Palau
Located in the far-flung reaches of the western Pacific Ocean, Palau is a remote island chain comprising around 500 distinct landmasses. Verdant jungles cloak the interiors of the islands, concealing hidden waterfalls and moss-covered rock formations, while towering stone monoliths stand as silent remnants of Palau's cultural heritage.
Underwater, the real magic of this Pacific paradise reveals itself. With its turquoise lagoons, crystalline waters and vibrant coral reefs, Palau boasts truly surreal and otherworldly underwater landscapes. Its signature blue holes, dramatic drop-offs, mysterious caverns and winding channels create an aquatic playground that continually captivates and thrills.
With over 1400 species of coral and around 500 fish species, Palau’s marine diversity is truly staggering. From whale sharks to elusive hammerheads and graceful manta rays, divers are consistently awestruck by the archipelago’s sheer abundance and variety of pelagic creatures. For in-the-know scuba enthusiasts, Palau has cemented its status as one of the best places to dive in Micronesia.
Best time to dive in Palau
Scuba diving in Palau can be enjoyed year-round, but the optimal time to visit is during the dry season from October through May. During these months, the water temperatures are delightfully warm, typically ranging between 27 and 30°C (81 and86°F). A lightweight 3mm wetsuit is more than sufficient for all-day diving. What truly sets Palau apart, however, is its exceptional underwater visibility, which is quite unusual for a location with nutrient-rich waters and strong ocean currents.
Best eco-friendly dive resort in Palau
Nestled among 64 acres of lush tropical gardens, the Palau Pacific Resort seamlessly blends luxury accommodations with the natural beauty of its stunning island setting. It features 160 unique guest rooms, suites and overwater bungalows, with none of its buildings taller than the tallest coconut tree to ensure a low-impact experience.
While staying at this Palau dive resort, guests can indulge in the serene spa, the stunning infinity pool and the large hot tub, which overlooks the sparkling waters of the Pacific Ocean. When hunger strikes, the resort's acclaimed restaurant serves up mouthwatering regional cuisine that highlights the fresh, locally sourced ingredients of Palau.
This luxury Palau resort is not only a stunning oasis of relaxation but also a primary supporter of conservation efforts to protect the island's biodiversity. It overlooks a marine sanctuary established by Koror State Law in 2002, which encompasses a fringing reef that’s home to several endangered species.
Recognising Palau's frequent water shortages, the resort has taken measures to ensure a sustainable water supply, drawing from its own rainwater catchment system and deep wells. Additionally, this eco-friendly Palau resort has invested in solar power generation and an innovative plastic-to-oil conversion system that transforms discarded plastic into fuel for its operations.

Kosrae
Tucked away in the vast expanse of the Pacific Ocean, the remote island of Kosrae remains a well-kept diving secret. This small landmass has been affectionately described as an “undeveloped Tahiti” - Kosrae really is a paradise on Earth!
Despite its diminutive size (Kosrae spans just 12 kilometres at its furthest points), the island’s underwater realm is nothing short of captivating. The sloping benthic environment is draped in a diverse tapestry of coral growth, with nearly every inch blanketed in vibrant displays.
Amidst this lush seascape, a sprinkling of anemones provides the island's most reliable and enchanting attraction - the captivating clownfish. Three species in particular - the tomato clownfish, Clark's clownfish and pink clownfish - can be reliably spotted on almost every dive and make for stunning photographic subjects.
But the wonders of Kosrae's underwater world don't end there. Venturing a bit deeper, divers may encounter the graceful, undulating forms of crinoids swaying in the current or catch a glimpse of the giant Pacific grouper prowling the reef. And for those with a keen eye and a bit of luck, the shallows may reveal the presence of blacktip reef sharks patrolling the edge of visibility or grey reef sharks playing in the current.
Best time to dive in Kosrae
The water temperature around the island remains remarkably consistent, holding steady at a comfortable 28°C (82°F) year-round. During the summer months from June through October, the ocean is generally calmer and the currents more gentle, making for easy, relaxed dives. In contrast, the winter season from late November to May can bring increased wind and stronger ocean currents, especially along the southern and western sides of the island. While these conditions may limit accessibility to some dive sites, they also attract larger pelagic species like sharks, manta rays and schools of migratory fish that are drawn to the nutrient-rich currents.
Best dive resort in Kosrae
Featuring just 18 rooms, this intimate Kosrae dive resort is the perfect base for a Micronesia diving vacation. It lies amidst verdant gardens and is staffed by friendly, attentive faces dedicated to ensuring your needs are met. Each of the air-conditioned rooms is outfitted with two double beds (making them ideal for couples or dive buddies), as well as TVs, minibars and tea and coffee-making facilities.
When you're not out diving, you can take advantage of the resort's full-service restaurant and bar or enjoy a refreshing dip in the sparkling swimming pool. This isolated island paradise is committed to sustainable practices, recently installing a 40 kilowatt (160 panel) solar system in addition to their existing solar water heaters.
But the real star of the show at Kosrae Nautilus Resort is the underwater environment and the property's experienced divemasters cater to guests’ every need. Additionally, this Kosrae dive resort is located on the island's sheltered side, providing a welcome respite from the trade winds.
“The resort is located right next to the ocean and the town of Lelu. The owner is able to provide information and arrange various types of activities…I have found Nautilus resort to be a great place to spend some time and am already looking forward to the next time.” - Georg (read more reviews here)

Guam
Guam is the largest island in the Mariana Island Chain and the only U.S. territory in Micronesia. It’s located just south of the Mariana Trench, the deepest point in the world's oceans, and was formed millions of years ago by the fusion of two ancient volcanoes that have since sunk beneath the waves.
Surrounding the island is a vast coral reef table, interrupted by deep water channels that allow access to the stunningly clear, blue waters for which the area is renowned. Along the coastline, rugged cliffs give way to lush mangrove forests and pristine sandy beaches, while the island's interior is dominated by high volcanic mountains, cascading waterfalls and traditional villages.
Underwater, Guam is a diver's dream, with over 75 easily accessible dive sites catering to all skill levels, from boat and beach dives to exhilarating drift dives. Boasting over 200 species of coral and an abundance of marine life, the exceptional diving here is complemented by warm water temperatures and incredible visibility.
Whether you're exploring the historic shipwrecks and aircraft in Apra Harbour or marvelling at the sheer walls and abundant pelagic life just offshore, Guam's crystal-clear waters and captivating natural beauty make it one of the best places to dive in Micronesia.
Best time to dive in Guam
Guam’s tropical climate is characterised by warm, balmy weather, with average temperatures hovering around 28 to 29°C (82 to 84°F) throughout the year. While the calmest conditions are experienced from late April to August, the windiest time in Guam is usually between January and early April. That being said, the majority of the prime dive sites are located on the leeward, or western, side of the island and protected from the full force of the winds. Water temperatures remain relatively consistent throughout the year at 28°C (82°F).

Yap
Comprising four islands encircled by a coral reef, Yap is a unique destination in that it was formed by an uplifted portion of the ancient Asian Continental Shelf. Surrounded by a broad, shallow lagoon, its coastlines are characterised by lush mangrove forests while the interiors feature rolling hills blanketed in thick, jungle-like vegetation.
Yap's most famous and iconic marine residents are the hundreds of manta rays that call the surrounding waters “home”. During the mating season between December and late April, these gentle ocean giants congregate in truly breathtaking numbers, with processions of up to a dozen mantas at a time gracefully cruising back and forth through the channels. Not to miss is the "Valley of the Rays" where visitors can witness the magnificent spectacle of these mantas (some with wingspans up to 4 metres wide) gliding effortlessly around cleaning stations.
Aside from its manta ray encounters, Yap boasts a diverse array of underwater environments, from dramatic drop-offs to gentle sloping reefs and thrilling channel drifts. It’s a paradise for underwater photographers, videographers and adventurous divers of all skill levels. Additionally, there’s the unique opportunity to witness the captivating courtship displays of the mandarin fish.
Best time to dive in Yap
Yap experiences consistently warm and humid conditions that allow for year-round diving and underwater exploration. Average daytime temperatures hover around 30°C (86°F) while the ocean waters maintain an average temperature of 28°C (82°F). This subtropical climate is characterised by two distinct seasons - the northeast trade wind months from November to May and the calmer summer months from June through October.

Pohnpei
Pohnpei is a mountainous island oasis that boasts an abundance of natural wonders and cultural treasures. Situated roughly halfway between Hawaii and the island of Guam, this verdant landmass is home to the capital of the Federated States of Micronesia, the friendly city of Palikir.
Pohnpei rises dramatically from the surrounding ocean, with its jungle-clad interior crowned by some of the highest peaks in the entire region. The island’s abundant rainfall feeds a network of more than 40 rivers that cascade down from the mountains through the island's interior, forming countless waterfalls and freshwater swimming holes.
This nutrient-rich ecosystem has created a flourishing environment of tropical forests and floral diversity, earning Pohnpei the moniker of the "Garden Island." Along the coast, these waterways have also given rise to thriving mangrove forests that provide a crucial habitat for juvenile marine life, which attracts a wide variety of larger pelagic species to the island's offshore waters.
Pohnpei is renowned for its incredibly healthy and diverse underwater ecosystems, protected by a barrier reef surrounding the island. Beneath the waves, divers and snorkellers can encounter a dazzling array of marine life, from eagle rays and tuna to barracuda, sharks and a kaleidoscope of brightly-coloured reef fish. Perhaps the crown jewel of Pohnpei's underwater world, however, are the island's resident manta rays, which can be spotted on a near-daily basis.
Beyond the island's natural wonders, Pohnpei also boasts a wealth of ancient cultural treasures, most notably the awe-inspiring ruins of Nan Madol on the island's eastern coast. This sprawling archaeological site features a network of man-made islands, basalt temples and burial vaults that stand as a testament to the ingenuity and sophistication of Pohnpei's long-ago inhabitants.
Best time to dive in Pohnpei
Pohnpei is renowned for its tropical climate that remains consistently warm and wet throughout the year and with temperatures hovering around 30°C (86°F). While the island experiences rainfall in abundance, the months of January and February tend to see a slight reduction in precipitation. The island's tropical climate is further shaped by the predictable trade wind patterns that blow across the region, typically from December to March. Regardless of the time of year, the surrounding waters maintain a consistently comfortable temperature of around 27°C (80°F).
Best dive resort in Pohnpei
Conveniently located just a 10-minute car ride from the airport, this beloved Pohnpei dive resort is home to the Pohnpei Surf Club - a home base for adventure seekers from near and far.

Centrally situated, it’s just a stone's throw from an abundance of bars, restaurants and local markets, making it an ideal setting for a Pohnpei dive vacation.

Chuuk
Formerly known as Truk, this cluster of 16 volcanic islands comprises one of the Federated States of Micronesia’s four states. Amongst divers, it’s most famed for the Truk Lagoon, which is the final resting place for an astounding array of World War II wrecks.
This natural harbour served as the headquarters of the Japanese Imperial Fleet between 1914 and 1945. Today, it is home to more than 70 ships, planes and submarines that were sunk during a 1944 aerial attack by Allied carrier planes, resulting in the most significant naval loss in history.
The atoll’s outer barrier reef is dotted with palm-fringed sand spits that give way to diverse marine ecosystems while the central lagoon is dominated by volcanic islands that rise dramatically from the fantastically blue waters. While many of the wrecks are only accessible to technical divers due to their depth, there are also numerous shallower sites that are suitable for open-water divers and even snorkellers.
The main island of Weno serves as the commercial and population centre of the region, with hotels catering to the divers and tourists who flock to this underwater museum.
Best time to dive in Chuuk
As with all of Micronesia, Chuuk experiences a tropical climate, with a distinct rainy season stretching from April through December. The rest of the year is relatively dry, ushering in a welcome respite from the heavier rains. Regardless of the season, the water temperatures in Truk Lagoon remain pleasantly warm, typically ranging between 27°C and 30°C (80°F and 86°F), allowing divers to comfortably explore the depths while outfitted in a 3mm wetsuit.
Best dive resort in Chuuk
Located on one of Micronesia’s most naturally breathtaking peninsulas, the Blue Lagoon Resort and Spa lies at the southwestern tip of Weno Island. This stunning property is surrounded by towering coconut palms while the well-manicured grounds house a variety of amenities designed to help visitors fully immerse themselves in the ultimate island getaway experience.
Guests can indulge in pampering treatments at the on-site spa or enjoy a relaxing drink at the famous Sunset Bar. Newly renovated rooms and a full-service dining room serving both international and local cuisine round out the offerings.
Conveniently located on the resort’s grounds is the Blue Lagoon Dive Shop, which offers daily diving and snorkelling excursions to the Truk Lagoon’s most famed wreck sites. Kayaks and standup paddleboards are also available for rent.
How to get to Micronesia
When planning a dive vacation in Micronesia, the most convenient and well-connected airport is Antonio B. Won Pat International Airport in Guam. This major hub receives numerous international flights from all over the world, including the United States, Japan, China and South Korea.
Alternatively, Roman Tmetuchl International Airport in Palau receives flights from select destinations and can serve as an alternative entry point, particularly for those wishing to focus their travels on the island nation of Palau. Similarly, the Yap and Chuuk International Airports, located in their respective Micronesian states, offer more localised connections and may be preferable for travellers with a specific interest in those regions.
Navigating the Micronesian archipelago is made easy by the extensive flight network of Continental Air Micronesia. Their renowned "Island Hopper" service connects Guam to Hawaii, with stops along the way at various Micronesian hubs like Majuro, Kwajalein, Kosrae, Pohnpei and Chuuk. Additionally, Continental Air Micronesia offers another route linking Guam to Manila, with stops in Yap and Palau.
For those looking to reach Micronesia from other parts of the world, there are several viable options. Nauru Airlines and Fiji Airways both operate flights from Fiji to Tarawa, the capital of Kiribati, while Continental Airlines can transport travellers directly from the continental United States to Guam. Nauru Airlines also offers connections from Brisbane and Fiji to Nauru and Tarawa.
