- Safety and Environmental Protection: New Generation Adventure Rules - Beware of "Blue Hole Oxygen Intoxication": Stay at 5 meters for an extra 3 minutes during ascent for "color adaptation." Sudden exposure to strong light on land may cause temporary color vision distortion. - Bring edible coral restoration gel (made from coconut oil and limestone powder) and participate in cave wall ecological restoration under the guidance of an instructor. - Wear a sting-proof suit: February is the end of the box jellyfish migration season. A dive shop is experimenting with making natural repellents using turtle skin pheromones. --- Easter Egg Route: Secret Spots 99% of Tourists Don't Know After completing the Blue Hole's three-exit challenge, show your electronic badge to the dive guide to unlock a hidden route: swim about 80 meters out of the southeast cave and find the sunken Japanese cargo ship "Aoba Maru" behind the coral reef. On the deck of this ship, covered in soft corals, lies an unopened wooden box of sake. Take a small bottle in a waterproof bag and exchange it for a limited edition "Underwater Aged" cocktail at an izakaya in Tumon Bay. --- As the purple sunset paints the sea red, sitting on the natural stone chair on the Blue Hole cliff, you'll understand the true magic of this journey. It's not just about exploring the scars of the Earth but also opening a time portal to ancient ocean civilizations. Remember to stamp a shark tooth-shaped seal on your waterproof logbook. This is the ancient Chamorro blessing for the brave: May the sea always recognize your soul. Guam, USA
