Scuba Diving in Palau
Walls, Currents, and Stingless Jellyfish in the Heart of Micronesia
Palau is a legendary scuba diving destination in the western Pacific, an archipelago of more than 500 islands scattered across a turquoise lagoon and fringed by some of the most dramatic walls, channels, and blue holes on Earth. The country is best known for its electrifying drift dives where nutrient-rich currents funnel grey reef sharks, whtip sharks, and schooling jacks past vertical drop-offs, and for the German Channel where manta rays queue at cleaning stations. Beyond the adrenaline, Palau offers pristine hard and soft coral gardens, a remarkable collection of WWII wrecks resting in calm bays, and the surreal Jellyfish Lake, where millions of stingless golden jellyfish pulse through land-locked water. The Palau Protected Areas Network safeguards a huge share of the reef, which helps keep visibility routinely above 30 metres and fish life abundant. Whether you are a wide-angle photographer chasing pelagics, a macro hunter combing sheltered bays for ghost pipefish and frogfish, or a beginner exploring shallow coral gardens, Palau delivers a complete and world-class underwater experience wrapped in warm Micronesian hospitality.

Practical Information
Arrival & Entry
Getting Around
Almost all diving is reached by boat from Koror, with day trips and liveaboards covering the Rock Islands, Peleliu, and Kayangel. On land, taxis and rental cars connect Koror to the airport on Babeldaob via the compact compact road network. Inter-island travel to Kayangel and Peleliu is by speedboat or liveaboard.
Safety & Culture
Common Scams
- Unlicensed 'guides' offering cheap boat trips at the dock; always book through a registered dive operator.
- Overpriced souvenirs marketed as 'authentic' near cruise-ship stops.
- Currency confusion with taxi drivers; agree on a fare before boarding.
Cultural Etiquette
- Palauans are deeply respectful of their land and sea; ask permission before entering villages or private beaches.
- Modest dress is appreciated when away from resorts, and removing hats indoors is a polite gesture.
Health & Safety Advice
Essential tips for a safe trip
Travel Essentials
Palauan and English are the official languages, and English is widely spoken across Koror, the resorts, and all dive operations, making Palau very easy for English-speaking travellers to navigate. Many older Palauans also speak Japanese, a legacy of the wartime period.
Tap water in Palau is generally not considered safe to drink; visitors should stick to bottled or filtered water, which is supplied by most hotels and liveaboards. Ice at reputable resorts is usually made from treated water.
The US Dollar (USD) is the official currency and is used everywhere, from high-end resorts to local markets. Credit cards are accepted at major dive operators and hotels, but carry cash for small purchases, taxis, and village visits.
Citizens of the United States, most EU countries, Japan, Taiwan, and many others may enter Palau visa-free for up to 30 days, while US citizens may stay up to one year. All visitors must pay a departure/eco-tax on leaving. A valid passport with at least six months' validity is required, and proof of onward travel is routinely requested by airlines.

Historical Context
Palau's human history stretches back more than 3,000 years to the arrival of Austronesian voyagers who built the famous stone megalithic 'bai' meeting houses and terraced hillside gardens that still dot Babeldaob. The islands developed a sophisticated matrilineal society organised into clans and villages, with a rich oral tradition and skilled navigators who traded across the Caroline Islands. Spanish explorers arrived in the 16th century, and Palau was later claimed by Spain, then sold to Germany in 1899, followed by Japanese administration after World War I. During World War II, Palau was a major Imperial Japanese base, and the fierce Battle of Peleliu in 1944 left a legacy of wrecks and artefacts that divers explore today. After the war, Palau was administered by the United States under a UN trusteeship until it achieved independence in 1994, entering a Compact of Free Association with the US. Modern Palau is proud of its conservation leadership, most visibly through the Palau Protected Areas Network and the world's first 'shark sanctuary'.
Geography & Nature
Palau is an island nation in the western Caroline Islands of Micronesia, centred near 7.5 degrees north latitude and 134.5 degrees east longitude. The country comprises the main volcanic island of Babeldaob, the limestone Rock Islands (Chelbacheb) with their iconic mushroom-shaped islets, the raised coral island of Peleliu, the remote atoll of Kayangel to the north, and the southwestern island of Angaur. The capital, Ngerulmud, sits on Babeldaob, while the commercial centre of Koror connects the islands via the long Koror-Babeldaob Bridge. Surrounding the islands is a vast lagoon protected by a continuous barrier reef, producing dramatic walls that plunge into the Philippine Sea and a labyrinth of channels that funnel powerful currents. This geology creates the perfect recipe for Palau's signature wall, drift, and blue-hole diving, as well as its unique marine lakes.
Climate & Weather
Palau has a tropical rainforest climate with warm temperatures and high humidity year-round, averaging between 27 and 31 degrees Celsius both in the air and in the sea. There is no true cold season; instead the year divides into a drier period from roughly November to April and a wetter, occasionally typhoon-affected period from July to October, with May, June, and October acting as transition months. Water temperatures stay between 27 and 30 degrees Celsius, so a 3 mm wetsuit is usually plenty. Rain falls mostly in short, heavy bursts rather than all-day deluges, and even in the wet season divers can usually find calm, sheltered sites. The consistency of the climate is one reason Palau is considered a superb twelve-month diving destination, with the dry season simply offering the calmest seas and clearest water.
People & Culture
Palauans are known for their warmth, dignity, and deep connection to both land and sea, and visitors are often struck by the quiet pride they take in their culture and environment. Society is organised around matrilineal clans, and traditional leadership, storytelling, and dance remain important parts of community life. The population is small, around 18,000 people, with most living on Koror and Babeldaob, and a strong sense of stewardship over the reefs that sustain them. Palauans blend modern life with tradition effortlessly, and the national 'Pledge' that visitors recite on arrival reflects a genuine collective commitment to protecting the ocean. Despite the challenges of isolation and a small economy, Palauans are resilient, hospitable, and famously welcoming to divers who come to enjoy their underwater heritage.
Local Languages
The official languages of Palau are Palauan and English, and English is used throughout government, education, and tourism, so travellers rarely face a language barrier. Palauan is an Austronesian language with several regional dialects, and many Palauans also speak Japanese from the colonial era. Learning a few phrases such as 'Alii' (hello) and 'Kom kmal mesaul' (thank you) is warmly appreciated. Signage, menus, and dive briefings are almost always provided in English.
Gastronomy
Palauan cuisine makes the most of the surrounding ocean and tropical gardens, built around fresh fish, shellfish, taro, cassava, and coconut. A staple is 'ukoy', a crispy taro-leaf and seafood pancake, alongside fresh tuna sashimi, grilled octopus, and coconut-milk curries that show the islands' Asian and Pacific influences. Local favourites include fruit bat soup (a traditional delicacy) and 'tamarind' prawns, while imported staples such as rice and noodles round out everyday meals. Western and Japanese restaurants are plentiful in Koror, catering to divers, but trying a local 'small island' eatery is well worth it. Fresh tropical fruit such as papaya, pineapple, and mango is abundant, and the coffee and baked goods at Koror cafes make a fine start to a diving day.

Frequently Asked Questions
Q:Do I need to be an advanced diver to enjoy Palau?
Not at all. While sites like Blue Corner and Peleliu Express demand advanced certification and drift experience, Palau also offers gentle coral gardens, calm lagoons, and shallow wrecks that are perfect for beginners and snorkellers. Most operators run a check-out dive to place you on suitable sites.
Q:When is the best time to see manta rays in Palau?
Manta rays visit the German Channel cleaning stations throughout the year, with particularly reliable sightings during the calmer dry season from November to April. Peleliu Corner can also produce mantas, and occasional sightings occur along the outer walls.
Q:Is Palau good for macro photography as well as big animals?
Yes. Sheltered bays such as Nikko Bay and sites like Carp Island and Disneyland are macro havens for ghost pipefish, frogfish, seahorses, and nudibranchs, while the walls and channels deliver world-class wide-angle pelagic action. Many divers bring both macro and wide-angle rigs.
Q:Can I dive the WWII wrecks without advanced certification?
Several wrecks, including the Jake Seaplane and Helmet Wreck, sit in shallow, calm water and are suitable for open-water divers, while deeper vessels like the Iro Maru require advanced certification for penetration. Always follow your guide's depth and penetration limits.
Q:Is it true you cannot scuba dive Jellyfish Lake?
Correct. Jellyfish Lake is a protected marine lake where scuba is prohibited to preserve the delicate ecosystem; visitors snorkel among the stingless golden jellyfish. The experience is unique and family-friendly, and several other marine lakes offer similar snorkelling.
Q:How safe is diving in Palau regarding emergencies?
Palau has a functioning hyperbaric chamber at Belau National Hospital in Koror, and the established dive operators maintain strict protocols, log dives, and coordinate with the chamber. As always, dive within your limits, ascend slowly, and carry appropriate insurance such as DAN.
