The Diamond Head Crater Hike is one of the most popular walking trails on the island and although it is paved the whole way it is still a steep challenge and a hike with amazing views of Waikiki and the southern coastline of Oahu, Hawaii. This 3km out-and-back trail is one of the most ‘must-do’ activities for visitors staying in Waikiki!
