Ahihi-Kinau, officially known as ‘Āhihi-Kīna‘u Natural Area Reserve, is one of Maui’s most treasured snorkeling spots. Tucked along the island’s rugged southwestern coast, this protected marine ecosystem invites travelers to experience Hawaii’s underwater wonders in a setting largely untouched by development. If you’re seeking crystalline waters, vibrant coral reefs, and a chance to swim alongside Hawaiian green sea turtles, Ahihi-Kinau is for you.
Why Snorkel at Ahihi Kinau?
Ahihi-Kinau offers a truly unique snorkeling experience thanks to its strict conservation measures and the rich ecosystems they protect. As a designated Natural Area Reserve, Ahihi-Kinau has preserved some of the healthiest coral reefs in all of Maui. In these clear, shallow waters, you can observe vibrant reef formations teeming with tropical fish, from the bright yellow tangs to the unmistakable state fish of Hawaii, the humuhumunukunukuāpuaʻa. Many snorkelers also come here hoping to spot Hawaii’s majestic green sea turtles, which often glide gracefully through the reserve in search of food.
Beyond the abundance of marine life, Ahihi-Kinau stands out for its relatively calm conditions. The rugged lava rock formations along the coast help shield the reserve from rough ocean swells, creating gentler waters ideal for both beginners and experienced snorkelers. This sheltered environment makes it easier to enter and exit the water, so you can spend more time marveling at the underwater world and less time battling currents.
Just as important as the snorkeling itself is the reserve’s commitment to eco-friendly travel. Signs posted throughout Ahihi-Kinau remind visitors to refrain from touching or taking anything—fish, shells, or coral—ensuring the ecosystem remains pristine for future generations. By choosing Ahihi-Kinau for your snorkeling adventure and following “leave no trace” principles, you’ll become part of a growing community dedicated to responsible, sustainable tourism. With its unmatched marine life, calm waters, and spirit of conservation, Ahihi-Kinau remains one of Maui’s most rewarding destinations for nature enthusiasts.
Plan your visit
Arriving early at Ahihi-Kinau helps you secure a parking spot and enjoy calmer waters before the midday crowds appear. As you pack for the day, don’t forget reef-safe sunscreen to protect the corals, along with your own snorkel gear, water, and snacks—the reserve has no restrooms or showers.
Keeping an eye on posted signs is essential, as certain areas may be off-limits to allow coral regeneration or protect fish spawning grounds. By planning ahead, you’ll minimize stress, make the most of the reserve’s pristine conditions, and ensure your visit supports the conservation efforts that keep Ahihi-Kinau so special.
Best time to visit
Although Maui’s weather is generally pleasant throughout the year, the most rewarding time to snorkel at Ahihi-Kinau is often during the early morning hours. At this time, the waters are typically calmer, winds are lighter, and visibility tends to be at its clearest.
Many visitors also favor the summer season, when ocean conditions are frequently gentler, making it easier to explore the vibrant coral reefs. While each season has its appeal, planning your visit around these calmer periods can help maximize your enjoyment—and your chance of spotting marine life at its most active.
Location
Ahihi-Kinau is situated along Maui’s rugged southwest coast, just past Makena and on the way toward La Perouse Bay.
Wailea, HI, United States
Ahihi-Kinau is conveniently situated about five miles south of Kihei and roughly one mile beyond Makena Beach (often called Big Beach) along Makena Alanui Road. This scenic drive showcases Maui’s rugged volcanic landscape, passing by black lava fields, low stone walls, and occasional ocean viewpoints that reveal just how close you are to the water’s edge. Look for the sign that reads “AHIHI-KINA’U NATURAL AREA RESERVE,” just past the last of the residential homes, to confirm you’ve arrived. Once inside, you’ll find a small gravel parking area—spaces are limited, so plan to come early to secure a spot. As of October 2020, non-Hawai‘i residents must pay a $5 parking fee, payable by credit or debit card at one of the onsite machines, which then issues a receipt to be displayed on your dashboard.
Because the reserve is strictly protected, parking rules are enforced to maintain traffic flow and safeguard the environment. Cars that park on the shoulder risk being ticketed or towed, so be sure to use only marked stalls. You’ll also want to avoid leaving valuables behind in your car, as break-ins can occur in remote or less supervised areas. Keep in mind there are no restrooms, showers, or other facilities onsite—a testament to Ahihi-Kinau’s wild beauty and focus on preserving its pristine natural state. If you’re traveling from busy resort hubs like Kihei or Wailea, this journey takes around 30 minutes, but rewards you with a sense of stepping back in time to a coastline shaped by centuries of volcanic activity and protected by modern conservation efforts.
Parking and Fees
Parking at Ahihi-Kinau is limited, so arriving early is essential to secure a spot, especially during peak visitor hours in the morning. The main parking area is a small gravel lot located just past the last of the residential homes along Makena Alanui Road. Due to the reserve’s protected status, parking outside designated areas is strictly prohibited. Any vehicles parked along the roadside shoulder risk being ticketed or towed by local authorities, so it’s important to follow all posted parking regulations.
As of October 1, 2020, a $5 per vehicle fee is required for non-Hawai‘i residents to enter and park at the reserve. Payment can be made using one of two automated machines located within the parking lot, which accept credit and debit cards only—cash is not accepted. Visitors must display their printed receipt on their vehicle dashboard at all times while inside the reserve. Hawai‘i residents are not charged a fee but must still obtain a daily pass from the same machines and display it in their vehicle.
The parking fees contribute directly to the upkeep and conservation efforts of Ahihi-Kinau, helping fund infrastructure maintenance and environmental protection initiatives. Since the area is managed as a Natural Area Reserve rather than a recreational park, these fees play a crucial role in preserving its delicate marine ecosystem and archaeological sites.
Visitors should also note that there are no facilities available at the reserve—no restrooms, no showers, and no drinking water stations. Be sure to come prepared with all essentials, and avoid leaving valuables in your car, as break-ins can sometimes occur in remote parking areas. To ensure a stress-free visit, it’s best to arrive early, park legally, and respect the area’s conservation efforts.
