Why Tunnels Beach Is a Popular Snorkeling Spot
Tunnels Beach (Makua Beach) on Kauai’s north shore is widely considered one of the island’s best snorkeling spots — especially in the summer. The beach offers a unique reef system and a chance to see tropical fish, turtles, and interesting underwater formations.
For families with older kids or teens who are confident swimmers, Tunnels Beach can be a rewarding and adventurous snorkeling destination. However, this is not a beginner-friendly location like Poipu Beach, and parents should be aware of potential safety and access challenges.

When to Visit: Summer Only for Safe Snorkeling
Ocean conditions at Tunnels are seasonal, and the beach is not safe for snorkeling in winter months due to large north shore swells and strong rip currents.
Best time for family snorkeling:
- May through early September typically brings calmer waters.
- Even in summer, check surf conditions daily — especially if snorkeling with children.
During the winter (roughly November through March), families should avoid this beach for water activities and instead head to more protected locations like Poipu Beach Park or Lydgate Beach Park on the east side.
Getting There: Parking and Access Can Be Challenging
One of the biggest issues families face at Tunnels Beach is finding parking. The road along the north shore is narrow, and dedicated parking is extremely limited.
What families should know:
- The small beach lot at Tunnels fills very early — often by 7:30–8:00 a.m.
- Ha’ena Beach Park, about half a mile away, has more space and is the best backup option.
- From Ha’ena, expect a 10–15 minute walk along the beach to reach Tunnels.
- If you have toddlers or a lot of gear, consider taking the North Shore Shuttle, which stops at Ha’ena Beach Park (check the current shuttle schedule and reservation requirements).
Important: Don’t confuse Ha’ena Beach Park with Ha’ena State Park (near Ke’e Beach), which requires timed entry reservations. Tunnels Beach does not require a permit.
What to Expect When Snorkeling at Tunnels Beach
Once you arrive and walk to the snorkeling area, you’ll see a rocky reef system close to shore. This is the primary area where snorkeling is permitted and safe for families.
In the past, the large inner reef known as Makua Lagoon was a popular snorkeling area, but it is now part of a marine refuge zone within the Hā‘ena Community-Based Subsistence Fishing Area (CBSFA). Snorkeling and swimming in that area are now prohibited to protect coral and fish habitats.
Family-Safe Snorkeling Area:
- The rocky reef near shore has two sections separated by a sandy channel.
- Enter the water to the right of the reef, facing the ocean.
- This zone is protected by the larger outer reef, reducing wave action in summer.
- The depths range from 3 to 25 feet, making it good for families with older kids who are comfortable swimming.
While the visibility can vary (especially after recent wave activity), families can usually see:
- Yellow tangs
- Parrotfish
- Moorish idols
- Occasional green sea turtles
- Small patches of coral and underwater rock formations
Some areas have underwater caves and lava tubes, but these should only be explored by experienced adult snorkelers.
Water Safety Tips for Families
Tunnels is best suited for:
- Older children (10+) who are strong swimmers
- Families with previous snorkeling experience
- Visitors who understand how to check ocean safety conditions
Tunnels is not recommended for toddlers or young children unless an adult remains on shore with them while others snorkel. There are no lifeguards directly at Tunnels Beach, so all snorkeling is at your own risk.
Safety reminders for families:
- Avoid the channel and outer reef — currents can pull snorkelers out to sea.
- Bring reef shoes or enter carefully to avoid cuts from rocks.
- Use flotation belts or snorkel vests for younger or less confident swimmers.
- Never snorkel alone, and always stay within voice range of others in your group.
- If visibility is poor or waves are breaking on the reef, skip snorkeling for the day.
Facilities: Limited at Tunnels, Available at Ha’ena Beach Park
There are no public restrooms, showers, or drinking water at Tunnels Beach. Families should plan to use the amenities at Ha’ena Beach Park, which include:
- Restrooms and outdoor showers
- Covered pavilions and picnic tables
- Drinking water stations
- Shaded areas under trees
Since there are no food vendors, bring your own snacks, lunch, and plenty of water. Consider packing a small cooler and beach umbrella if you plan to stay for a while.
Final Tips for Snorkeling Tunnels Beach with Kids
- Arrive early: It’s the only way to secure parking, avoid crowds, and enjoy calmer water.
- Skip winter visits: Dangerous surf and currents make it unsafe for family snorkeling.
- Respect the reef: Stay out of the restricted Makua Lagoon and avoid stepping on coral.
- Plan ahead: No rentals, restrooms, or shade are available on-site.
Alternative Snorkeling Spots for Families
If Tunnels doesn’t work for your family due to conditions or logistics, consider:
- Poipu Beach Park – Lifeguards, facilities, and safe year-round snorkeling
- Lydgate Beach Park – Enclosed swimming lagoons ideal for toddlers
- Ke’e Beach – More protected in calm summer months (reservation required)
