This hiking trail can be a bit challenging, but adventurers will be rewarded with a unique experience. A descent through lush rainforest leads to a valley of a solid, yet still steaming lava lake. The scenery of the Kīlauea Iki Crater is barren and desolate, but eerily beautiful.

You have the unique opportunity to watch one of nature's most powerful, beautiful processes as the earth unfurls to release its magma from the volcanoes. As one of the most active volcanoes on the planet, Kīlauea volcano is consistently one of Big Island's biggest attractions. Its reputation precedes it as a sacred place for Native Hawaiians as well. Marvel at the active Mauna Loa, learn about volcanology at the Jaggar Museum, take a selfie at the viewpoint overlooking the Halema'uma'u Crater. The long, underground cave formed by ancient flowing lava called the Thurston Lava Tube (Nāhuku) is another must-see.

The Secret Buddha Garden was built in 1976 by a fruit farmer called Nim Thongsuk and took around fifteen years to finish. This peaceful place can be found in the hills of Samui Island inside the verdant jungle. The garden is decorated with sculptures portraying both humans and deities in various poses. Getting there quite difficult so booking a tour in advance is highly recommended.

Hawaii's black sand beaches are a world-class attraction. Punaluu Black Sand Beach, located on the southeastern Kau coast, draws its striking color from volcanic activity. Hawaiian Green Sea turtles often bask on the shore here — be sure to observe from a distance, as they are an endangered species.
