Under the Arches: Makua Beach (Tunnels Beach) and Kauai’s North Shore from Reef to Sky
A reef-lined bay framed by cliffs — snorkel the gardens, fly the Na Pali, and photograph the light that makes Kauai iconic.
You arrive with salt on your skin and a long, lazy line of palm trees keeping watch. The road to Makua Beach (Tunnels Beach) shutters abruptly into a narrow pullout and a low, volcanic bluff; below it the sand opens like a palm to the Pacific. At first glance it’s a classic Hawaiian bay—white sand, turquoise shallows, and a coral rim—but the beach’s personality announces itself through sound: the surf that sings in summer and roars in winter, and the deeper, hollow notes that give the place its nickname. The tunnels—the jagged lava arches and underwater caverns beyond the reef—are the reason divers and snorkelers keep coming, and they’re visible as darker patches if you climb the bluff and look out across the horseshoe of reef.
Trail Wisdom
Arrive Early
Parking is limited; be there before 8 a.m. to secure a spot and enjoy calmer water for snorkeling.
Use Reef-Safe Sunscreen
Apply a mineral-based, reef-safe sunscreen before arriving to protect coral and avoid skin irritation.
Check Conditions First
Ask a local shop or check surf reports—summer is calm for snorkeling, winter can produce dangerous shorebreaks.
Book A Helicopter or Photo Slot Ahead
Doors-off flights and private photo sessions have limited capacity—reserve in advance for prime daylight windows.
Local Knowledge
Hidden Gems

Conservation Note
The reef is sensitive to pollution and warming; visitors are encouraged to use reef-safe sunscreen, avoid stepping on coral, and follow local marine-protection guidelines.
The area sits within traditional Hawaiian land divisions and was historically fished and tended by local families; the modern name 'Tunnels' refers to underwater lava-formed caverns used by divers.
Seasonal Guide
spring
Best for: Moderate snorkeling, Less crowded beaches, Wildflower viewing inland
Challenges: Variable surf, Occasional runoff after rains
Spring brings warming waters and fewer crowds than summer; aim for clear days after a dry spell to get the best reef visibility.
summer
Best for: Calm snorkeling, Clear visibility, Aerial photography
Challenges: Higher visitor numbers, Strong midday sun
Summer is the ideal season for snorkeling the reef and booking doors-off helicopter tours—plan for early arrivals to avoid crowds and peak sun.
fall
Best for: Transitional surf for bodyboarding, Photography at golden hour, Quieter shoreline visits
Challenges: Intermittent swell increases, Occasional wind
Fall can deliver good surf without the extreme winter storms; visibility can vary but sunsets become spectacular for photos.
winter
Best for: Big-wave viewing from shore, Watching surfers, Dramatic aerial views
Challenges: Dangerous shorebreaks, Strong rip currents
Winter transforms the beach into a powerful surf arena—great for watching from a safe distance but not for casual snorkeling or swimming.

Common Questions
Is Makua Beach safe for snorkeling?
In summer, yes—the reef creates sheltered pockets with good visibility; always check local conditions, avoid reef walking, and don’t snorkel alone.
Are there lifeguards?
Lifeguard presence is inconsistent; treat the beach as unguarded and be conservative with water entry, especially in winter.
Can I see turtles here?
Yes—green sea turtles (honu) commonly graze the reef; observe from distance and never touch or feed marine life.
How do I book the doors-off helicopter flight?
Reserve with a licensed operator in advance; flights typically depart from Lihue or nearby helipads, have strict weight and seating limits, and include a safety briefing.
Is parking available?
There’s a small public turnout; it fills early. If full, plan to park farther back and walk or combine the trip with a visit to Hanalei.
Do I need a permit to shoot photos?
For casual photos, no permit is required; commercial shoots and drone use may require permits—confirm with Hawaii County and the state parks office.
What to Pack
Snorkel set for reef exploration, reef-safe sunscreen to protect coral, water shoes for rocky entries, a lightweight dry bag to keep valuables safe.
Did You Know
