Golden sandy beaches and deep blue, crystal clear Pacific Ocean waters! Amazing tropical fish to gawk at while snorkeling!

I could be talking about any of a dozen beaches in Kauai.

But Tunnels Beach (aka Makua Beach) is unique among the best Kauai beaches.

That you’ll have golden beaches and clear blue waters, and see amazing tropical fish while snorkeling in Tunnels Beach is a given. After all you are in Hawaii!

However, the underwater seascape of Tunnels Beach is extraordinary. When ancient boiling lava met the deep blue Pacific Ocean waters, they formed all kinds of underwater structures: lava tubes, underwater caves, tunnels, arches and more!

Tunnels Beach Directions

Tunnels Beach, part of the Maniniholo Bay on the North Shore of Kauai, is about 5 miles west from Hanalei along the Kuhio Highway (Hwy 560).

You will see signs for the Tunnels Beach Access Road after mile marker 8, and there are two small roads (about .4 and .6 miles past the marker) that lead to Tunnels Beach.

Drive slowly, you are in a residential neighborhood.

You can use tunnels beach hawaii 96746 for Google maps or GPS.

Tunnels Beach Parking

Parking for Tunnels Beach is a sorry situation. At the Tunnels Beach access point, you are in a residential neighborhood, with a few parking spots that get filled quickly. If you reach here by 9:00 am, you will likely find a spot.

I’ve seen cars double-parked along the fences of homes, obviously not friendly to the locals.

The best option for Tunnels Beach parking is to actually park at the adjacent Haena Beach Park (not to be confused with Haena State Park), a local county park with ample parking and other facilities.

You can walk down along the beach to Tunnels Beach, one continuous stretch of beach, about a 10-30 minute walk depending on where you want to end up.

If you have multiple people and a lot of equipment, you can drop off your equipment and everyone at the Tunnels Beach Access Road parking, and then have one person drive and park at Haena Beach Park.

Best Things to Do at Tunnels Beach, Hawaii

Makua Beach, fondly nicknamed Tunnels Beach by visiting divers and surfers after the lava tubes and tunnels, is one of the best Kauai beaches, providing family friendly spots as well as exciting opportunities for the adventurous tourist.

As with the rest of the North Shore Kauai beaches, you must align your beach activities with the seasons and weather.

During winter, North Shore Kauai beaches are more popular for surfing and related activities, and with frequent high surf and stormy weather conditions, swimming and snorkeling are usually prohibited.

During summer, the waters around Tunnels Beach are calm and clear, favoring activities like snorkeling.

1. Tunnels Beach Snorkeling

One of the best Kauai snorkeling beaches during summer, Tunnels Beach offers ample coral reefs all along the shore, and, best of all, you can explore these coral reefs, even further off the shore, in relatively shallow waters, often less than 5 feet deep.

There are actually two reefs, an inner reef right next to the shore and an outer reef further away.

The inner reef is perfect for beginning snorkelers and kids, and you are mostly in shallow waters. I was pleasantly surprised at the abundance of tropical fish so close to the shore.

We saw schools of the ubiquitous yellow and convict tangs, and most of the common but beautiful coral reef fish like butterflyfish, Moorish idol, goatfish, wrasse, and triggerfish (including humuhumunukunukuapua’a, the state fish of Hawaii).

Refer to our Hawaiian fish snorkeling guide to identify common and rare fish you can expect to see.

More experienced snorkelers can head towards the outer reefs where the diversity of tropical fish is better, and you can see larger fish that tend to congregate in the holes.

Be careful, since there are often strong currents further from the shore, and near the outer reef.

Tunnels Beach coral reefs are extensive and you can easily find a portion of the beach that matches your snorkeling capabilities, with some parts gentle, others more rough.

We saw plenty of Hawaiian green sea turtles (some hiding in the lava caves), and even a pod of spinner dolphins that entered the reefs and swam around with us for some time!

2. Tunnels Beach Swimming

During summer, the Pacific Ocean waters off Tunnels Beach are calm and conducive to swimming.

The adjacent Haena Beach Park is one of the best Kauai swimming beaches, and is more family-friendly for swimming, especially if you have smaller kids, with lifeguards and facilities like showers and restrooms.

However, Haena Beach Park tends to get crowded, and I often prefer to head to Tunnels Beach for a more relaxing swim.

Again, don’t venture too far from the beach, as strong currents and rip tides are ever present along Kauai beaches.

3. Laze or Sunbathe on the Golden Tunnels Beach

With about two miles of wide, golden sandy beaches and crystal clear, turquoise ocean waters, Tunnels Beach is a beautiful refuge for a quiet, relaxing time sunbathing or reading a book.

With shady palm trees and ironwood trees lining the coast, all you need to do is stroll around to find the perfect spot!

The setting is perfect: on one side lush, forested mountains sweeping towards the Mount Makana peak on the western end, and on the other, the golden sands and the beautiful, deep blue Pacific Ocean!

No wonder Tunnels Beach is one of the most heavily photographed Kauai beaches!

The Hollywood movie South Pacific was filmed here, and the pyramid-shaped Mount Makana Peak was called Bali Hai in the movie.

4. Stay Back for Spectacular Sunsets from Tunnels Beach

Strolling on Tunnels Beach at sunset is one of the most romantic things to do!

The sunset colors are spectacular, and watching the sun slowly sink below the ocean waters next to the pretty pyramid-shaped Bali Hai is a beautiful experience!

Tunnels Beach is one of the best sunset locations on Kauai, and we usually make it a point to stay back whenever we visit this beach.

5. Admire Turtles and Monk Seals on Tunnels Beach

Tunnels Beach is one of the few remaining pristine beaches on Kauai, unspoiled by development.

Given the residential location, and the difficulty finding parking, Tunnels Beach tends to be relatively uncrowded.

Which is great for the occasional Hawaiian green sea turtle or endangered monk seal that wants to take a peaceful nap on the beach!

On almost every visit to Tunnels Beach, we had the good fortune of seeing a few green sea turtles, and occasionally, solitary monk seals!

Please give them a wide berth, and admire them from far!

6. Surf Tunnels Beach

With winter comes windy weather, rainstorms, and, of course, towering waves!

Tunnels Beach is a surfer’s paradise! I’ve seen avid, dedicated surfers lug their boards over from the Haena Beach Park for this slice of paradise!

Renowned for its multi-location shore breaks, Tunnels Beach offers opportunity for different skill levels of surfing.

Expert surfers prefer the reef break far offshore, where the waves form large, towering tunnels, a delight for surfers!

Mid-level and beginning surfers stay closer to the beach, where the shore breaks are not as wild.

Apart from surfing, I’ve seen wind surfing and kite surfing here as well, and an occasional bodyboarder!

A helicopter tour is undeniably a fantastic way to admire the breathtaking landscapes of Kauai, from the Waimea Canyon to the Napali Coast and Jurassic Falls. Check price and availability now! 🚁 🚁

7. Scuba Dive or Sea Scooter Snorkel at Tunnels Beach

Adventure tourist seeking something more exciting than snorkeling? What about scuba diving and free diving?

With 25-70 foot dives, Tunnels Beach offers a beginner-friendly environment for scuba diving, and a maze of lava tubes, tunnels, caves and more to explore!

Multiple local vendors like Fathom Five offer guided shore diving tours, scuba diving lessons and certification, and refresher courses for the scuba-certified.

An alternative to scuba diving is snorkeling with a sea scooter, which gives you a wider range than just snorkeling.

Teenage kids in our group rented sea scooters from Princeville – Snorkeling Shore Excursion, and they had a great time exploring the coral reefs and the underwater labyrinth at Tunnels Beach!

>> Check pricing and availability on the Princeville – Snorkeling Shore Excursion now!

8. Kayak or Paddleboard or Canoe at Tunnels Beach

In late spring and summer, with the calm ocean waters and shallow depths ranging for quite some distance off the shore, Tunnels Beach is an excellent location for kayaking, standup paddleboarding and canoeing.

You can rent equipment from nearby Hanalei or Princeville, or choose to bring your own.

Last vacation, we were able to do a full-day family outing at Tunnels Beach, and the teenage kids in our group had a great time with sea scooter snorkeling, while some of the adults enjoyed a leisurely afternoon canoeing and kayaking.

Note, we parked at the Tunnels Beach Access Road parking to offload all the equipment and the kids, and a couple of us drove down to park for the day at Haena Beach Park.

Other Activities at Tunnels Beach

Fishing is a popular activity at Tunnels Beach, with the reefs providing ample food for tropical fish. We spotted some locals launching a fishing boat, and some kids trying their hand with spear fishing.

Snorkeling and Water Activities Gear Checklist

Though you can rent snorkeling gear or use the ones that come with tours, we invested in our own gear, mainly due to Covid-19 (why take the risk?).

• Snorkeling Gear Set: We love our Cressi Light Weight Premium Travel Snorkel Set for All Family, compact and easy to pack, great fitting, and very clear underwater. The Zenoplige Mask Fins Snorkel Set is a great budget option.
  
• Sunscreen: Hawaii’s sun can be harsh. Avoid sunburn with sunscreen compliant with Hawaii’s 104 Reef Act. The Sun Bum Original SPF 50 Sunscreen Spray, moisturizing with Vitamin E, is our go-to when we travel to Hawaii. Apply liberally and regularly!
  
• Underwater Camera: Want to capture Hawaii’s incredible underwater seascape and marine life? Your best budget option is the Fujifilm QuickSnap Waterproof Disposable Camera, reasonably cheap with good underwater photos! If you want high-end photos and video, you must invest in the premium GoPro HERO12 – Waterproof Action Camera, (waterproof to 33 feet)!
  
• Inflatable Life Jackets: If you’re planning paddle boarding, canoeing, kayaking and other water sports, and prefer your own life jacket, consider one of these two US Coast Guard approved options: the Onyx M-16 Series Belt Back Manual Inflatable Life Jacket or the Onyx A/M-24 Automatic/Manual Inflatable Life Jacket.
  
• Water Shoes: Some of Hawaii’s beaches have sharp lava rocks or coral reefs, good water shoes will protect your feet (but please do not walk on the reef!). We use the Merrell Hydro Moc rubber shoes (men’s, women’s), great for slippery rocks. If you prefer sandals, we recommend the Keen Newport H2 Closed Toe Water Sandals (men’s, women’s).
  
• Waterproof Waist Pack: Keep your rental car keys, cards, and phone dry and safe while you swim or snorkel with a dry bag. We love this 2-pack AiRun Tech Pouch with waist strap. The transparent one is touch-screen friendly!

Tips for Your Visit to Tunnels Beach, Hawaii

Tunnels Beach does not have any facilities, so make sure you bring all the food, snacks, drinks and gear you will need. Haena Beach Park has restrooms and showers, and is roughly 1/2 a mile walk.

Come early if you want parking close by. Weekends are usually busy, plan a weekday if you have flexibility.

Select a snorkeling spot based on your skill level, and beginners and kids have lot of options in shallow waters close to shore.

As with any each beach in Kauai, safety should be your primary concern, especially if you are with smaller kids. Haena Beach Park has lifeguards, and may be a better option with smaller kids.

Check weather forecasts and high surf conditions before entering the water.

Tunnels Beach ocean waters are rough in winter, and will usually be closed for swimming and snorkeling. Please heed all the posted signs.

Ocean Safety Tips

Hawaii’s beaches are beautiful, but ocean activities can be dangerous. Ocean conditions are dynamic and can change without warning.

Here are some tips to enjoy the ocean and beaches safely:

• ALWAYS heed posted warning signs.
• Check conditions just before you arrive at your chosen beach, and watch conditions at the beach for a bit before you decide to enter the water.
• Swim at a lifeguarded beach and ask the lifeguard for advice before you enter the water.
• Never turn your back on the ocean, whether you are standing at the shore or on a cliff above. If you see wet rocks or sand, it means the water has been here recently.
• Know your limitations, especially if you are not an experienced swimmer. If in doubt, do not go out.
• If you choose to enter the water, go with a partner or in a group.
• Know that alcohol can impair judgment and motor skills in the water.
• Keep children close and always keep your eyes on what they are doing in the water.
• Watch for sharp coral or rocks or sea urchins.
• Check advisories regarding water quality at various beaches here.
