Tunnels Beach Kauai, also called Makua Beach, is a reef-fringed beach on the North Shore in Haena, near the end of Kuhio Highway. The reef draws snorkelers on calm summer days. Winter surf can be dangerous. Parking nearby is limited and fills fast.
Where is Tunnels Beach Kauai?
Tunnels sits on the north coast of Kauai, in Haena. The Kauai County Ocean Safety Bureau calls it Makua Beach, also known as Tunnels. Wikipedia places Kee Beach to the west of Tunnels. Kee Beach is inside Haena State Park, which Hawaii State Parks says sits at the northwestern end of Kuhio Highway.
The name comes from the reef. Hawaii-guide.com, a travel guide, says “Tunnels” refers to lava tubes that run through the reef and into the ocean.
I plan trips around seasons and logistics before I plan around sights. On the North Shore, that order matters. Where you leave the car shapes the whole day.
Do you need a reservation for Tunnels Beach?
No official page answers this directly. Hawaii State Parks says visitors entering Haena State Park need a park entry reservation, a parking reservation or a valid Napali Coast camping permit. Those reservations open 30 days ahead. Hawaii residents with a Hawaii driver license or state ID are exempt. Neither the state parks page nor gohaena.com, the park’s reservation site, mentions Tunnels, Makua or Haena Beach Park.
The map points one way. Wikipedia says Limahuli Stream marks the park’s eastern edge, and that Haena Beach lies just east of the park. An unofficial blog, tunnelsbeach.org, says Tunnels is not part of the state park and is free to visit. It names no agency as its source, and its own disclaimer makes no promise of accuracy.
So Tunnels itself does not appear to need a state park reservation. That is a reading of the map, not an official ruling. Before you go, check the Haena State Park page from Hawaii State Parks, or email info@gohaena.com and ask.
Tunnels Beach parking
The public lot that guides point to is at Haena Beach Park. Hawaii-guide.com lists it as 0.4 miles from Tunnels. Kauai.com says parking there is limited and can fill up quickly during peak times. In 2019, The Garden Island put the county lot’s usual capacity at about 60 spaces. Snorkeling-report.com warns of many no-parking areas near the path to the beach, which it puts about 100 yards from the main road.
I check parking rules before I check the surf. Here, the rules are enforced. In February 2023, The Garden Island reported that illegal parking along state highways, such as the road to Haena State Park, carries a $235 fine. It said 1,348 parking citations were issued in the Hanalei area in 2022. Joel Guy of the Hanalei Initiative estimated that at least 85 percent of North Shore tickets were written around Haena Beach Park. Gohaena.com now warns that tickets near the park run $200 or more, and that cars can be towed.
- Arrive early, before the lot fills.
- Read every sign. A row of cars on the shoulder does not make it legal.
- Do not treat the Haena State Park lot as overflow. Non-residents need a reservation to enter.
- Hawaii-guide.com says not to assume a nearby beach park or residential street is legal parking.
- Have a second beach in mind. A different beach beats a $235 ticket.
Safe Beach Day lists restrooms, showers, picnic areas, a snack shack, gear rental and metered parking at Haena Beach Park. Read the posted signs when you arrive.
Haena Beach Park as your base
Haena Beach Park is a county beach park on low dunes behind Maniniholo Beach, per Safe Beach Day. It has facilities that Tunnels lacks. It also has its own danger. Safe Beach Day says no reef protects the beach itself. In winter and spring, waves can hit the sand with a pounding shorebreak, strong backwash and powerful rip currents.
The same page says the park has seen a number of drownings and many near-drownings, mostly among swimmers and bodysurfers in the shorebreak. Lifeguards are not always on duty. For a wider look at the island’s sand, see our guide to the best beaches on Kauai.
Tunnels Beach snorkeling and the reef
Snorkeling is the reason most people come. Snorkeling-report.com says the best area is the reef that runs parallel to the western part of the beach. Enter the water and it is on your left. From the access path, it says to walk a few dozen yards to the right to reach the best entry spots.
Depth changes fast. Over sand and coral the water runs about 3 to 7 feet, according to that report. Then you reach a reef drop-off where the depth increases sharply, to roughly 7 to 20 feet. Hawaii-guide.com says the reef comes within a few feet of dry land at low tide.
Hawaii-guide.com calls the inner reef shelf the calm-season snorkel zone. It also notes a slight rip current that is usually weak. Snorkeling-report.com is less relaxed. It says moderate currents can occur even when sea conditions are good.
Hawaii-guide.com lists tropical fish, eels, octopuses and crabs around the reef. Snorkeling-report.com adds one limit: the shallow lagoon around Haena Point is now closed to all water activities, snorkeling included. Obey posted signs. For other spots, see our guide to the best snorkeling on Kauai.
Stay off the coral. Our Hawaii packing list covers what to bring for beach and snorkel days.
Tunnels Beach winter surf and closures
Winter brings a different beach. Hawaii-guide.com says winter surf and currents can be dangerous. It describes two surf breaks, one at the mouth of the beach and one farther out. Snorkeling-report.com calls the spot impracticable to visit in winter, when big waves roll onto the North Shore.
Kauai.com says the seas are generally calmer in summer. In winter, it says, strong waves and currents can make conditions harder. Gohaena.com, the Haena State Park site, tells visitors to expect rough ocean and more rain from October through April. It also says streams in the area are high risk for sudden flash flooding.
If you are planning a cooler-season trip, our Hawaii in December guide covers what to do instead.
Park closures happen too. Hawaii State Parks posted that Haena State Park would reopen on Thursday, October 15, 2026. A notice dated October 24, 2026, on gohaena.com said the park and shuttle had reopened for day-use hiking to Hanakapiai. Overnight camping and hiking past the two-mile point on the Kalalau Trail stayed closed until further notice. Check both pages on the day you drive out.
Currents, sharks and lifeguards at Tunnels
Do not count on a guard at Tunnels. Hawaii-guide.com, Kauai.com and snorkeling-report.com all list no lifeguard there. The county does staff a Haena lifeguard tower. A June 2026 county notice said it closed for a time when flooding at Manoa Stream blocked the highway.
County lifeguards have closed the water at Tunnels before. In October 2023, Ocean Safety advised no swimming at Makua Beach after a shark of about 8 feet was seen in the channel. In October 2024, the county suspended ocean activities at Haena Beach Park and the Makua Beach area after a tiger shark of about 10 feet was spotted off Haena. No injuries were reported either time. Warning signs went up, and lifeguards reassessed the next day.
Pick a day when the surf is small, stay on the inner reef, and swim with a partner. For current conditions, the county says to talk to a lifeguard at any station or call the Ocean Safety Bureau at 808-241-4984.
Best time to visit Tunnels Beach
Summer is the best season. Kauai.com says the seas are generally calmer then, and hawaii-guide.com ties good snorkeling to calm summer seas. Time of day matters mostly for parking. Go early and check the surf report before you commit.
Anyone who has chased a parking spot at a popular beach knows the rule. Go before the crowd, and keep the plan loose. If the lot is full at Haena Beach Park, move on and come back another day.
