Tunnels Beach, locally known as Makua Beach, is one of Kauai’s most beloved destinations. Renowned for its stunning beauty, vibrant underwater life, and picturesque mountain backdrop, this beach is a must-visit for anyone traveling to Hawaii.
Why Visit Tunnels Beach?
Tunnels Beach is often celebrated as one of the best snorkeling spots in Hawaii. Its unique reef structure creates an underwater labyrinth of tunnels and caverns, giving the beach its name. Whether you’re a seasoned snorkeler or a beginner, Tunnels Beach offers a fantastic opportunity to encounter an array of marine life, including colorful fish, sea turtles, and occasional sightings of monk seals.
Beyond snorkeling, the beach boasts a golden sand shoreline framed by lush vegetation and dramatic views of the Makana Mountain, often referred to as Bali Hai. This blend of ocean and mountain scenery makes Tunnels Beach a popular spot for photographers and nature enthusiasts alike.
Tunnels Beach Snorkeling
For those seeking a snorkeling adventure, Tunnels Beach is second to none. The reef system is divided into inner and outer reefs. The inner reef is ideal for beginners and families, offering calm, shallow waters teeming with marine life. The outer reef, more suitable for experienced snorkelers and divers, features deeper waters and more complex coral formations.

When snorkeling at Tunnels Beach:
- Bring your own gear: There are no rental facilities on the beach.
- Go early in the morning: The waters are clearest in the early hours, providing better visibility for spotting marine life.
- Check weather conditions: Strong currents can occur, so ensure conditions are safe before entering the water.
Tunnels Beach Parking
One of the challenges of visiting Tunnels Beach is parking. The area has limited parking spaces, and spots fill up quickly, especially during peak hours. Visitors are encouraged to arrive early to secure a spot. There are two main parking areas:
- Near Haena Beach Park (a short walk from Tunnels Beach).
- Along Kuhio Highway, though spaces here are very limited.
Tip: If you can’t find parking for Tunnels Beach, consider parking at Haena Beach Park and walking the rest of the way. It’s a scenic and manageable route.
Tunnels Beach Access
Accessing Tunnels Beach requires a short walk from the designated parking areas. The trail leading to the beach is well-marked and shaded by tropical foliage. While the walk is relatively easy, visitors should wear comfortable footwear, especially if carrying snorkeling equipment or other beach essentials.
Facilities and Amenities
Tunnels Beach is a natural and relatively undeveloped site, which adds to its charm but also means there are limited facilities. Here’s what to know before you go:
- Restrooms: Available at nearby Haena Beach Park.
- Lifeguards: Tunnels Beach does not have lifeguards, so swimmers should exercise caution.
- Food and Water: Bring your own snacks and water, as there are no vendors on-site.
Best Times to Visit
The best months to visit Tunnels Beach are during the summer (May to September), when the ocean is typically calmer, making it ideal for snorkeling. Winter months (October to April) often bring larger swells, attracting surfers but making swimming and snorkeling more challenging.
