Niihau Snorkel Tour: The 7-Hour Full-Day Boat Trip from Port Allen

In the $339

The price covers the 7-hour cruise on the Kauai-built catamaran, snorkeling equipment and instruction, ocean-friendly certified sunscreen, a continental breakfast, a deli-style buffet lunch, soft drinks all day and beer and wine after snorkeling. Alcohol is served only after the snorkel stop, and staff check IDs. For a shorter day with the same operator, see the $274 five-hour Holo Holo Sail and Snorkel.

What You Pay on the Day

The listing names no mandatory extras beyond the ticket. Gratuities are explicitly not included. The listing does not mention parking.

Bring a passport or ID card for age verification, swimwear, a towel and a jacket. Pets and smoking are not allowed, and Holo Holo boats run barefoot only.

• Tips for the captain and crew, not included in the price
• Parking near the Waialo Road check-in, which the listing does not mention
• Nothing else is named as a paid extra on this tour

Check-in at Port Allen

You meet at Holo Holo Charters, 4353 Waialo Rd Suite 5A in Eleele, on the south shore of Kauai. The exact starting time appears when you check availability. Holo Holo's own site lists a 6:00 AM check-in for its 7-hour Niihau and Na Pali expedition, so plan for an early start and confirm your time when booking.

Up the Coast, Then Across the Channel

Breakfast is served as the catamaran heads northwest along the Na Pali Coast, a shoreline of about 16 miles. The listing promises waterfalls, lush valleys, hidden beaches and sea caves along the way, with the captain commenting on the history of the region. Sea cave entry depends on the sea, and the captain may wait until check-in to pick the route.

The boat then crosses the Kaulakahi Channel to Niihau, which lies about 17.5 miles southwest of Kauai. Elizabeth Sinclair bought Niihau in 1864 and her Robinson descendants own it. It is off-limits to outsiders, so there is no landing.

You view it from the water.

• Lehua sits 0.7 miles north of Niihau and is a State Seabird Sanctuary
• Lehua snorkel sites hold at least 25 fish species, with monk seal and manta ray visits
• Water temperature runs 74 to 80 F year-round on Holo Holo trips

Snorkel, Lunch, Sail Home

At Lehua Crater the captain chooses the best spot to snorkel and hands out gear with instruction. Routes depend on ocean and weather conditions. Afterwards the deli-style buffet lunch comes out, with fresh bread, meats, cheeses, veggie toppings, crudite and pasta salad, and beer and wine become available.

Crew share stories about Niihau and Kauai culture on the sail back to the Holo Holo marina in Eleele.

• Avoid snorkeling within 24 hours of arriving on a flight over 5 hours
• Routes depend on ocean and weather conditions

Hard Exclusions

Children under 5 are not permitted, and expectant mothers cannot board. People with back problems, recent injuries or surgeries are advised against it, and people prone to seasickness are on the not-suitable list, with no refunds given for seasickness. Wheelchair users are excluded because mobility aids such as canes, walkers, crutches and wheelchairs are not allowed on board.

There is no hotel pickup, so you need your own transport to Eleele. The group size is not stated by the listing.

• Under 5s, pregnant women and wheelchair users: not permitted
• Seasickness: no refund, and 7 hours is a long time to be unwell
• No hotel pickup from anywhere on Kauai

The 7-day Cancellation and the Weather

Free cancellation ends 7 days before departure. Most other trips here give you 24 hours. All routes depend on ocean and weather conditions, and the captain may wait until check-in to decide.

Holo Holo extended cancellations through September 26 after Hurricane Lowell, which closed Kauai state parks from September 8, 2026. If the 7-day window or the full-day length puts you off, the Amelia K Boat Tour runs 5 hours at $227.13 with free cancellation to 24 hours before, and the Lucky Lady Snorkel Cruise gives a 5.5-hour catamaran day from the same harbor for $233.73.

• Full refund only if you cancel 7 days ahead
• Routes and the snorkel stop are never guaranteed
• Likely to sell out, per the listing

Reaching Port Allen

Port Allen Small Boat Harbor sits on the eastern shore of Hanapepe Bay on Kauai's south coast, and it was originally called Eleele Landing. Hanapepe sits about 17 miles west of Lihue by Route 50, so figure roughly 30 to 35 minutes driving from Lihue. The harbor has restrooms, a loading dock and a two-lane launch ramp.

Note that Hurricane Lowell closed all Kauai state parks from September 8, 2026, and while the Port Allen launch ramp reopened on October 2, 2026, slips and moorings stayed closed with extensive damage. Confirm the departure point with the operator close to your travel date, and read the Port Allen Kauai guide for more on the harbor.

• Check-in address: 4353 Waialo Rd Suite 5A, Eleele, HI 96705
• Allow roughly 30 to 35 minutes from Lihue
• Allow for the 6:00 AM check-in Holo Holo lists for its full-day trip

Adding a Day on Land

Waimea Canyon and Polihale State Park, which marks the southwestern end of the Na Pali coast, sit west of Eleele and pair well with an early tour day or the day after. The Kalalau Trail starts at Kee Beach at the end of Highway 560 on the north shore, an 11-mile route through Hanakapiai and into Kalalau Valley. Access runs through Haena State Park, which requires advance day-use reservations, and the park was listed as scheduled to reopen on October 15, 2026 after hurricane-related closures, so check its status before you drive.

In winter, roughly December to April, humpback whales pass Kauai and a dedicated Kauai whale watching trip is worth adding. The Na Pali Coast guide covers the whole shoreline.

• Waimea Canyon drives sit on the same side of the island as Port Allen
• Haena requires advance day-use reservations, so confirm the booking window on the park's site
• Federal rules bar approaching humpback whales within 100 yards
