17) Get A Look At The Queen’s Bath 

One of the best Kauai attractions, the Queen’s Bath, is a favorite summertime activity for locals and tourists on the island. 

The short hike to the Queen’s Bath passes through the rocky landscape of lava rock to natural tide pools. Many walk to the area to dip into the water for a refreshing swim in the rock pools.

It is crucial to proceed with caution, though, as the waves can drag people out into the ocean when the waters are rough. This is most common during the winter when the waters are notoriously more turbulent. 

We do not recommend swimming here. Instead, we recommend enjoying the views at a safe distance to avoid any possible danger. The pools are often closed as well due to rough oceans.

20) Soak In The Views Of The Na Pali Coast

The Na Pali Coast, often spelled Napali Coast, is one of the most incredible natural wonders that you must see when you visit Kauai.

With dramatic sea cliffs covered in rich green jungle, the views here are truly unbelievable.

There are two main ways to see the Napali Coast at its best. Because the landscape is very remote and rugged, hiking is possible, but it’s much easier to fly or sail near the Napali Coast.

So a boat trip across the sea will give you ocean views of the amazing scenery. Book this guided boat cruise and spend a full day sailing over the Pacific and admiring the cliffs from the water.

A helicopter tour is also an epic way to view the cliffs of the Na Pali Coast. It’s a bit more expensive than a boat tour, but a helicopter tour combines all the island’s highlights, including the Waimea Canyon, Wailua River, and Napali Coast!

21) Go Paddle Boarding At Anini Beach

The protected area’s waters are stable, offering prime opportunities for snorkeling and paddleboarding. This spot actually has the longest fringing reef out of all the main Hawaiian Islands!
