Marine Life Highlights

Poʻipū Beach Park is a popular beach with a shallow, protected swimming area, making it an excellent place to snorkel. At Poʻipū Beach, you’ll find plenty of marine life: turtles, a number of fish, and the occasional monk seal. You don’t need to snorkel far from shore to see a wide array of sealife—the reef is a quick swim from shore.

Best Time to Visit

Poʻipū can get crowded, especially on weekends, so it’s best to snorkel in the morning before the rush. There is also a lot of free parking on offer at the Beach Park itself, which becomes very busy during summer. Getting there early or later in the afternoon is a must to be in with a chance of finding a space. Alternatively, parking along Halelilo Road close to the park is still a great place to secure a spot only a few minutes walk away.

Safety Tips

Poʻipū Beach Park is a great beginner snorkeling area thanks to its typically calm waters and lifeguards. First-timers and children can stick to the rocks that line the shore, graduating to the small reefs that sit just offshore. Always be mindful of the ocean conditions and follow the lifeguards’ advice to ensure a safe and enjoyable snorkeling experience.

Unique Features

Tunnels Beach, also known as Makua Beach, is a snorkeler’s paradise with its golden sand and stunning natural backdrop of mighty mountains and emerald-green trees. The beach gets its name from the labyrinth of underwater lava tubes, canyons, and pathways that create a wonderful habitat for sea creatures. Underwater lava tubes and large rocks make this location particularly unique and exciting for exploration.

Snorkeling Conditions

The best time to snorkel at Tunnels Beach is during the summer when the water is calm and clear, resembling glass. It is important to avoid snorkeling here in the winter due to rough water conditions. Advanced snorkelers can venture farther offshore to the barrier reefs and enjoy diving down for a closer look at the large coral heads and volcanic formations. Beginners can stay close to shore and still spot a variety of tropical fish.

Nearby Amenities

While Tunnels Beach is spectacular and picturesque, it is important to note that there are no facilities located here. Visitors should come prepared with their own supplies. The beach is located near the YMCA camp between Hanalei and Haena on Kauai’s north shore. For those planning to spend the day, it’s a good idea to bring along food, water, and any other necessities to ensure a comfortable visit.

Tunnels Beach offers an unforgettable snorkeling experience with its unique underwater features and stunning natural scenery. Whether you are a beginner or an advanced snorkeler, this beach has something to offer for everyone.

Keʻe Beach

Location and Access

Keʻe Beach is located at the very end of the road on Kauai’s north shore past Haena Beach Park. A reservation to visit Haena State Park and Ke’e beach is required and must be booked well in advance as it sells out quickly. The reef offers good swimming and snorkeling during summer months with calm seas, but it is very important to stay inside the reef and be aware of strong currents which tend to pull you around the corner towards the Na Pali Coast.

Seasonal Variations

Snorkeling here in the winter can be dangerous, so keep this place on the top of your list for summer vacations only. Many times in summer, the water is as calm as a swimming pool, allowing you to enjoy both the above and below-water scenery.

What to Expect Underwater

The reef, which sits just offshore, is home to a myriad of tropical fish and green sea turtles. Snorkelers can see a wide variety of fish and sea turtles. The underwater scenery is as breathtaking as the views of the cliffs above.

Keʻe Beach offers great scenery above and below water. Take in the views of the cliffs, then enter the water to explore the vibrant marine life.

Anini Beach

Anini Beach is a lovely strip of sand that offers very good snorkeling on Kauai. There are convenient amenities to make your time at the beach that much more relaxing. Bring lunch, walk beneath the huge shady trees, or watch the small boats come and go at the boat ramp. This beach is kid-friendly, especially in the area to the left, away from the boats. Unlike most north shore beaches, the water here is usually calm all year long.

Lydgate Beach Park

Lydgate Beach Park is a fantastic family beach destination on the island, offering a number of convenient amenities. The beach has multiple facilities on site, including outdoor showers, picnic tables, and restrooms. A section of the beach is lifeguarded, but we advise being cautious at all times no matter where you’re swimming and regardless of your experience when in the water.

Nualolo Kai

Historical Significance

Snorkeling Experience

The reef at Nualolo Kai is one of the best snorkeling locations to visit on Kauai. You can expect to see lots of fish and very healthy coral.

How to Get There
