My friend Maya and I once drove past Tunnels Beach three times. We were looking for a grand entrance, a ticket booth, maybe a guy in a Hawaiian shirt waving a flag. Instead, we ended up at Haena Beach Park, confused and slightly sunburned.
A local finally took pity on us and said, “You already passed it, brah.” That’s the thing about Tunnels—it doesn’t announce itself.
So if you’re planning to snorkel those famous lava tubes, you need a little local knowledge. Not the secret kind that requires a blood oath. Just the practical kind that keeps you from driving in circles.
Must Read
Here’s how to actually get there.
First, Know What You’re Looking For
Tunnels Beach is also called Makua Beach. It sits on Kauai’s North Shore, past Hanalei and before Haena. The name “Tunnels” comes from the underwater lava tubes that create good snorkeling when the ocean is calm.
There is no big parking lot. No visitor center. No neon sign.
Just a narrow beach access path and a stretch of sand that will make your phone camera weep with joy.
Driving Directions from Hanalei
From Hanalei, take Kuhio Highway (Route 560) west. You’ll cross the one-lane Hanalei Bridge, which is its own little adventure. Keep driving for about five miles.
Watch for mile marker 8. Tunnels is right around there. If you’re heading toward Haena, the small parking area is on your right, on the mauka side (that’s mountain side, for you non-locals).
If you see a bunch of cars parked along the road, you’re close. If you see a sign for Haena Beach Park, you’ve gone too far. Turn around, but do it safely.

Parking Reality Check
The parking area is tiny, dirt, and usually full by 9 a.m. Maybe earlier. Roadside parking looks tempting, but many spots are illegal.
You might see other cars doing it, but that doesn’t mean you should. The small lot fills up fast, so carpool if you can. And no, idling in the middle of the road is not a strategy.
In recent years, Haena State Park has required advance reservations for parking and entry. That applies to Haena Beach Park and Ke’e Beach. Tunnels itself sits outside that reservation zone, but the nearby parking is still a headache.
If you have a Haena reservation, you can park at Haena Beach Park and walk east to Tunnels. If you don’t, stick to the small legal pull-offs near mile marker 8. Or come back another day. Seriously.
The Walk to the Sand
Once you park, look for a narrow path between the trees. It’s not marked with flashing lights. You’ll walk a short distance, and then the beach opens up in front of you.
The sand is soft, the water is blue, and the ironwood trees frame the whole scene. The “tunnels” are underwater, so don’t expect to walk through a cave. They’re for fish and snorkelers, not dry-land explorers.
When to Go
Summer is the best time for snorkeling. The water is usually calmer, and visibility can be amazing. Winter brings big north swells, strong currents, and dangerous shorebreak.
Even in summer, check the surf report before you go. Tunnels is not a swimming pool. If the water looks rough, stay on the sand and enjoy the view.

There are no lifeguards at Tunnels. There are no bathrooms. Plan accordingly.
Go early. Like, sunrise early. Parking is a nightmare after 10 a.m., and the beach gets crowded. You didn’t drive all that way to fight for a spot.
Local Etiquette, Quick Version
Don’t park on private property. Don’t block driveways. Don’t leave valuables in your car.
Don’t take sand or rocks. It’s illegal, and it’s disrespectful. Also, this is a residential neighborhood, not a resort.
Keep your voice down and your trash with you. It’s a simple rule that keeps paradise from turning into a parking lot.
The Bottom Line
Getting to Tunnels Beach isn’t hard, but it isn’t obvious either. You need the mile marker, a parking plan, and a backup plan. If you do it right, you’ll find one of the most beautiful beaches in Hawaii.
If you do it wrong, you’ll spend your morning circling Haena and muttering to yourself. Trust me, I’ve been that person. Learn from my sunscreen-stained mistakes.
And if you miss it, don’t worry. The North Shore has plenty of other magic. Just maybe bring a map next time.
