Blue Pool, Maui, Hawaii. A stop on the Highway to Hana. The Blue Pool, also known by its Hawaiian name Helele'ike'oha, could very well be one of the more scenically located swimming hole waterfalls on Maui. It faces the ocean as it's sheltered from the crashing waves by rocks protecting its picturesque plunge pool.
Big Island, as the name suggests is the largest island in United States and is still growing. Big island is youngest island in the Hawaiian chain and is home of five volcanoes, two out of which are the most active volcanoes in the world.
