Fun Things to Do in Kauai on Your Next Hawaii Vacation
Kauai is unlike any other Hawaiian island. About 97 percent of the land is undeveloped, which means the moment you land, you're surrounded by raw jungle, sea cliffs, and open sky. If you're planning a trip and want to know the best fun things to do in Kauai, this guide covers the activities that actually deliver, from the island's most dramatic natural landmarks to a night you won't forget at Poipu Beach.
Our Top Picks for Fun Things To Do in Kauai
Explore the Na Pali Coast and Waimea Canyon
These two landmarks sit at opposite ends of the island, and both are non-negotiable stops on any Kauai itinerary.
Waimea Canyon is 14 miles long and over 3,600 feet deep. Known as the Grand Canyon of the Pacific, it's the kind of place that stops you cold the first time you see it. Drive up to the Waimea Canyon Overlook or the Puu O Kila Lookout for views that stretch across layered red and green ridgelines. Bring layers, because the elevation makes it noticeably cooler up top.
The Na Pali Coast is a 17-mile stretch of sea cliffs that you can only reach by boat, helicopter, or on foot via the Kalalau Trail. Each option gives you a completely different experience of the same coastline.
Choose the Right Na Pali Coast Tour for Your Trip
A boat tour works well if you want to get close to the cliffs and have the option to snorkel. A helicopter is the right call if you want sweeping aerial views and don't mind the price. The Kalalau Trail is for experienced hikers only. It's 11 miles one way, rough in sections, and requires a permit for camping beyond the two-mile mark.
Pick your option based on how much physical effort you want to put in and how much time you have on the island.
Hit the Best Beaches and Snorkel Spots in Kauai
Kauai's beaches are spread across all sides of the island, and they're not all the same. Knowing which one suits your plans saves you a wasted afternoon.
Poipu Beach on the South Shore is one of the most consistent beaches on the island for swimming and snorkeling. The reef is close to shore, the water is typically calm, and it's one of the spots where you're most likely to see a Hawaiian monk seal resting on the sand. Tunnels
Beach on the North Shore has one of the largest fringing reefs in Hawaii and is a top choice for snorkeling when the summer swells settle down. Hanalei Bay is a wide, sweeping beach backed by green mountains, and it's ideal for a relaxed afternoon swim during calmer months.
South Shore Beaches vs. North Shore Beaches
The South Shore gets more sun year-round and tends to have calmer water, which makes it the safer choice if you're visiting between November and April. The North Shore is dramatic and lush, but the winter surf can make some beaches unsafe for swimming. If your trip falls outside of summer, lean toward South Shore beaches like Poipu for water activities and save the North Shore for scenic drives and hikes.
Kayak, Hike, and Zip Through Kauai's Garden Island Terrain
Kauai's outdoor activity list is long, and most of it sits well off the resort strip.
Kayaking the Wailua River to Secret Falls is one of the most popular guided experiences on the island. It's a two-mile paddle upstream followed by a short hike to a waterfall. You can do it self-guided or with a tour operator, but first-timers tend to get more out of it with a guide.
The Sleeping Giant Trail on the East Side is a favorite among locals. It's a relatively short hike to a summit with panoramic views of the island, and you can access it from either the north or south trailhead.
If you want a faster pace, zip-lining through the island's interior gives you a bird's-eye look at terrain that most people never see on foot.
Book a Kauai Luau for an Unforgettable Night on the Island
Of all the fun things to do in Kauai, a traditional Hawaiian luau is the one experience that brings together food, culture, music, and the setting of the island all at once.
We're proud to host Kauai's oceanfront luau at 'Auli'i Lū'au, located at Poipu Beach on the South Shore. As a Native Hawaiian-owned experience, everything we do is rooted in authentic Hawaiian values and storytelling. The evening's entertainment includes hula, traditional Polynesian performance, and the Siva Afi fire show.
We offer two packages. The Ali'i package includes premier seating within the first four rows, VIP check-in, a specialty seasonal lei, tableside appetizers, and priority buffet access. The Aloha package includes standard shared banquet seating, a shell lei greeting, and the full luau experience with open bar and buffet.
If you're looking for the single best evening activity on the island, this is it. You can reserve your seat at auliiluau.com.
Plan Your Kauai Vacation Around the Right Time of Year
Kauai has a wet side and a dry side, and the time of year affects which fun things to do in Kauai are open to you.
The island's wet season runs from November through April, and the North Shore takes the most rain during this stretch. That said, showers are often brief, and you can usually plan around them.
Whale watching season runs from mid-December through mid-April, with peak activity in January and March. If humpback whales are on your list, book a boat tour during this window.
Summer, roughly May through September, brings the calmest water conditions on the North Shore, which is when Tunnels Beach and Ke'e Beach are at their best for snorkeling.
Knowing this before you book lets you line up your Kauai activities around what's actually available during your visit, rather than showing up and finding your first choice closed or out of season.
