Diving in Kosrae Activities

One of Kosrae's greatest attractions is the clear, clean ocean and its extraordinary living coral reefs that completely surround it. Offshore, the coral reefs slope steeply into the clear blue depths. Both vertical drop-offs and undulating profiles of cascading corals appear before you, as underwater visibility averages 100 to 200 feet. The reefs comprise hundreds of densely packed coral species, both hard and soft, attracting an abundance of marine life. A diver could easily observe 50 species of fish in a single dive. Turtles and rays inhabit the waters of this island paradise, and if you enjoy finding Nudibranchs and other macro subjects, you'll be delighted.

Kosrae's shape provides a sheltered side of the island (in case the trade winds blow a little hard). Our divemasters have a wealth of experience and will cater to your every need, no matter what your diving experience.

Imagine yourself diving and photographing a sheer vertical wall with hundreds of Pacific barracuda encircling you, feel your eyes widen in amazement at the huge and remarkably colorful coral reef systems, or watch the resident spinner dolphins as they jump and twirl for your entertainment.

A Typical Dive Day in Kosrae

7:00 am: Time for breakfast, our restaurant is open and waiting. Feel free to let us know if you think you might need a wake up call, or you can set the clock radio in your room.

8:15 am: Meet at the dive shop, get your gear together and ready to load into the trailer. Don't forget to bring your certification card if this is your first day with us. We will need you to read through and sign our standard NAUI waiver form.

8:30 am: Our mini bus will drive you to one of the 3 marinas where we keep our boats. Kosrae is roughly triangular in shape with a high volcanic mountain in the center, so this usually makes for at least one side of the island to be shadowed from any wind that might be around. With this choice of three marinas to start our diving from, we can choose the best side of the island to give you optimum diving conditions for that day.

At the marina we load all of the equipment onto the dive boat and have you assemble it before the boat leaves the marina. If you need assistance our staff will happily assist. We fit you on board with weights and tanks.

Once on our way and outside the harbor we can assess wind and swell to choose the best dive site for the start of the day. All dive sites are a mere 5 to 30 minute boat ride away, with over 60 mooring buoys to choose from. The dive briefing for the chosen dive site is given once we're tied onto the mooring buoy.

For maximum safety our dive guide will tow a surface float and the group will normally drift with the current. If the current changes direction, the guide will usually choose to change direction and go with the flow. Both guides let you dive your own profile and leave you to enjoy your dive as much as possible. However, if they see something interesting they are only too happy to point it out to you.

Between dives we take a one hour surface interval allowing time to snorkel if you wish. During this time you will be served fresh local fruit including some of the best bananas you'll ever taste, and some famous Kosraean tangerines. Depending on the season, we may also serve strawberry papaya, or local pineapples, both are a real treat. We also provide plenty of drinking water to ensure everyone is well hydrated.

After the second dive, we enjoy lunch on the boat before heading back into the harbor. Arrival back at the hotel is between 1.30 and 2.30 pm. If you wish to do three dives we get back about two-hours later.

Once back at the resort and after rinsing out the gear it is time to relax, go for a swim in the pool, or a snorkel out front on the reef, or simply read a book and relax till dinner time.
