Tunnels Beach, Kauai Travel Guide: Attractions, Things to Do And More

Last Updated on 24 Apr 2024 by Fiona Perisone


Tunnels Beach is one of Kauai's beautiful beaches with spectacular sunset and is perfect for snorkeling and scuba diving. A brilliant coral reef reaches nearly the shoreline during low tide. The reef and the island are riddled with caverns and tunnels, which are fun to explore and offer prime habitats for underwater wildlife. This beach is great for surfing and snorkeling! Below, we'll go over what you'll need to know to make the most of your trip to Tunnels Beach, Kauai!

Best Time To Visit Tunnels Beach

During the winter months, large waves buffet the north shore beach of Kauai. These high waves make the tunnels too dangerous to explore, as well as put the surfing out of the capabilities of beginning and intermediate surfers. During the summer months, you'll battle crowded beach fronts and long lines for tours and outings. It's better to visit Kauai Tunnels Beach in spring and fall.

Where Is Tunnels Beach (aka Makua Beach) Located?

Makua Beach is found on the north shore of Kauai, one of the Hawaiian islands. It's on the western point of a crescent-shaped bay. It gets its nickname of "Tunnels Beach" because of the many underwater formations created by lava tubes. When these lava tubes form, they create underwater caverns and tunnels, both through the island and the coral reef.

Best Things To Do In Tunnels Beach

While all of the Kauai beaches are interesting, the main attractions of Tunnels Beach are its snorkeling and surfing!


Because of the unique lava tubes and the formations they caused, the underwater world of Tunnels Beach is stunning and not to be found elsewhere! It's also unique because it has an inner and outer reef. The inner, half-moon-shaped reef reaches nearly the shoreline during low tide, and the tunnels through the reef have made it the perfect habitat for tropical fish and sea turtles! This makes for great snorkeling, especially for novice snorkelers that should stay near the shore and you wouldn't see much on other beaches. In fact, snorkeling in the outer reef area is no better than snorkeling closer to shore! And snorkeling in the outer reef is significantly more dangerous, with steep drop-offs and strong currents.

Scuba Diving

The incredible underwater sights you'll see while snorkeling is also accessible while scuba diving! There is a slight rip current flowing almost continually, but it's rather weak.


Tunnels Beach is a popular spot for all sorts of surfing. Surfing, windsurfing, and kite surfing are done all up and down this beach. While there are areas of the beach suitable for beginners and intermediate surfers, there is a surf break beyond the outer reef that is a perfect challenge for experienced surfers. In fact, some surfers call Makua Beach "Tunnel Beach" more because of this more difficult surf break than because of the reef tunnels!


For a readily-accessible trail, the 4-mile Hanakapiai Falls Trail in Haena State Park is a great option. However, the Kalalau Trail, in Na Pali Coast State Park, is the most famous trail in all of Hawaii. It's not only famous for its beauty - and it is beautiful, passing many waterfalls - but also for its difficulty. It is 22 miles round trip, with many elevations and terrain changes. The trail is narrow, muddy, and jagged. In portions, hiking takes a back seat to something more like rock climbing. A permit is needed to hike the Kalalau trail, and it's important to note that that permit also grants you access to Haena State Park.


There are many reasons why Tunnels Beach is ideal for general sightseeing, like beach walking, scoping out sunsets or photography. Tunnels Beach is a crescent-shaped bay, and palm trees and ironwood trees edge the golden sand beach. The combination of island mountains, lush jungles, and golden beaches make this a picture-perfect beach. The crescent shape means that this backdrop faces the ocean and frames it.

How To Get To Tunnels Beach, Kauai

Since Tunnels Beach is in a residential area, beach access points are somewhat limited to street parking. Take state highway 56 West out of Hanalei for 5 miles to get there. After passing mile marker 35 and making your way through the neighborhood, look for a "Tunnels" sign to the left on Waikanal Road. Then, look for mile marker 8. There will be two short dirt roads along this mile, at 0.4 and 0.6 miles past the marker, that will lead to Tunnels Beach. Since you're limited to street parking, you'll need to go early in order to find a legal spot. Many choose instead to park in Haena State Park and walk the half mile to Tunnels Beach.

Golden Tips

Lack Of Amenities

Tunnels Beach is in a residential neighborhood. There is a lack of amenities on the beach, such as restrooms, showers, or picnic tables. There also won't be a lifeguard on duty, except during the summer months. Your closest access to beach amenities and lifeguards is at Haena Beach Park, about a quarter mile away.

Bring Reef Safe Sunscreens

The Makua reefs are a vital part of Tunnels Beach. Many types of sunscreen are harmful, and sometimes deadly, to a reef's ecosystem. Before you visit Tunnels Beach, get a reef-safe sunscreen - and apply it frequently! The sun is intense!

Go Early

There are limited parking spots available, so parking can be challenging. Get there early in the morning, and you should be fine with parking. Otherwise, you can park at Haena Beach Park and walk over.
