8 Of Kauai’s Best Snorkeling Spots

Kauai is a fantastic snorkeling destination, and a trove both above and below the surface. While its lush mountains and dramatic cliffs often steal the spotlight, the underwater world surrounding this island is equally breathtaking.
With clear waters, thriving coral reefs, and a vibrant variety of marine life, snorkeling in Kauai is one of the best ways to explore its natural beauty.
In this guide, we’ll dive into eight of Kauai’s best snorkeling locations, complete with tips on accessing them, what you’ll see, and why each one stands out.
-
Tunnels Beach (Makua Beach)
Location: North Shore, near Haena
Best for: Intermediate to advanced snorkelers
Highlights: Underwater lava tubes, colorful reef fish, and turtles
Tunnels Beach is widely considered one of the top snorkeling destinations on Kauai, thanks to its striking underwater topography and expansive reef system.
The inner reef is calmer and great for spotting butterflyfish, parrotfish, and sea turtles. More experienced snorkelers can venture toward the outer reef to explore larger coral heads and dramatic underwater arches.
Pro Tip: Visibility is best in summer months. During winter, swells can be strong, and snorkeling conditions are unsafe.
-
Ke’e Beach
Location: End of Kuhio Highway (Hwy 560), North Shore
Best for: Beginners and families
Highlights: Calm lagoon, easy access, scenic backdrop of the Na Pali Coast
Ke’e Beach offers a picturesque introduction to snorkeling, with calm, protected waters surrounded by lush jungle cliffs. The lagoon is home to angelfish, wrasse, and even the occasional octopus. It’s an ideal location for first-timers or those looking for a relaxed snorkel session.
Pro Tip: Ke’e Beach requires a reservation through the Haena State Park website, especially during peak season.
-
Anini Beach
Location: North Shore, near Princeville
Best for: All skill levels
Highlights: One of Hawaii’s longest fringing reefs, with very calm conditions
Anini Beach is a hidden gem when it comes to snorkeling on Kauai. Its shallow waters and protective reef make it ideal for beginners and children. The area teems with tangs, goatfish, and occasionally, rays. It’s also less crowded than other North Shore spots.
Pro Tip: Bring reef-safe sunscreen and snorkeling shoes, as the entry can be rocky.
-
Lawai Beach
Location: South Shore, near the Beach House Restaurant
Best for: Intermediate snorkelers
Highlights: Tropical fish density, easy access, and nearby facilities
Lawai Beach may be small, but it is densely populated with reef fish and vibrant corals. Just steps from the road, it’s a favorite among locals and visitors alike.
Look for Moorish idols, Christmas wrasse, and the state fish of Hawaii, the humuhumunukunukuāpua’a.
Pro Tip: Arrive early to grab parking and avoid crowds. The beach is narrow and can get busy.
-
Poipu Beach Park
Location: South Shore, Poipu
Best for: Families and beginners
Highlights: Monk seals, lifeguards, sheltered cove
Poipu Beach is consistently rated one of America’s best beaches, and snorkeling plays a big part. The sheltered cove is perfect for kids and first-time snorkelers. You may even see Hawaiian monk seals sunning onshore, sea turtles, and schools of vibrant reef fish. Poipu Beach is known as one of the best beaches for snorkeling with turtles!
Pro Tip: Stay in the designated swimming area and check conditions with the lifeguard before entering.
-
Koloa Landing
Location: South Shore, off Kapili Road
Best for: Advanced snorkelers and shore divers
Highlights: Deepwater access, large coral formations, sea turtles
Often referred to as one of the best shore dives on Kauai, Koloa Landing is also a fantastic spot for experienced snorkelers.
The entry is rocky, and currents can be strong, but the payoff includes encounters with moray eels, turtles, and sometimes even spotted eagle rays.
Pro Tip: Go with a snorkel buddy and wear fins for better mobility in deeper water.
-
Lydgate Beach Park
Location: East Side, near Wailua
Best for: Young children, new snorkelers

Location: South of the Na Pali Coast, near Waimea
Best for: Adventurous snorkelers and boat tour guests
