Why Okinawa is a Top Destination for Snorkeling

Okinawa’s pristine waters and rich marine biodiversity make it a top destination for snorkeling enthusiasts worldwide. The region boasts over 200 islands, each offering a unique snorkeling experience. Whether you prefer calm lagoons or adventurous open-water snorkeling, Okinawa has it all.

One of the main reasons Okinawa stands out as a snorkeling destination is its vibrant coral reefs. These reefs are home to a remarkable variety of coral species, including beautiful fan corals and brain corals. With the smaller size of the island, you can explore the best locations easily in even just one week in Okinawa!

In addition to the coral reefs, Okinawa is known for its clear, warm waters. With visibility often exceeding 30 meters, snorkelers can fully appreciate the underwater beauty. The temperature of the water remains comfortable year-round, making Okinawa an ideal destination for snorkeling at any time.

Best Time To Visit Okinawa for Snorkeling

While Okinawa offers fantastic snorkeling opportunities throughout the year, the best time to visit depends on your preferences and what you hope to see underwater. Generally, the period from April to October is considered the peak snorkeling season in Okinawa, with warm water temperatures and excellent visibility.

During this time, you can expect to encounter a wide range of marine life, including sea turtles, colorful fish, and vibrant coral formations. If you’re lucky, you might even spot manta rays gracefully gliding through the water.

However, if you prefer a quieter snorkeling experience with fewer crowds, the off-peak season from November to March is also a great time to visit. While the water may be slightly cooler, the calmer conditions, increased visibility, and reduced tourist activity create a tranquil atmosphere for the best snorkeling in Okinawa.

1. Blue Cave, Onna Village

Imagine swimming into an underwater cathedral bathed in an ethereal blue glow. Sunlight filters through an opening at the top of the cave, illuminating the vibrant coral formations that line the walls. Schools of colorful fish dart between corals, as sunlight filters through the aqua blue water.

Topographical Features: The Blue Cave is a shallow cave system accessible through a small opening at the water’s surface. Inside, the cave expands, offering spacious chambers and crevices to explore.

Wildlife: Expect to see an abundance of tropical fish, including butterflyfish, angelfish, and parrotfish. Sea turtles are also occasionally spotted grazing on the algae-covered rocks.

Dive Conditions: Entry and exit are through a small opening, which can be challenging in rough conditions. The cave itself is well-lit and calm, with good visibility. However, be mindful of changing tides and currents.

2. Gorilla Chop

No tour of Okinawa snorkeling would be complete without mentioning the iconic Gorilla Chop. This spot features a rock formation resembling a mighty gorilla performing a karate chop (we didn’t see it, but it’s a memorable name!)

The diverse marine life and sheltered bay make it a popular choice for families and beginners, but can get very crowded in peak season.

Topographical Features: Gorilla Chop boasts a gently sloping reef with sandy stretches and coral formations perfect for exploration. The sheltered bay offers calm conditions and excellent visibility.

Wildlife: Expect to see a variety of colorful fish, including clownfish, butterflyfish, and angelfish. Sea turtles are also commonly spotted in the area, making it a perfect spot for underwater photography. My partner even spotted an octopus!

Dive Conditions: The waters around Gorilla Chop are typically calm and sheltered, making it ideal for beginner and intermediate snorkelers. However, be mindful of occasional boat traffic, especially during peak season.

3. Kunigami Sea - Western Coast of Northern Okinawa

Find anywhere you can park along the western coast of the northern region of the island, and you’ll explore the best snorkeling in Okinawa right from shore. There is no set location or ideal snorkeling spot as it is all beautiful. I recommend driving up the coast, pulling over where there is a good spot to park, and hitting the water if it looks calm!

Topographical Features: Dive through trenches among vibrant coral life, only a short swim from the beach. Swim over vast arrays of flat corals, among tropical fishes and fellow freedivers!

Wildlife: Expect to see a wide variety of marine life, including tropical fish, sea turtles, manta rays, and more! As a reminder, do not touch any aquatic life.

Dive Conditions: Visibility is high, boat traffic is low, and there aren’t nearly as many tourists as the other 2 mainland locations. A current can be present, so it’s important to talk with a local or do some research before entering the water.

Locations You Can't Swim

While researching, I found a lot of misleading information on snorkeling locations. I feel it’s important to set some things straight! You cannot swim at Cape Manzamo (Mermaid’s Grotto). 

Online, this was listed as a ‘beginner-friendly’ spot, but when we arrived with our floaties in hand.. we pulled up on some aggressive signs that it was very dangerous. If you’re not sure about a location, ask a local, or a dive master, and use your best judgment!

Snorkeling Equipment & Safety Tips

Before embarking on your snorkeling adventure in Okinawa, it’s essential to have the right equipment and follow safety guidelines to ensure a safe and enjoyable experience.

  1. Snorkel Gear: Invest in a high-quality mask, snorkel, and fins to maximize your comfort and snorkeling efficiency. A well-fitting mask with a silicone skirt and a dry-top snorkel that prevents water from entering are crucial for a hassle-free snorkeling experience. These are available for rent or borrow from most accommodation hosts!
  2. Sun Protection: Apply a waterproof sunscreen with a high SPF to protect your skin from the sun’s harmful rays. Wearing a rash guard or a wetsuit can also provide additional sun protection.
  3. Swim with a Buddy: Always snorkel and dive with a buddy, preferably someone who is experienced and confident. Having a buddy ensures safety and allows for a more enjoyable snorkeling experience.
  4. Be Mindful of Currents: Before entering the water, familiarize yourself with the local currents and tides. Snorkel in areas with calm waters and avoid strong currents to prevent accidents and ensure your safety.
  5. Respect Marine Life: While snorkeling, refrain from touching or harassing marine life. Maintain a safe distance to avoid causing stress or harm to the underwater creatures. Remember, you are a guest in their natural habitat.

Snorkeling Tours & Guides

As a certified free diver, SCUBA diver, and frequent snorkeler, I never did an official tour! With over a month to explore the island and a rental car, we went for self-led exploring.

However, if you’re only visiting for a short period, are new to the water, or just want to see the best places without thinking about anything else, a tour is a great option!
