This custom 10-night itinerary aboard the Rock Islands Aggressor is planned to coincide with a new moon, allowing us to dive a Bumphead Parrotfish spawning site. We conducted our first Field Survey in Palau in October 2016 and were astounded by the fish diversity, which included Reef Mantas visiting cleaning stations, huge schools of Unicornfish, and mating Mandarinfish. One of our most memorable dive locations from the first Palau REEF Trip included sightings of the rare Blueback Pygmy Angelfish, Harlequin Grouper, and Decorated and Helfrich's Dartfish. We look forward to returning during this special charter to see what other discoveries await.

Project Focus: This purpose of this trip is to conduct fish surveys to support REEF's Volunteer Fish Survey Project. Click here to learn more about participating in fish surveys on a REEF Field Survey Trip!

Best Suited For: Divers. Most diving in Palau is drift diving, so divers should be comfortable with a current.

Diving: Diving will be done from from a 35 ft. skiff that carries 18 divers, to allow for quick access a variety of dive sites. There will be 3-4 dives per day, and night dives will be offered on some nights of the charter, conditions permitting. Most diving in Palau is drift diving, so divers should be comfortable with a current. It is suggested that divers bring safety items such as a Dive Alert, Life Line and safety sausage.

REEF will receive a portion of the proceeds from travel insurance purchases when you click on the following affiliate links for DiveAssure or DAN.

How to Get There: Participants are responsible for booking flights to/from Koror International Airport (ROR). Due to the requirement for the day 4 COVID test, it is extremely important for everyone to arrive on the same flight so the day 4 testing schedules are the same, or arrive in Palau early enough to complete the day 4 testing prior to boarding. Flight schedules are subject to change, so please consult REEF Trips prior to booking your flights to ensure that your itinerary will fit the current COVID testing schedule. Please review the testing and entry requirements on this page. Once you are on the page, scroll down to the Palau section of the table.

Hotels:  Early arrival guests must provide a travel itinerary that shows they have stayed at "Pandemic Certified" facilities during their first four days upon their arrival. The Palau Aggressor II and Rock Islands Aggressor are both "Pandemic Certified." All hotels booked for guests through Aggressor Travel are “Pandemic Certified.” If you require a hotel before boarding the boat, we suggest contacting Aggressor Travel for booking guidance at

Transfers: There are no phones or taxis at the airport, so advance reservations must be made. Airport transfers are not included in the cost of the trip package. After you have made your flight and hotel arrangements, please notify REEF of your plans so that transfers can be arranged. Guests will be picked up from hotels between 4-5pm for boarding on June 26. The staff will assist with organizing transportation to either the airport or your hotel on July 6.

Passports, Documentation and Visas: Visitors must have a current passport, adequate funds to support themselves, and a return airline ticket to travel to Palau.

It is the participant's responsibility to ensure that they understand and comply with all local requirements (for entry and visit as a tourist) of the host destination, and for exit and entry requirements for their home country. Be prepared for your plans to change. Be sure your travel insurance covers COVID-related issues. No travel is risk-free during the COVID-19 pandemic. Countries may further restrict travel or bring in new rules at short notice, for example, due to a new COVID-19 variant. Please be aware that REEF is not a travel agent.
