Na Pali Coast State Park Kauai, Hawaii
The trail here is narrow and often so crowded that the hike takes up to two hours one way. Bear in mind also that Hanakapi’ai is not a swimming beach—the undercurrents are fierce, and there are no lifeguards. If you have the energy, you can continue along a two-mile inland trail from the beach to Hanakapi’ai Falls, a 120-foot cascade.
On the other side of the wilderness from Ke’e is Polihale State Park, home to Hawaii’s biggest beach—17 miles long and as wide as three football fields. Located on the remote, extreme western end of Kauai (and lacking any kind of facilities), it’s an exceptionally beautiful spot, positioned at the base of the Na Pali cliffs and offering one of the best places on Kauai for watching the sunset. The park includes ancient Hawaiian heiau (temples) and burial sites, views of the neighbouring islands of Ni’ihau and Lehua Rock, and the famed Barking Sands Beach, where your footsteps make a sound like squeaking snow.
