Tucked beneath the towering emerald cliffs of Kauai’s North Shore, Tunnels Beach, also known as Makua Beach, offers one of Hawaii’s most breathtaking underwater experiences. This scenic beach is not just a favorite among photographers and sunset seekers—it’s also a top destination for snorkeling with Hawaiian green sea turtles.
Why Tunnels Beach is a Snorkeling Paradise
The beach gets its nickname from the unique underwater lava tubes and caverns (or “tunnels”) that form a complex reef system offshore. These natural formations create the perfect environment for marine life to thrive, attracting snorkelers of all skill levels eager to explore its aquatic wonders.
The outer reef protects the inner lagoon from strong currents, making the nearshore waters calm and clear in summer—ideal conditions for snorkeling. Just steps from the beach, you’ll encounter sprawling coral gardens, schools of tropical fish, and of course, the gentle honu, or Hawaiian sea turtle.
Turtle Encounters at Tunnels Beach
Makua Beach is known for its frequent turtle sightings. These majestic creatures often glide slowly through the water or rest peacefully on the ocean floor near coral outcrops. While spotting a turtle here isn’t guaranteed, your chances are high, especially during early morning hours when the beach is less crowded.
Important Reminder: It is illegal to touch, feed, or harass sea turtles in Hawaii. Keep at least 10 feet (3 meters) away, and always let the turtle approach you—not the other way around.
Tips for Snorkeling at Tunnels Beach
- Best Time to Visit: Summer months (May–September) bring the calmest waters. Winter can bring dangerous surf, so avoid snorkeling during high swell conditions.
- Gear Up: There are no rental shops on the beach. Bring your own gear or rent from nearby Hanalei before heading out.
- Enter Safely: Stick to sandy entry points between rocky outcrops. The reef is alive—avoid stepping on coral.
- Stay Visible: Wear bright gear or bring a snorkel buoy, as surf conditions can shift.
