Kauai
Adventurous travelers flock here in droves for the many heart-pumping excursions the Hawaiian island has to offer. However, Kauai's beaches should not be overlooked. Take a trip to Polihale State Park to check out secluded shorelines that overlook the island's jaw-dropping Napali Coast cliffs. Or, relax on an easily accessible stretch of sand like Poipu Beach Park. Just keep in mind that swimming here can be challenging because of the rough waters, so pay attention to the lifeguards and posted signs.
