Route Description - Palau Islands

Blue Corner consistently ranks among the world’s top dive sites and is renowned among scuba divers globally. Yet beyond this iconic location, Palau boasts a vast array of equally thrilling, world-class dive sites. The region is essentially a shallow turquoise lagoon encircled by dramatic drop-offs into the Pacific Ocean. Nutrient-rich currents flowing into these shallows create a vibrant marine environment where corals and schooling fish compete for space. Adding to the allure are the channels that feed into the lagoon, attracting numerous manta rays and reef sharks—a true paradise for scuba enthusiasts.

A liveaboard diving expedition through the Palau Islands offers a rich variety of experiences, from reef and drift dives to sunset and night explorations. As the entire nation is designated a shark sanctuary, divers are treated to regular sightings of reef sharks and manta rays. The underwater landscape also features stunning hard coral reefs, caves, caverns, a wreck, and the famous channel diving for which Palau is celebrated. While many sites are suitable for divers of all levels, some channels feature strong currents, making reef hooks an essential part of dive gear.

The diving itineraries focus on the Rock Islands Southern Lagoon, a UNESCO World Heritage Site, with an additional day spent exploring Peleliu. The islands' narrow channels and ever-changing tidal currents are best navigated using skiff tenders. All liveaboards operating in Palau, including the Palau Siren, are required to anchor in designated mooring areas around the Rock Islands. As such, movement of the main vessel within the lagoon is minimal, with dive groups typically dropped off and retrieved by skiffs. These transfers between the Palau Siren and the dive sites generally take between 5 to 15 minutes, depending on anchorage.

Embarking from Malakal Harbour, the Palau Siren cruises into the Rock Islands Southern Lagoon before proceeding to Peleliu. Dive site selection and sequence vary by trip and are tailored to current conditions, ensuring guests experience the best of Palau’s three premier dive regions: Ulong, Ngemelis, and Peleliu.

A typical day aboard offers up to four dives—three during the day and, where possible, a sunset or night dive. The daily schedule is designed to balance activity and relaxation:

Light breakfast followed by a briefing and Dive 1
Full breakfast, relaxation, briefing, and Dive 2
Lunch, relaxation, briefing, and Dive 3
Snack, relaxation, briefing, and Dive 4
Dinner

*On days when land excursions are offered, only three dives are conducted.

Route Description - New Moon Spawning (10 nights)

The 10-night Special New Moon Spawning liveaboard itinerary aboard the Palau Siren offers divers a truly extraordinary experience. This unique voyage is designed to coincide with one of nature’s most impressive underwater phenomena: the mass spawning aggregation of bumphead parrotfish (Bolbometopon muricatum) during the new moon lunar cycle. On these special departures, guests have the rare opportunity to witness thousands of these large reef fish congregating in a single area of Palau to reproduce—a breathtaking display of synchronized marine life behavior.

During this period, the Cruise Director provides a series of informative briefings and presentations, offering insights into the spawning event and what divers can expect to see. These dives, while thrilling, are recommended only for experienced divers due to the strong currents commonly found at these sites.

The majority of the diving takes place within the Rock Islands Southern Lagoon—a UNESCO World Heritage Site—with an additional day spent exploring the waters around Peleliu. Given the narrow channels and dynamic tidal flows of the area, skiff tenders are used to navigate between dive sites and the main vessel. Palau Siren, like all liveaboards in the region, is required to use designated mooring points scattered throughout the Rock Islands. As a result, cruising within the lagoon is minimal, with dive transfers typically lasting between 5 to 15 minutes depending on the anchorage location.

In addition to the spawning dives, certain itineraries include the option to participate in Blackwater diving—a surreal and adventurous experience that involves diving at night, often far from the reefs, to witness deep-sea creatures rising toward the surface to feed. These nocturnal dives offer a chance to observe rare and bioluminescent marine life in the open ocean.

Each day typically includes up to four dives: three daytime dives and either a sunrise, sunset, or night dive depending on the timing of the spawning activity. The daily schedule is structured as follows:

Light breakfast, followed by briefing and Dive 1
Full breakfast, relaxation, briefing, and Dive 2
Lunch, relaxation, briefing, and Dive 3
Snack, relaxation, briefing, and Dive 4 (where possible)
Dinner

*On days featuring land excursions, the number of dives may be limited to three.

Route Description - Full Moon Spawning (7 nights)

The 7-night Full Moon Spawning itinerary aboard the Palau Siren delivers an unforgettable liveaboard diving experience, combining Palau’s breathtaking dive sites with a chance to witness one of the ocean’s most thrilling natural phenomena—the mass spawning of red snapper (Lutjanus bohar) during the full moon. During this lunar phase, thousands of red snappers gather in a high-energy spectacle, drawing in large oceanic predators that prey on the swirling, spawning fish. This powerful underwater event is rarely seen by divers, making it a highlight of the Palau diving calendar.

As the full moon period approaches, the Cruise Director offers a series of informative briefings to help divers understand the unique behaviors and conditions surrounding these special dives. Given the strong currents typically present at the spawning sites, these dives are recommended for experienced divers only.

Most diving during this itinerary takes place within the Rock Islands Southern Lagoon, a UNESCO World Heritage Site, with one day spent exploring the waters near Peleliu. The narrow channels and shifting tides make certain parts of the lagoon best navigated by skiff tenders. In line with national regulations, Palau Siren—along with all other liveaboards operating in the area—is required to use specific anchorage and mooring points, which limits movement within the lagoon. Dive teams are dropped off and picked up by skiffs, with transfers between the main vessel and dive sites generally taking between 5 to 15 minutes depending on anchorage.

Beyond the red snapper spawning event, some itineraries also offer the chance to try Blackwater diving—a truly unique night dive experience. Divers descend into open ocean in total darkness, far from the reef, to witness deep-sea creatures rising to the surface to feed—revealing a hidden world of bizarre and bioluminescent marine life.

Each day typically includes up to four dives: three daytime dives and one sunrise, sunset, or night dive, depending on the timing of the spawning activity. The daily diving schedule is as follows:

Light breakfast, followed by briefing and Dive 1
Full breakfast, relaxation period, briefing and Dive 2
Lunch, relaxation period, briefing and Dive 3
Snack, relaxation period, briefing and Dive 4 (where possible)
Dinner

*On days that include land excursions, the number of dives is limited to three.

This unique voyage is designed to coincide with one of nature’s most impressive underwater phenomena: the mass spawning aggregation of bumphead parrotfish (Bolbometopon muricatum) during the new moon lunar cycle. On these special departures, guests have the rare opportunity to witness thousands of these large reef fish congregating in a single area of Palau to reproduce—a breathtaking display of synchronized marine life behavior.

During this period, the Cruise Director provides a series of informative briefings and presentations, offering insights into the spawning event and what divers can expect to see. These dives, while thrilling, are recommended only for experienced divers due to the strong currents commonly found at these sites.

The majority of the diving takes place within the Rock Islands Southern Lagoon—a UNESCO World Heritage Site—with an additional day spent exploring the waters around Peleliu. Given the narrow channels and dynamic tidal flows of the area, skiff tenders are used to navigate between dive sites and the main vessel. Palau Siren, like all liveaboards in the region, is required to use designated mooring points scattered throughout the Rock Islands. As a result, cruising within the lagoon is minimal, with dive transfers typically lasting between 5 to 15 minutes depending on the anchorage location.

In addition to the spawning dives, certain itineraries include the option to participate in Blackwater diving—a surreal and adventurous experience that involves diving at night, often far from the reefs, to witness deep-sea creatures rising toward the surface to feed. These nocturnal dives offer a chance to observe rare and bioluminescent marine life in the open ocean.

Each day typically includes up to four dives: three daytime dives and either a sunrise, sunset, or night dive depending on the timing of the spawning activity. The daily schedule is structured as follows:

Light breakfast, followed by briefing and Dive 1
Full breakfast, relaxation, briefing, and Dive 2
Lunch, relaxation, briefing, and Dive 3
Snack, relaxation, briefing, and Dive 4 (where possible)
Dinner

*On days featuring land excursions, the number of dives may be limited to three.

Route Description - Palau Islands

Blue Corner consistently ranks among the world’s top dive sites and is renowned among scuba divers globally. Yet beyond this iconic location, Palau boasts a vast array of equally thrilling, world-class dive sites. The region is essentially a shallow turquoise lagoon encircled by dramatic drop-offs into the Pacific Ocean. Nutrient-rich currents flowing into these shallows create a vibrant marine environment where corals and schooling fish compete for space. Adding to the allure are the channels that feed into the lagoon, attracting numerous manta rays and reef sharks—a true paradise for scuba enthusiasts.

A liveaboard diving expedition through the Palau Islands offers a rich variety of experiences, from reef and drift dives to sunset and night explorations. As the entire nation is designated a shark sanctuary, divers are treated to regular sightings of reef sharks and manta rays. The underwater landscape also features stunning hard coral reefs, caves, caverns, a wreck, and the famous channel diving for which Palau is celebrated. While many sites are suitable for divers of all levels, some channels feature strong currents, making reef hooks an essential part of dive gear.

The diving itineraries focus on the Rock Islands Southern Lagoon, a UNESCO World Heritage Site, with an additional day spent exploring Peleliu. The islands' narrow channels and ever-changing tidal currents are best navigated using skiff tenders. All liveaboards operating in Palau, including the Palau Siren, are required to anchor in designated mooring areas around the Rock Islands. As such, movement of the main vessel within the lagoon is minimal, with dive groups typically dropped off and retrieved by skiffs. These transfers between the Palau Siren and the dive sites generally take between 5 to 15 minutes, depending on anchorage.

Embarking from Malakal Harbour, the Palau Siren cruises into the Rock Islands Southern Lagoon before proceeding to Peleliu. Dive site selection and sequence vary by trip and are tailored to current conditions, ensuring guests experience the best of Palau’s three premier dive regions: Ulong, Ngemelis, and Peleliu.

A typical day aboard offers up to four dives—three during the day and, where possible, a sunset or night dive. The daily schedule is designed to balance activity and relaxation:

Route Description - Full Moon Spawning (7 nights)

The 7-night Full Moon Spawning itinerary aboard the Palau Siren delivers an unforgettable liveaboard diving experience, combining Palau’s breathtaking dive sites with a chance to witness one of the ocean’s most thrilling natural phenomena—the mass spawning of red snapper (Lutjanus bohar) during the full moon. During this lunar phase, thousands of red snappers gather in a high-energy spectacle, drawing in large oceanic predators that prey on the swirling, spawning fish. This powerful underwater event is rarely seen by divers, making it a highlight of the Palau diving calendar.

As the full moon period approaches, the Cruise Director offers a series of informative briefings to help divers understand the unique behaviors and conditions surrounding these special dives. Given the strong currents typically present at the spawning sites, these dives are recommended for experienced divers only.

Most diving during this itinerary takes place within the Rock Islands Southern Lagoon, a UNESCO World Heritage Site, with one day spent exploring the waters near Peleliu. The narrow channels and shifting tides make certain parts of the lagoon best navigated by skiff tenders. In line with national regulations, Palau Siren—along with all other liveaboards operating in the area—is required to use specific anchorage and mooring points, which limits movement within the lagoon. Dive teams are dropped off and picked up by skiffs, with transfers between the main vessel and dive sites generally taking between 5 to 15 minutes depending on anchorage.

Beyond the red snapper spawning event, some itineraries also offer the chance to try Blackwater diving—a truly unique night dive experience. Divers descend into open ocean in total darkness, far from the reef, to witness deep-sea creatures rising to the surface to feed—revealing a hidden world of bizarre and bioluminescent marine life.

Each day typically includes up to four dives: three daytime dives and one sunrise, sunset, or night dive, depending on the timing of the spawning activity. The daily diving schedule is as follows:

Light breakfast, followed by briefing and Dive 1
Full breakfast, relaxation period, briefing and Dive 2
Lunch, relaxation period, briefing and Dive 3
Snack, relaxation period, briefing and Dive 4 (where possible)
Dinner
