What to do in Kauai in October? October in Kauai is kind of the perfect sweet spot. The summer crowds have thinned out, the weather is still warm, and the island is buzzing with green everywhere after the rainy season. There’s a ton to do – from beaches and hikes to waterfalls and local towns. But let’s be honest: nothing, and we mean nothing, shows you Kauai like a helicopter ride. If you do one thing in October, make it that.
Alli Kauai Air Tours and Charters offers aerial tours year-round, so you can see Hawaii like few get to: from a bird’s eye view. Let’s dive into what to do in Kauai in October, and do a deep dive into why a helicopter or air tour is a vacation must-do – regardless of when you’re traveling.

The Na Pali Coast is breathtaking, but getting there on foot or by boat doesn’t compare to seeing it from the sky. Airplane tours on Kauai give you the full picture: cliffs dropping into the ocean, hidden valleys, and waterfalls tucked into spots you can’t reach any other way.
Flying over Kauai feels surreal. You’re looking down at waterfalls pouring into the jungle, streams winding through valleys, and beaches that seem almost private. October is perfect because the skies are usually clear, so the views are amazing.
If you like hiking, Waimea Canyon is a must. Known as the Grand Canyon of the Pacific, it’s huge, colorful, and has a ton of trails for every level. October is one of the nicest months to hike – it’s not too hot, and the island is lush and green from the recent rains.
Even a short trail gives you incredible views of deep valleys, colorful cliffs, and waterfalls hidden in the canyon walls. It’s one of those places that really makes you appreciate how wild Kauai is.
October is quieter than summer, which means more space for yourself on the sand. Hanalei Bay and Poipu Beach are both favorites. You can swim, sunbathe, or just wander along the shore. The water is still warm, and the sunsets? Incredible.
Hawaii is, of course, famous for the Pacific Ocean surrounding it, and you have to get in at least once during your visit. But there are other ways to enjoy the water here too. If you’re looking for adventure, paddleboarding or kayaking on the Wailua River is a great way to get out on the water without the crowds. It’s peaceful, and you can float past waterfalls, lush vegetation, and maybe even spot some wildlife along the way.
Kauai has so many waterfalls that some are impossible to see except from a helicopter. That said, a few are easy to reach. Wailua Falls and Opaeka’a Falls are accessible and absolutely worth visiting. October is great because the recent rains usually mean the falls are flowing strong, but trails aren’t muddy like in the wettest months.
We can’t stress this enough: if you’re visiting Kauai in October, book a helicopter ride. It’s honestly the best way to see the island. You get to see the Na Pali Coast, Waimea Canyon, hidden waterfalls, and lush valleys all in one flight.
No matter how long you’re staying, try to fit this in – it’s the one experience that makes you go, “Wow, Kauai is even more amazing than I imagined".
Don’t spend all your time in nature. Hanalei has cute little shops, galleries, and great food. Kapa’a has a relaxed vibe with local cafes and markets. Poipu is a mix of resorts, beaches, and restaurants. Even wandering around these towns gives you a sense of local life, and the pace is slower in October.
Add in a quick paddle on the Wailua River or a stroll through a local market, and you’ve got a full day that mixes adventure with relaxation.
