The Garden Island offers an endless amount of outdoor activity, whether you're looking to hike, kayak, swim or relax on the beach. By and far the most popular attraction on the island is the one-of-a-kind Napali Coast, which is best seen on foot hiking the infamous Kalalau Trail, trekking the edges of Koke’e State Park or from the air on a helicopter tour. You can also explore the waters surrounding the coast via one of the best Kauai boat tours. If you're looking for a little less adventure, consider visiting the lower-impact Wailua River State Park or taking a dip in the calm waters of Poipu Beach Park or Kalapaki Beach. Those more interested in the underwater scenery will be in awe of the views from Hanalei Bay, Ke'e Beach or Tunnels Beach, the latter of which is considered one of the top spots for snorkeling on the island.
