The pristine sand beaches, lavish jungle-like rain forests and enormous green cloud-covered mountains with majestic waterfalls cascading down to the beaches below make the island one of the most beautiful places anywhere on Earth. The 22-mile-long (round trip) Kalalau Trail is gorgeous. It provides the only foot access to the spectacular Na Pali Coast and the hidden beaches along the way. Kauai is home to the breathtaking Hali’i Falls where you can actually swim. You can only get to the multifaceted waterfall by hiking through a bamboo forest, which is an adventure in itself.
